12 Chemical Compositions
Chromium Nickel Stainless Steel-Austenitic
Type 201 A Cr.·Ni.·Mn. analysis of approximately 17% Cr., 4.5% Ni.,
6% Mn. Has
properties very similar to Type 301. Corrosion resistance is
comparable to Type 301 in most applications.
Type 202 A Cr-Ni-Mn analysis of approximately 18% Cr., 4% Ni., 8%
Mn. Comparable
to Type 302 in mechanical properties and ease of fabrication.
Approaches Type 302 in corrosion resistance.
Type 203 EZ A 17% Cr., 6% Ni., and 6% Mn. grade with best machining
characteristics of
the austenitic stainless steels. Mechanical properties and
corrosion resistance ore similar to Type 303.
Type 301
A 17% Cr., 7% Ni. grade used primarily in structural applications
and where high strength plus high ductility is required. Corrosion
resistance is slightly less than Type 302.
Type 302 The ba.sic 18% Cr. 8% Ni. analysis possessing excellent
corrosion resistance to
many organic and inorganic acids and their salts at ordinary
temperatures. Also has good resistance to oxidation at elevated
temperatures. Can be readily fabricated by all methods usually
employed with carbon steels. Cr-Ni grades are nonmagnetic in the
fully annealed condition and cannot be hardened by conventional
heat treatment.
Type 303 The basic 1 8-8 composition with addition of one or more
other elements, usually
phosphorus, sulphur and selenium to improve machinability. Also
used when minimum galling and seizing is desired. Corrosion
resistance under certain conditions may be somewhat lower than Type
302. Special precautions ore usually necessary in welding this
grade. ~
Type 304 Similar to Type 302 in chemical analysis except Carbon is
.08 Max. The lower
carbon decreases susceptibility to carbide precipitation in the 800
to 1550° F. temperature range, making it useful over a wider range
of corrosive conditions than Type 302.
Type 304L An extra low carbon analysis similar to Type 304 except
carbon is .03 Max.
Possibility of harmful carbide precipitation is greatly reduced.
Thus corrosion resistance is not affected by normal welding and
stress relieving applications.
Type 30S A modified type 304 analysis of lower chromium, higher
nickel content to reduce
tendency to work harden when severely cold worked. Particularly
well suited for difficult spinning, forming, perforating, etc.,
where rapid work hardening makes fabrication difficult.
Type 309 A 24% Cr. 12% Ni. steel combininQ excellent resistance to
oxidation with high
tensile and creep strength at elevated temperatures. It resists
oxidation at tempera tures up to 2000° F. under normal
conditions.
Type 310 A 25% Cr. 20% Ni. analysis having slightly higher
oxidation resistance and creep
values than Type 309. lower Coefficient of Expansion gives less
tendency to warp and throw scale in fluctuating temperatures.
Type 314 Essentially Type 31 0 with the addition of approximately
2.50% silicon to increase
resistance to oxidation and to retard carburization.
Type 316 A modified 18-8 analysis containing approximately 2.50°/0
molybdenum.
More resistant to corrosive action of most chemicals, especially
sulphuric acid and fatty acids; less susceptible to pitting and pin
hole corrosion by acetic acid vapors, chloride solutions, etc.
•
Type 316L Similar to Type 316 in analysis excep.t carbon is .03
Max. Possibility of
harmful carbide precipitation is greatly reduced.
(Continued)
Type 317 A modified 18-8 stainless containing approximately 3.50o/0
molybdenum.
Resistance to corrosion is somewhat better and susceptibility to
carbide precipi tation is slightly less than Type 316.
Type 321 A modified 18-8 analysis with titanium (five times carbon
content minimum)
added to make it immune to harmful carbide precipitation.
Type 347 A modified 18-8 analysis with columbium {ten times carbon
content minimum)
added to make it immune to harmful inter-granular corrosion.
Straight Chromium Stainless Steels-Ferritic Type 405
A low carbon, 12°/0 chromium iron containing approximately 0.2°/0
alumi num. Developed for application requiring a non-hardening
analysis in this grade. It is particularly well suited for welded
construction which cannot con veniently be annealed or stress
relieved after welding.
Type 430 A low carbon 17o/0 chromium iron superior to Type 410 in
oxidation re
sistance because of its higher chromium content. It is affected
very little by heat treatment. It is used primarily for nitric acid
equipment, automotive trim, etc. The free machining grade in this
analysis is designated as Type 430-F.
