316 and 316L stainless steels are molybdenum-containing stainless steels. The molybdenum content of 316L stainless steel is slightly higher than that of 316 stainless steel. Because of molybdenum in steel, the overall performance of 316L stainless steel is better than that of 310 and 304 stainless steel. At high temperature, 316 stainless steel has a wide range of uses when the concentration of sulphuric acid is lower than 15% and higher than 85%. 316 stainless steel also has good chloride corrosion performance, so it is usually used in marine environment. The maximum carbon content of 316L stainless steel is 0.03, which can be used in applications where annealing cannot be carried out after welding and maximum corrosion resistance is required.
