What is Stainless Steel?(according to EN 10020)
•Stainless steels are “stainless” because their chromium
content gives them exceptional resistance to corrosion.

Corrosion resistance
How stainless steel works
•The passive layer avoids corrosion. Regular maintenance with water
rinsing is sufficient to maintain this corrosion resistance

Why the 4 stainless families do they have
different properties?
•Because they have
different atomic

• Outstanding corrosion resistance
• Substantially higher mechanical strength than
other categories
21
Austenitic standards
304/ 304L/321 and 316L/316Ti, 309S
• Corrosion resistance + mechanical properties
• They will remain indispensable:
– Technical requirements
– Cost of change
– Standard-related issues

ArcelorMittal Stainless Europe Initiative
•Parallel to S400 project launched by ISSF on a worldwide basis
ArcelorMittal launched its own product brand linked to its growth strategy

Our ferritic offer
25
Chromium gives to stainless steel its resistance
to localised corrosion
PREPRE
•Thanks to chromium, stabilised ferritic
can reach 304 corrosion resistance
(nickel does not prevent pitting
corrosion)
304 / 1.4307K41 / 441 / 1.4509
Salt spray test (ASTM B117) >1000h
•Only molybdenum-containing ferritic
have better resistance than 304
80% of the corrosion
resistance required are in
this area

Ferritics are emerging as a useful solution in
many applications
28
A new global
awareness
• Customers highly welcome
comprehensive information
of the "Ferritic Solution“
• They better understand the
advantages that ferritics
can provide.
• They are currently in an
intensive testing phase of
ferritics for their
applications

Customer’s feedback on Ferritic substitution

meeting and conference
Paris May 19th, 2008

Conclusion
• Ferritic grades have been developed to offer our customers an
alternative with similar or identical properties to other stainless steel
grades
• Ferritics development: a long term growth lever for stainless market,
not limited to subtitution to austenitics
• Ferritics grades happened to be a less expensive solution
How to deal with increasingly expensive and volatile raw
materials ?
Ferritic stainless steels are clearly the material of the future.