Type 442 A straight chromium ferritic stainless steel with good
corrosion resistance and
resistance to scaling at high temperatures.
Type 446 A high chromium heat resisting steel recommended for
temperatures up to
2150° F under normal conditions. It is superior to Type 310 in
oxidation re sistance but has lower strength and creep values at
elevated temperatures. It is not generally used for applications
involving difficult fabrication because of its low ductility.
Straight Chromium Stainless Steels-Martensitic Type 410
A basic 12°/0 chromium, corrosion and heat resisting grade, which
can be readily heat treated to provide a wide range Of mechanical
properties. It is fairly resistant to mild forms of corrosion. Its
ability to resist atmospheric cor rosion is due to the formation
of a tightly adherent oxide film which protects the surface.
Type 414 A 12°/0 chromium grade with a small addition of nickel for
higher strength
and toughness. Other properties are similar to Type 410.
Type 416 The 12°/0 chromium grade to which one or more other
elements, usually phos
phorus and sulphur, have been added to improve machinability. It is
similar to Type 410 in mechanical properties, but has slightly
lower corrosion resistance.
Type 420 A 12°/0 chromium grade with approximately .35°/0 carbon to
give it more
responsiveness to heat treatment than Type 410. Widely used in the
mfr .. of stainless cutlery. It must be hardened and ground to
obtain max. corrosion resistance.
Type 440 A hardenable 17°/0 chromium steel offering better
resistance to wear than
Type 420. Grade 440-A contains approximately .65 carbon, 440-8
approxi mately .85 carbon, and 440-C approximately 1.10 carbon.
The lower carbon content provides the best ductility, but maximum
hardness results from the higher carbon content. Type 440-C can be
hardened to approximately 60/62 Rockwell C and is used for ball and
roller bearings, valve parts, etc., requiring high hardness
combined with good corrosion resistance.
Type 17-4 PH This grade, containing 17°/0 chromium and 4°/0 nickel,
is normally superior
in corrosion resistance to the regular martensitic chromium types
of stainless steel shown above. 4°/0 copper is added to promote its
precipitation hardening capacity.
Type 17-7 PH Another precipitation hardening stainless steel
developed primarily for sheet,
plate, strip and wire applications. Contains approximately 17°/0
chromium, 7°/0
nickel and 1°/0 aluminum.
Low Chromium Steels-Type 501-2 A 5°/0 chromium intermediate alloy
steel, related to the stainless family,
possessing corrosion and oxidation resistance decidedly better than
the carbon steels but not comparable to the stainless steels.
Molybdenum is usually added to retard grain growth and improve
creep strength at elevated temperatures.

EFFECT OF ALLOYING ELEMENTS Aluminum
Aluminum is probably the most active deoxidizer in common use in
producing steel. It is used in controlling inherent grain
size.
Boron Boron is odded to steel in amounts of 0.0005 to 0.003% to
improve
hordenobility. In combination with other alloying elements, boron
octs os on "intensifier", increasing the depth of hardening during
quenching.
Carbon When a small amount of carbon is added to iron, the
properties
which give steel its great value begin to appear. As the amount of
carbon increase• up to .80 or .90%, the metal becomes harder, pos
sesses greater tensile strength, and, what is most important,
becomes increa•ingly responsive to heat treatment with
corresponding develop ment of very high strength and
hardness.
If carbon were to be increased beyond certain limits in plain car·
bon •teel, the ability to be worked either hot or cold would
disappear almost entirely, and it would begin to assume the
characteri51ic• of cast iron, which usually ha• 1.7 to 4.5%
carbon.
Chromium Chromium increa•e• respon,e to heat treatment. It also
increases
depth of hardness penetration. Most chromium-bearing allays ·can·
tain .50 to 1.50% chromium. Stainles• steel• contain chromium in
large quantitie• (12 to 25%), frequently in combination with
nickel, and posse55 increased resi•tance to oxidation and
corrosion.
Columbium
Columbium in 18-8 51ainless 5teel ha• a similar effect to titanium
in making the steel immune to harmful carbide precipitation and
resultant inter-granular corrosion. Columbium bearing welding elec·
trades are U5ed in welding both titanium and columbium bearing
51ainle55 steels •ince titanium would be lost in the weld arc
whereas columbium is carried over into the weld deposit.
Copper
Copper is normally added in amounts of .15 to .25% to improve
resistance to atmo•pheric corro•ion and to increa•e ten•ile and
yield 5lrength5 with only a slight lo55 in ductility. Higher
5trength properties can be obtained by precipitation hardening
copper-bearing 51eel.
