Description
18/8 stainless steel is also konwn as 304 stainless steel, it refers to the chemical composition of steel containing 18% chromium (Cr) and 8% nickel (Ni). The steel containing 18% chromium and 8% nickel includes 304 and its variants 304L, 304N and 304LN. 18/8 steel is the most widely used material, has excellent corrosion resistance in mild environments, and has good weldability and mechanical properties. The tables below list the 18/8 stainless steel properties including chemical composition, physical and mechanical properties. For full datasheet and specification, please view AISI 304, 304L. 18-8 stainless steel composition is given in table below.
