310S Stainless Steel Plate
310S stainless steel is an austenitic chromium-nickel stainless steel with good oxidation resistance, corrosion resistance, and high temperature resistance. Because of the higher percentage of chromium and nickel, it has much better creep strength and can continue to operate at high temperatures. Has 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, 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 with the addition of elements such as molybdenum, tungsten, niobium and titanium. Because of its structure of face-centered cubic structure, Therefore, it has high strength and creep strength at high temperature. The melting point is 1470℃, and it starts to soften at 800℃, and the allowable stress continues to decrease.
310S (old grade 0Cr25Ni20/new grade 06Cr25Ni20) is 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. It can work continuously and has good high temperature resistance.