Iron
Iron i• the chief element of steel. Normally commercial iron con·
tain• other elements pre5ent in varying quantities which produce
the required mechanical propertie•. Iron lack• •trength, i• very
ductile and •oft and doe• not re•pond to heat treatment to any
appreciable degree. It can be hardened •omewhat _by cold working,
but not nearly a• much a• even a plain low carbon steel.
Lead
Lead in •feel greatly improve• its machinability. When the lead is
finely divided and uniformly distributed it ha• no known effect on
the mechanical propertie• of the •feel in the strength level• mo•l
commonly specified. It is usually added in amounts from .1 5% to
.35%.
Manganese
Next in importance to carbon is manganese. It is normally present
in all steel and functions both as a deoxidizer and also to impart
•trength and respon•iveness to heat treatrr.ent. Manganese is
usually present in quantities from V.% to 2%, but certain special
steel• are made in the range of 10% to 15%.
(Continued)
EFFECT OF ALLOYING ELEMENTS, cont'd Molybdenum
Molybdenum adds greatly to the penetration of hardness and
increases toughness. Molybdenum tends to help steel resist
softening at high temperatures and is an important means of
assuring high creep strength. It is generally used in comparatively
small quantities ranging from .1 0 to .40%.
Nickel
Nickel increases strength and toughness but is one of the least
effective elements for increasing hardenability. The most general
quantity addition is from 1 to 4%, although for certain
applications, percentages os high as 36% are used. Steels
containing nickel usu· ally have more impact resistance, especially
at low temperatures. Cer tain stainless steels employ nickel up to
about 20%.
Phosphorus
Some phosphorus is present in all steel. In addition to increasing
yield strength and reducing ductility at low temperatures,
phosphorus is believed to increase resistance to atmospheric
corrosion.
Silicon
Silicon is one of the common deoxidizers used during the process of
manufacture. It also may be present in varying quantities up to 1%
in the flnished steel and has a beneficial effect on certain
proper· ties such as tensile strength. It is also used in special
steels in the range of 1.5% to 2.5% silicon to improve the
hardenability. In higher percentages, silicon is added as an alloy
to produce certain electrical characteristics in the so-called
silicon electrical steels and also flnds certain applications in
some tool steels where it seems to have a hardening and toughening
effect.
Sulphur
Sulphur is an important element in steel because when present in
relatively large quantities, it increases machinability. The amount
generally used for this purpose is from .06 to .30%. Sulphur is
detri mental to the hat forming properties.
Tellurium
The addition of approximately .05% Tellurium to leaded steel
improves machinability over the leaded only steels.
Titanium
Titanium is added to 1 8-8 stainless steels to make them immune to
harmful carbide precipitation. It is sometimes added to low carbon
sheets to make them more suitable for porcelain enameling.
Tungsten
Tungsten is used as an alloying element in tool steel and tends to
produce a flne, dense grain and keen cutting edge when used in
relatively small quantities. When used in larger quantities of 17
to 20% and in combination with other alloys, it produces a high
speed steel which retains its hardness at the high temperatures
developed in high speed cutting. Tungsten is also used in certain
heat resisting steel where the retention of strength at high
temperatures is important. It is usually used in combination with
chrome or other alloying elements.
Vanadium
Vanadium, usually in quantities from .15 to .20%, retards grain
growth, even after hardening from high temperatures or after
periods of extended heating,. Tool steels containing vanadium seem
to resist shock better than those which do not contain this
element.

MECHANICAL PROPERTIES OF STEEL The figures shown below are the
result of many tests and
indicate the probable median mechanical expectancy of the steels
listed, based on a 1" round section. In individual tests these
steels may develop results differing widely from those shown. The
size of the section, rolling temperature, permissi· ble variation
within analysis limits and the atmospheric tern· perature at time
of rolling all influence the final mechanical properties of any
steel.
All hot rolled and cold drawn steels are in the as.rolled condition
except where noted. Yield Point shown for Quenched and Tempered
Condition is determined by the "Dividers Method" of ASTM Spec. E8
(latest).

24 Mechanical Properties
EFFECT OF MASS IN THE HEAT TREATMENT OF STEEL
Effect of heot treatment is governed by the composition of the
steel and by the rate of cooling, It is obvious that a 6" round bar
can not be cooled as rapidly as a 1" round bar and therefore the
difference in tlie rate of cooling will affect not only the
hardness of the steel but alsa the depth of penetration of the heat
treatment.
