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