Heat-resistant steel castings classification
author:adminread:1007

heat-resistant steel castings means of steel at high temperatures. Closely related to the development of heat-resistant steel castings and technological progress power plants, boilers, gas turbines, internal combustion engines, aircraft engines and other industrial sectors.

Antioxidant steel: at high temperature (at 550 ~ 1200 ℃) has good oxidation resistance and high-temperature corrosion resistance, high temperature strength and a certain degree. Components used in the manufacture of various types of furnaces and heat exchangers, manufacturing combustion turbine hot city, Diaogua boiler, heating furnace floor and furnace tubes and roller. Oxidation resistance is the main indicator, the components themselves are not under great pressure. & Nbsp;

heat resistant steel: high temperature (at 450 ~ 900 ℃) can not only withstand considerable additional stress but also has excellent resistance to oxidation and high-temperature gas corrosion, usually required to withstand cyclical variable stress. Typically used as a steam turbine, gas turbine and rotor blades, boiler superheater, bolts and springs working under high temperature, intake and exhaust valves of an internal combustion engine, petroleum and other hydrogenation reactor.
