PRODUCT MELTING PROCESS
The alloy is usually produced by BEF / EAF VD followed by electroslag refining (ESR) / 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' requirements.
Bars are usually supplied bright in the peeled condition.
Final heat treatment - solution treatment.
Round bar / rod (diameter): 6.0 to 800 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 W15 ~ 1000 X L1000 ~ 6000 mm
