MELTING PROCESS
This alloy is generally smelt in 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.
AVAILABLE FORMS AND DIMENSIONS
Round bar (Diameter): 5.5mm to 450mm
Square bar / Flat bar: THK3 to 200mm X Width 3 ~ 450mm
