MELTING PROCESS
Heat resistant steel is generally smelt in electric arc furnace (EAF ) or induction furnace + Electroslag remelting (ESR). For a purpose of higher quality, it should be smelt via technology of vacuum refining and external refining.

PRODUCT APPLICATION
Heat resisting steel is widely used in the field of manufacturing the boiler, steam turbine, motive power machine, 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.
