The molybdenum content of 316L molybdenum-containing stainless steel is generally 3% to 4%, the maximum carbon content is 0.03%, and L represents low carbon. As a low carbon series of 316 stainless steel, it has the same performance as 316 stainless steel, and it has excellent resistance to intergranular corrosion. It is especially suitable for products with special requirements for grain boundary corrosion. It has good properties against chloride stress corrosion cracking and can be used in areas where it cannot be annealed after welding and requires maximum corrosion resistance. For example: used in the marine sector, oil and gas industry, chemical processing industry, petrochemical industry, etc.
