310S (old grade 0Cr25Ni20 / new grade 06Cr25Ni20) is austenitic chrome-nickel stainless steel with good resistance to oxidation and corrosion. Due to the higher percentage of chromium and nickel, the 310S has much better creep resistance. It can work continuously and 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. High temperature resistant steel pipes are especially used to manufacture electric furnace tubes. Austenitic stainless steel adds carbon After content, resistance is improved due to its reinforcing effect of solid solution. 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. Due to its cubic structure centered on the face, therefore, it has high resistance and resistance to creep at high temperature. The melting point is 1470, and begins to soften to 800, and the permissible tension continues to decrease.
