MELTING PROCESS & APPLICATION
This alloy is generally smelt in Basic Electric Furnace (EAF, AOD) or VIM + Electroslag remelting (ESR). For a purpose of superior quality, it should be smelt via technology of vacuum refining or by agreement. It is suitable for applications such as high tensile shafts, bolts and nuts, gears, pinions spindles and so on. These products have been used typically for parts requiring both corrosion and oxidation resistance.
