304 stainless steel (AMS 5513), often referred to as 302, is the most common austenitic stainless steel grade. 304 SS contains a higher chromium and lower carbon content than other variations of type 302. It can be used in an "as welded" condition, while 302 must be annealed. AISI 304 is used in a variety of household and industrial applications, especially fasteners and food processing equipment. Type 304 materials can be used in the welded condition as opposed to the annealed condition and still maintain resistance to corrosion and lend themselves to many types of fabrication. These grades resist corrosion and are often used in the food industry.
