310S stainless steel has good high temperature resistance. When the temperature exceeds 800, it begins to soften and the allowable stress begins to decrease continuously. The maximum service temperature is 1200 ¡æ. 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. High temperature resistant steel pipes are specially used for manufacturing electric furnace tubes. After increasing the carbon content in austenitic stainless steel, 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, adding molybdenum, tungsten, niobium and titanium Because of its face centered cubic structure, it has high strength and creep strength at high temperature.
