What is the chemical composition of S31603 stainless steel?

S31603 stainless steel is an ultra-low carbon austenitic stainless steel, which is the digital code of American standard 316L stainless steel. It has a lower carbon content based on 316 stainless steel and has excellent corrosion resistance, especially to various organic acids, inorganic acids, alkalis, salts, etc.
S31603 stainless steel has good welding performance, is suitable for multi-layer welding, does not require heat treatment after welding, and has no tendency to knife edge corrosion.
