304 stainless steel and 316 stainless steel difference

1.the main composition of the metal is different The chromium content of 304 stainless steel and 316 stainless steel is about 16 to 18%, but the average nickel content of 304 stainless steel is 9%, and the average nickel content of 316 stainless steel is 12%. Nickel in metal materials can improve high temperature durability, improve mechanical properties, improve oxidation resistance. 2.corrosion resistance is different 304 stainless steel density of 7.93 g/cm3, high temperature resistance 800℃. 316 stainless steel contains Mo element, so that its corrosion resistance, and high temperature strength has been greatly improved, high temperature resistance can reach 1200-1300 degrees, can be used under harsh conditions. 3.Different costs 316 is mainly to reduce the Cr content and increase the Ni content and increase the Mo2%~3%, so its corrosion resistance is stronger than 304, suitable for use in chemical industry, seawater and other environments, similarly, 316 cost is higher than 304, generally 316 used in high requirements, to replace 304. 4.the corresponding brand is different 304 stainless steel corresponding to the Chinese grade 0Cr18Ni9. 316 stainless steel corresponding to the Chinese grade 0Cr17Ni12Mo2.
