PRODUCT DESCRIPTION
The alloy is usually produced by BEF /EAF + VD followed by electroslag refining (ESR) 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 / disc (diameter): 6.0 to 600 mm
Square bar / flat bar: 8 to 600 mm
Length: random length or based on the customer's special requirement.
Heavy/middle plate via hot rolled: T6 ~ 200 X W20 ~ 1500 X L1000 ~ 12000 mm
Forging piece: stepped shafts, and other different shapes based on OEM.
