MELTING PROCESS
The alloy is usually produced by BEF + AOD / EAF, followed by electroslag refining (ESR or VAR ) if necessary for special purpose.
PROFILES & DIMENSIONS
Round bar / disc (diameter): 6.0 ~ 900 mm
Flat bar (Thickness X Width): 10 ~ 400 X 15 ~ 1000mm
Length: random length, or based on the customer's special requirement.
Form: wire or straightened bar
