253MA is a heat resistant austenitic stainless steel designed for applications requiring high creep strength and good corrosion resistance. The chemical composition of 253MA is balanced, which makes the steel have the most suitable comprehensive performance 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.
If our 253ma bolts caters to your requirement, welcome to contact our professional manufacturers and suppliers. Highly qualified products, competitive price and good after-sale service can be assured.
