MELTING PROCESS & APPLICATION
This alloy is generally smelt in Electric arc furnace (EAF), EAF+LF+VD, 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 / disc (diameter) : 6.0 to 820 mm
Square bar / flat bar: 10 to 600 mm
