310S stainless steel is austenitic chromium-nickel stainless steel, with good oxidation resistance, corrosion resistance, because of a higher percentage of chromium and nickel, so that it has much better creep strength, can continue to work at high temperatures, with good high temperature resistance.

316 stainless steel also contains 2-3% molybdenum, in addition to iron, chromium and nickel. The addition of molybdenum significantly improves the performance of 316 stainless steel in certain corrosive environments, especially those containing chlorides. 316 stainless steel is more commonly used in situations requiring higher corrosion resistance.

202 stainless steel is one of the 200 series of stainless steel, which is a stainless steel with low nickel content and high manganese content, because it is a stainless steel developed to save nickel, so its nickel content is relatively low.