Therefore, as the size or mass of steel of the same composition
under similar conditions of heat treatment increases, there
develops a proportionate change in the physical• properties
produced by the heat treatment.
The following table indicates the approximate relationship between
the physical properties developed In different diameters of several
alloys treated under similar conditions. This is offered as a guide
to show effect of size on heat treatment properties of alloys 1" to
6" round. All tensile specimens were taken at mid-radius (half way
between center and O.D.).
When specifying heat treatment, be sure to take into consideration
the effect of mass on the physical properties of heat treated steel
in the larger sizes.

ASTM-A255 TEST INTERPRETATION How the Jominy End-Quench
Hardenability Test Can be
Interpreted in Terms af Other Mechanical Properties
Standard ASTM-A255 (Jominy) Test
The Jominy sample is normalized and then finish machined to size:
1" diameter for a length of 3 'l's "; with a '/a" flange, 1 'h" in
diameter. This sample is heated Ia the steel's proper quenching
temperature and immediately inserted in the test fixture (see
sketch below). The water is turned on and allowed to flow for about
ten minutes, coming in contact with the bottom of the specimen
only.
After quenching, a flat surface 0.015"" deep is ground lengthwise
on the sample. Along this surface, Rockwell "C" Hardness read ings
are taken at ){6" intervals for a distance af about 2", starting at
the quenched end. This method of quenching only the end of the
specimen provides a very rapid rate of cooling at the quenched end
with progressively slower cooling all the way up to the other end.
Results in all commercial rates of cooling for both oil and water
quenching are thus shown.
The Standard Jominy Test usually serves as a comparison for
hardenability of steels. The test is somewhat limited, in !hat it
reveals only the harden ability of the steel in its asquenched
state. Since most alloy steels are used in a quenched and drawn
condition, it is highly desirable to know the properties obtainable
after such treatment.
Amplifying tlte ASTM-A255 (Jominy) Test
ASTM Test fixture
By amplifying the Jominy Test, it is possible to determine the
approximate mechanical properties of alloy steels after quenching
and tempering at various temperatures. The method is to first
quench the Jominy sample in the standard way. Next we subject it to
a tempering operation before we grind it and take hardness read
ings. Then by using Tables of mechanical properties, we interpret
the tensile strength, yield point, elongation, reduction of area
and Brinell hardness from the hardness readings which represent the
condition of the steel after having been quenched and
tempered.
Example
For example: Here is the step by step method for determining the
mechanical properties at the center of a 3" round bar, oil quenched
and tempered at 1000 o F.
Prepare the Jominy Sample. Harden it in the Jominy fixture and
temper it at 1000° F. Grind the surface of the sample and take
Rockwell "C" Hardness readings.
In Table A you will find that a 3" round, oil quenched, cools at a
rate of 12.4° F. per second at the half radius.
In Table B you will find that a Jominy sample has a cooling rate of
12.4 ° F. per second at a point 'l's" from the quenched end.
Note the Rockwell reading at the point 'l's" from the quenched end,
because at that point the Jominy sample has the same cool ing rate
as the half radius of a 3" round bar, oil quenched. Let us assume
that the Rockwell reading at this point was 40.
Table C gives the relationship between Rockwell Hardness and the
other mechanical properties. In this case, with Rockwell "C"
reading 40, the other mechanical properties would be: Brinell Hard
ness 379; Tensile Strength P.S.I. 178,000 to 201,000; Yield Point
P.S.I. 163,000 to 179,000; % Elongation in 2 inches 12.5 to 16; and
% Reduction of Area 40 to 49. (Continued on next page)

ASTM-A255 TEST INTERPRETATION-(Cont'd) The cooling rates of various
sized bars, at different locations as
listed in Table A, frequently do not correspond exactly with the
Jominy cooling rates furnished in Table B. Judgment must be used in
these instances in selecting figures in between those listed. This
suggestion also applies to interpretations for intermediate size
bars.

Table C-Approx~mate Mechanical Properties in Relation to
Hardneu
These figures are based entirely on hardness and show only prob
able mechanical properties usually associated with hardness. These
flgures are reasonably accurate for properly quenched steels but
will be misleading if interpreted to apply to steels of lower than
15 or higher than 42 Rockwell C hardness. This table is apt to be
mare accurate for alloy steels of .30 carbon or higher. Low carbon
steels produce yield points less than those indicated.
