310S stainless steel is austenitic chromium-nickel stainless steel with good oxidation resistance, corrosion resistance and high temperature resistance. Because of the higher percentage of chromium and nickel, it has much better creep strength and can continue to work at high temperatures. Has good high temperature resistance. Due to the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. After the content, the strength is improved due to its solid solution strengthening effect. The chemical composition characteristics of austenitic stainless steel are based on chromium and nickel with elements such as molybdenum, tungsten, niobium and titanium added. Therefore, it has high strength and creep strength at high temperature. The melting point is 1470 ℃, and it begins to soften at 800 ℃, and the allowable stress continues to decrease.
