310s stainless steel pipe is a high-alloy stainless steel belonging to the 25Cr-20Ni series. It has excellent high-temperature oxidation resistance. It is suitable for making various furnace components with a maximum temperature of 1200°C and a continuous use temperature of 1150°C. 310s stainless steel pipe has good high temperature resistance. When the temperature exceeds 800, it begins to soften, the allowable stress begins to continue to decrease, and the maximum use temperature is 1200°C. 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 specially used for manufacturing electric furnace tubes. The austenitic stainless steel adds carbon After the content, 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 the addition of elements such as molybdenum, tungsten, niobium, and titanium. Because of its face-centered cubic structure, Therefore, it has high strength and creep strength at high temperature.
