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.
PRODUCT PROFILE AND DIMENSION
Round bar (diameter): 5.50mm to 650mm
Square bar / Flat bar: T6 to 500mm X W3 ~ 1200mm
