MELTING PROCESS
This alloy is generally smelt in Non-vacuum furnace + ESR, Electric Arc Furnace (EAF), EAF+LF+VD, LF + ESR.
For a purpose of superior quality, it should be smelt via technology of vacuum refining or by agreement.
PRODUCT PROFILE AND AVAILABLE FORMS
Round bar (Diameter): 0.50 to 450mm
Square bar / Flat bar: T3 to 500mm X W3 ~ 1200mm
