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.
Rod / round bar / disc (diameter): 6.0 to 950 mm
Square bar / flat bar: 10 to 600 mm
Length: random length or based on the customer's special requirement.
Heavy/middle plate via hot rolled: T6 ~ 400 X W20 ~ 1000 X L1000 ~ 3500 mm
Forging piece: stepped shafts, other different shapes based on OEM.
