technical data (cont’d)typE 304 Vs typE 316 staINlEss stEEltypE 304type 304, with its chromium-nickel content and low carbon, is the most versatile and widely used of the austenitic stainless steels. type 304 alloys are all modifications of the 18 percent chromium, 8 percent nickel austenitic alloy. applications for this group of alloys are varied and all possess somewhat similar characteristics in resistance to oxidation, corrosion, and durability. all provide ease of fabrication and cleaning, prevention of product contamination and offer a variety of finishes and appearances.

gENEral prOpErtIEs typE 304type 304 stainless steels can meet a wide variety of physical requirements, making them excellent materials for applications including auto molding and trim, wheel covers, kitchen equipment, hose clamps, springs, truck bodies, exhaust manifolds, stainless flatware, storage tanks, pressure vessels and piping.

typE 304 rEsIstaNCE tO COrrOsIONthe 18 percent chromium, 8 percent nickel, provides good resistance to moderately acidic or caustic solutions. type 304 may be considered to perform similarly in most non-severe applications. a notable exception is in the case of welding. low carbon (304l) is the recommended alloy and provides increased resistance to intergranular corrosion.

typE 316type 316 is an austenitic chromium-nickel stainless and heat-resisting steel with superior corrosion resistance as compared to other chromium-nickel steels when exposed to many types of chemical corrodents such as sea water, brine solutions, and the like.

gENEral prOpErtIEs typE 316type 316 alloy is a molybdenum bearing stainless steel. it has a greater resistance to chemical attack than the 304 family. similarly, type 316 is durable, easy to fabricate, clean, weld and finish.
