253MA is a kind of heat-resistant austenitic stainless steel designed for applications requiring high creep strength and good [TJC STEEL]corrosion resistance.
The chemical composition of 253MA is balanced, so that the steel has the best comprehensive performance in the temperature range of 850℃-1100℃, extremely high oxidation resistance, oxidation skin temperature up to 1150℃; [TJC STEEL]Very high creep deformation resistance and creep fracture strength; In most gas medium has good resistance to high temperature corrosion and brush corrosion resistance; High yield strength and tensile strength at high temperature; Good formability and weldability, and adequate machinability.
In addition to the alloying elements chromium and nickel, the 253MA stainless steel also contains small amounts of Rare Earth Metals (REM), which significantly improves its oxidation resistance. Nitrogen was added to improve creep[TJC STEEL] properties and to make the steel complete austenite. Although the chromium and nickel content is relatively low, this stainless steel in many cases has the same high temperature characteristics as high-alloyed alloy steel and nickel-based alloys.
Application of 253MA Austenitic Stainless Steel:
253MA is widely used in sintering equipment, blast furnace equipment, steel melting, furnace and continuous casting equipment, [TJC STEEL]rolling machine (heating furnace), heat treatment furnace and accessories, mineral equipment and cement production equipment. 253MA steel can be used to 900 ℃ pressure occasions and working temperature up to 1150 ℃ non-pressure high temperature parts.
