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 / Disc (diameter): 5.50mm to 600mm
Square bar / Flat bar: 3mm to 800mm
Length: Fixed length or random length or based on the customer's special requirement.
Heavy/middle plate via hot rolled: T6 - 200mm X W1000- 2500mm X L1000-12000mm
Forging piece: stepped shafts, other different shapes based on OEM.
