PRODUCT DESCRIPTION
The alloy is usually produced by VM /CVM followed by electroslag refining (ESR), Vacuum Arc Melting (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) 0.10mm to 300mm
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 W200- 1000mm X L1000-2000mm
Forging piece: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
