MELTING PROCESS
The alloy is usually produced by BEF + AOD / EAF, followed by electroslag refining (ESR or VAR ) if necessary for special purpose.
PROFILE & DIMENSIONS
Round bar / disc (diameter): 6.0 ~ 800mm
Wire rod (diameter): 0.5 ~ 13mm
Flat bar (thickness X width): 10 ~ 400 X 15 ~ 650mm
Length: random length, or based on the customer's special requirement.
Form: wire or straightened bar
