316 stainless steel and 316L steel difference. 317 stainless steel and 316 stainless steel (317 stainless steel see below) is a molybdenum stainless steel types. 317 stainless steel molybdenum contents in gaoming in 316 stainless steel. molybdenum in steel, overall performance than the 310 in the steel and 304 stainless steel under high temperature conditions, when sulfuric acid concentration is less than 15% and is higher than 85%, 316 stainless steel with a wide range of uses. Chloride erosion of 316 stainless steel has good performance, so it is usually used in the marine environment. The maximum carbon content of 0.03 316L stainless steel, can be used to weld cannot be annealed and maximum corrosion resistance purposes.
