4Cr9Si2
4Cr9Si2 is mainly used for manufacturing parts and components working at high temperature in boiler, steam turbine, power machinery, industrial furnace, aviation, petrochemical and other industrial sectors. In addition to high temperature strength and high temperature oxidation corrosion resistance, these parts also require sufficient toughness, good machinability, weldability and certain organizational stability according to different purposes. China has been producing heat-resistant steel since 1952. Later, some new low alloy heat strength steels have been developed, thus raising the working temperature of pearlitic heat strength steels to 600~620 ℃; In addition, some new low chromium nickel oxidation resistant steel grades have been developed.
