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 : 6.0 to 850 mm
Square bar / flat bar: 10 to 600 mm
Length: random length or based on the customer's special requirement.
Other different shapes based on OEM.
