Heat resistant steels hold main features, such as oxidative stability, enough high temperature strength, excellent heat resistant quality under hight temperature. Heat resistant steel divides into oxidation resistant  steel (or called non-scaling steel) and refractory steel according to its performance. Heat resistant steel also divides into austenitic heat resistance steel, martensitic heat resistant steel, ferritic heat resistant steel and pearlite heat resistant steel according to normalizing structure.
 

Application field:

Heat resistant steels are widely used in the field of processing boiler, steam turbine, industrial furnace, and other mechanical parts of aviation, petrochemical engineering operating at high temperature. Those parts must hold the features: high temperature strength,resistance to high temperature oxide etch,enough toughness,excellent machinability, weldability, structure stability based on different usages.

 
Manufacturing technology - Smelting
 
Heat resistant steel is generally smelt in electric arc furnace or induction furnace.
For higher quality,it should be smelt via technology of vacuum refining and external refining.
 
 
These materials must stand up to high heat, extreme oxidation potential and cycling
