310S (0Cr25Ni20) is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance. Because of the higher percentage of chromium and nickel, 310S has much better creep strength, can work continuously at high temperature, and has good high temperature resistance.

 

310S stainless steel is Austenitic Chromium-Nickel Stainless steel, with good oxidation resistance, corrosion resistance, high temperature resistance, because a higher percentage of chromium and nickel, make it have much better creep strength, can continue to work at high temperature, has good high temperature resistance. Because of the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance and high temperature resistance. High temperature resistant steel pipes are specially used to manufacture electric heating furnace pipes. After adding carbon content in austenitic stainless steel, the strength of austenitic stainless steel is improved due to its solid solution strengthening effect. The chemical composition characteristics of austenitic stainless steel are based on chromium and nickel, adding molybdenum, tungsten, niobium and titanium, etc. Elements have high strength and creep strength at high temperature because of their face-centered cubic structure. The melting point is 1470 ~800 ~C, and the allowable stress decreases continuously.
