S30815/ 253Ma alloy has the following features:
        253MA is a heat-resistant austenitic stainless steel (Austeniticstainlesssteel), require high creep strength (creepstrength), and good corrosion resistance force applications. Its operating temperature range of 850 ~ 1100 ℃. 253MA chemical composition is balanced so that the steel has the most suitable combination of properties within a temperature range of 850 ℃ -1100 ℃, high resistance to oxidation, since oxidation of the skin temperature up to 1150 ℃; high resistance to creep type variable ability and creep rupture strength; has good resistance to high temperature corrosion resistance and resistance to corrosion in the most balanced brush gaseous medium; a higher yield and tensile strength at high temperature; good formability and weldability as well as adequate machinability. In addition to the alloying elements chromium and nickel, 253MA stainless steel also contains small amounts of rare earth metals (RareEarthMetals, REM), which significantly improved its antioxidant capacity. Adding nitrogen to improve the creep properties of the steel and to become a fully austenitic. Although chromium and nickel content is relatively low, but the high temperature properties of stainless steel with a high alloyed steel and nickel-based alloys in many cases the same. 253Ma Application field: 253MA widely used in sintering equipment, blast furnace equipment, steel melting furnace and continuous casting equipment, rolling mill (oven), heat treatment furnace and accessories, mineral equipment and cement production equipment.
