Stainless steel 304 is an austenitic grade of stainless steel that contains high nickel content, typically somewhere between 8 and 10.5 percent by weight and a high amount of chromium that comprises approximately 18 to 20 percent by weight. The lower carbon content of grade 304 stainless steel minimizes chromium carbide precipitation from welding and the alloy’s susceptibility to intergranular corrosion.
304 stainless strip can achieve high hardness and strength through cold working. In the annealed condition, type 304 stainless steel strip is very ductile and can be cold worked easily through operations like roll forming, deep drawing, bending, and other common manufacturing processes. Stainless steel 304 strip is often specified for these characteristics given its high ductility, excellent drawing, forming, and spinning properties. The alloy work hardens rapidly, but in-process annealing is sometimes necessary to restore desirable ductility characteristics and lower hardness.
The 304 grade of stainless steel is known to have better corrosion resistance than Type 302. In regards to magnetic properties, 304 stainless steel is essentially non-magnetic, and only becomes slightly magnetic when cold worked. It has resistance to moderately aggressive organic acids is a result of the 9 to 11% nickel that the 304 alloys contain. Type 304 stainless steel strip also has resistance to corrosion in oxidizing environments is a result of the 18 to 19% chromium that the 304 alloys contain.
The alloy also exhibits excellent toughness, even down to cryogenic temperatures. On the other side of the spectrum, in terms of resistance to oxidation, this stainless steel alloy can be exposed to temperatures of about 1650F continuously appreciable scaling.
Type 304 can be easily welded using common fusion and resistance methods, like most other austenitic grades.
