MELTING PROCESS
This alloy is generally air melted of Non-VIM + ESR, Electric Arc Furnace (EAF), EAF+LF+VD, EF + Electroslag remelting (ESR). For a purpose of superior quality, it should be smelt via technology of vacuum refining or by agreement.
PROFILE AND AVAILABLE SIZE
Round bar (Diameter): 5.5mm to 450mm
Square bar / Flat bar: THK1.0 to 200mm X Width 3 ~ 450mm
