MELTING PROCESS
This alloy is generally smelt in Electric Arc Furnace (EAF), EAF+LF+VD, LF + Electroslag remelting (ESR). For a purpose of superior quality, it should be smelt via technology of vacuum refining or by agreement.
PROFILE AND AVAILABLE DIMENSIONS
Round bar / Disc / Rod (diameter): 5.5 ~ 550mm
Square bar / Flat bar: 10mm to 800mm
Length: Fixed length or random length or based on the customer's special requirement.
