MANUFACTURING TECHNOLOGY - SMELTING
Heat resistant steel is generally smelt in electric arc furnace (EAF) or induction furnace (BEF). For higher quality, it should be smelt via technology of vacuum refining and external refining.
Heat resistant steel is generally smelt in electric arc furnace (EAF) or induction furnace (BEF). For higher quality, it should be smelt via technology of vacuum refining and external refining.
Martensitic heat resistant steels adopt hardening and tempering to stabilize the structure for excellent composite mechanical properties and high temperature strength.
