What is heat resisting steel?
Heat resisting steel is a kind of special steel that can maintain good mechanical properties and antioxidant properties under high temperature environment. It has high temperature stability, oxidation resistance and creep resistance, can maintain high strength and hardness at high temperatures, not easy to soften and deformation.
Why choose heat resisting steel?
1. High-temperature stability:
heat resisting steel at high temperatures to maintain high strength and hardness, will not occur obvious softening and deformation.
2. Antioxidant properties:
heat resisting steel surface to form a dense layer of oxide film, can effectively prevent oxidation reaction, slow down the oxidation rate of the material.
3. Creep resistance:
heat resisting steel at high temperatures can resist plastic deformation and creep phenomenon, to maintain good shape stability and dimensional accuracy.
4. Good processing performance:
heat resisting steel has good plasticity and weldability, can be convenient for hot processing and welding.
Application of heat resisting steel
heat resisting steel is widely used in aerospace, energy, chemical industry and other fields, mainly including the following aspects:
1. Aerospace field:
heat resisting steel used in the manufacture of aero-engine turbine blades, turbine discs, combustion chambers and other components, as well as aerospace spacecraft insulation materials.
2. Energy field:
heat resisting steel used in the manufacture of thermal power plant boiler supercritical and ultra-supercritical boiler piping and heating surface, and nuclear power plant nuclear reactor pressure vessel and fuel components.
3. Chemical industry:
heat resisting steel is used in the manufacture of chemical equipment reactor, separator, oil cracker pipeline, etc., which can withstand high temperature, high pressure and corrosive media.
4. Other fields:
heat resisting steel is also widely used in metallurgy, machinery, automobile and other fields, used in the manufacture of a variety of parts and tools under high-temperature working environment.
