310S(SUS310S,0Cr25Ni20,S31008,1.4845)

Product introduction
310S stainless steel is austenitic chrome-nickel stainless steel, with good oxidation resistance, corrosion resistance, high temperature resistance, because of a higher percentage of chromium and nickel, it has much better creep strength, continuous operation at high temperatures, with 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. The high temperature resistant steel pipe is specially used in the manufacture of electric heating furnace pipe and other occasions. After increasing the content of carbon in Austenitic stainless steel, the strength is improved due to its solid solution strengthening effect. The chemical composition of Austenitic stainless steel is based on chromium and nickel with molybdenum, tungsten, niobium, titanium and other elements. Because of its face-centered cubic structure, it has high strength and creep strength at high temperature. Melting point 1470℃, 800℃ began to soften, the allowable stress continued to decrease.
