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 / Wire rod (Diameter): 0.50mm to 650mm
Square bar / Flat bar: 3mm to 600mm
Length: Fixed length or random length or based on the customer's special requirement.
Heavy/middle plate via hot rolled: T6 ~ 400mm X W200 ~ 1000mm X L1000 ~ 3500mm
Forging piece: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
