MELTING PROCESS & APPLICATION
This alloy is generally smelt in Electric Arc Furnace EAF, BEF + 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.
AVAILABLE FORMS & DIMENSIONS
Round bar: 5.5mm to 420mm
Square bar / Flat bar: 10mm to 550mm
