310S (0Cr25Ni20)/s31008/SUS310S/06Cr25Ni20 austenitic chromium-nickel stainless steel

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 and can continue to work at high temperatures. high temperature resistance.

characteristics:

310S stainless steel is austenitic chromium-nickel stainless steel, which has good oxidation resistance and corrosion resistance of 310S stainless steel. Because of the higher percentage of chromium and nickel, it has much better creep strength and can continue to work at high temperatures. 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. After the content is high, 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 elements such as molybdenum, tungsten, niobium and titanium. Since its organization is a face-centered cubic structure, Therefore, it has high strength and creep strength at high temperature. The melting point is 1470°C, and it begins to soften at 800°C, and the allowable stress continues to decrease.
