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 on which the amount of machining warrants use of a free-machining grade of steel requiring corrosion resistance similar to the 18-8 type stainless steel, bolts, screws, and clevis pins, requiring corrosion resistance up to 371℃ and which may be fabricated by heading or by machining.
