SUH616 Alloy steels with high strength and good chemical stability at high temperature. It includes two categories: antioxidant steel and heat-strong steel. Antioxidant steel generally requires good chemical stability, but the load is low. Thermal steel requires higher high temperature intensity and corresponding antioxidants. Thermal steel is commonly used to make parts that work at high temperatures at high temperatures in industrial departments such as boilers, turbines, power machinery, industrial furnaces and aviation, petrochemical industry. In addition to the high temperature intensity and anti-high temperature oxidation and corrosion, these components also require sufficient toughness, good processed and weldability, and certain tissue stability according to different uses. In addition, some new low-chromium nickel antioxidant steel types have been developed.
