The following tables give SS 304 stainless steel properties and specifications (datasheet) including chemical composition, physical and mechanical properties, heat treatment, corrosion resistance, machinability and machining, welding, etc. Therefore, 316 SS is widely used in marine applications. The addition of molybdenum can enhance the resistance to pitting and crevice corrosion caused by chloride. The second most widely used 316 grade stainless steel, compared with AISI 304, reduced chromium content, increased nickel content, and added 2-3% molybdenum. There are several variants of 304 grade stainless steel, such as ultra-low-carbon version type 304L, nitrogen-containing version 304N, 304H with improved creep performance, and type 302 with higher carbon content. The high nickel-chromium alloy content gives it excellent corrosion resistance and is widely used in the food industry as a standard food grade stainless steel. Type 304 has good resistance to atmospheric corrosion and oxidation. SS 304 is non-magnetic under annealing conditions, but after cold working (such as stamping, stretching, bending, rolling), part of the austenite structure may be converted into martensite and therefore weakly magnetic. AISI 304 Stainless Steel (UNS S30400, SS 304)ĪISI 304 stainless steel (UNS S30400) is the most widely used stainless steel, containing 18-20% Cr and 8-10.5% Ni, and also known as 18-8 stainless steel.
