The 253Ma alloy has the following characteristics:
253MA is a heat-resistant austenitic stainless steel designed for applications requiring high creep strength and good corrosion resistance. Its operating temperature range is 850~1100 °C.
The chemical composition of 253MA is balanced, which makes the steel have the most suitable comprehensive properties in the temperature range of 850 °C-1100 °C, extremely high oxidation resistance, and the scale temperature is up to 1150 °C; extremely high creep resistance Capacity and creep rupture strength; good resistance to high temperature corrosion and resistance to brush corrosion in most gaseous media; high yield strength and tensile strength at high temperatures; good formability and weldability And enough machinability.
In addition to the alloying elements chromium and nickel, 253MA stainless steel also contains a small amount of rare earth metal (Rare Earth Metals, REM), which significantly improves its antioxidant capacity. Nitrogen is added to improve creep properties and make this steel a complete austenite. Although the chromium and nickel contents are relatively low, this stainless steel has many of the same high temperature characteristics as the high alloyed alloy steel and nickel-based alloy.
253Ma applications:
253MA is widely used in sintering equipment, blast furnace equipment, steel melting, furnace and continuous casting equipment, rolling mills (heating furnaces), heat treatment furnaces and accessories, mineral equipment and cement production equipment.
