MELTING PROCESS
Grade X12CNDV12 alloy is usually produced by BEF + VD, followed by electroslag refining (ESR or VAR ) if necessary for special purpose.
PROFILE & DIMENSIONS
Round bar (diameter): 5.5 ~ 550mm
Flat bar (width X thickness): 1 ~ 400 X 4 ~ 800mm
Length: random length or based on the customer's special requirement.
Forgings: per buyer's requirement.
