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.
SHAPE & DIMENSIONS
Round bar / rod / disc (diameter): 5.5mm to 850mm
Square bar / flat bar: 10mm to 600mm
Length: Fixed length or random length or based on the customer's special requirement.
Other different shapes based on OEM.
