MELTING PROCESS
This alloy is generally smelt in Electric Arc Furnace (EAF), EAF+LF+VD, LF + Electroslag remelting (ESR).
For a purpose of superior quality, it should be smelt via technology of vacuum refining or by agreement.
PROFILE AND DIMENSIONS
Round bar (Diameter): 5.50 to 550mm
Square bar / Flat bar: T3 to 500mm X W3 ~ 1200mm
