The introduction of molybdenum in the alloying process improves the corrosion resistance of China Stainless steel-316. It is very similar to Type 304 and is almost as commercially popular – the main differences are that the alloy is stronger at elevated temperatures and corrosion resistance is better, especially in chloride environments. With excellent weldability, good machinability and excellent pitting resistance, China Stainless steel-316 is used in the fabrication of pressure vessels and heat exchangers.Type 316L is a low carbon version of Type 316 which minimizes carbide precipitation due to welding.
