Due to the high content of nickel (Ni) and chromium (Cr), 310S stainless steel has good oxidation resistance, corrosion resistance, acid and alkali resistance. After increasing the content of carbon 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 to add molybdenum, tungsten, niobium and titanium, and because of its face-centered cubic structure, it has high strength and creep strength at high temperatures. 310S stainless steel is often used in the manufacture of boiler, steam turbine, industrial furnace and aviation, petrochemical and other parts of the industry.
