FEATURES AND CLASSIFICATIONS
Heat-resistant steel means one type of steel possesses inoxidizability, enough high-temperature strength and excellent heat-resistant quality under high temperature. Heat resistant steel is divided into oxidation resistant steel and refractory steel according to its performance. Further into Austenitic heat-resistant steel, Martensitic heat-resistant steel, Ferritic heat-resistant steel and Pearlitic heat-resistant steel according to its normalizing.

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.
