304 / 304L stainless steel
304 / 304L stainless steel, also known as 18/8 stainless and often referred to as 302, is the most common stainless steel. 304 stainless steel 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. 304L is an even lower carbon version of 304 stainless steel and can be used in more corrosive environments such as salt water and chemical containers.
Both 304 and 304L 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.
