MELTING PROCESS
This alloy is generally smelt in BEF + ESR, 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.
FROMS & DIMENSIONS
Round bar (Diameter): 5.5mm to 750mm
Square bar / Flat bar: T3 to 500mm X W3 ~ 1000mm
