Stainless steel has good high temperature resistance. When the temperature exceeds 800[1], it begins to soften, and the allowable stress begins to decrease continuously. The maximum service temperature is 1200℃. Due to the high content of nickel (Ni) and chromium (Cr), 316 stainless steel bars have good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. After the content of carbon, 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, and elements such as molybdenum, tungsten, niobium and titanium are added. structure, thus high strength and creep strength at high temperature.
