PRODUCT DESCRIPTION
The alloy is usually produced by BEF / BEF + AOD / EAF, followed by electroslag refining (ESR or VAR ) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' specific requirements.
Round bar / rod (diameter): 5.5 to 450mm
Square bar / flat bar: 8 to 600mm
Length: random length or based on the customer's special requirement.
Heavy/middle plate via hot rolled: T6 ~ 400 X W200 ~ 1000 X L1000 ~ 2000mm
Forging piece: stepped shafts, other different shapes based on OEM.
