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 black/bright in the annealed condition.
Final heat treatment - solution treatment / QT
Round bar / rod (diameter): 5.5mm to 600mm
Square bar / Flat bar: 10mm to 800mm
Length: Fixed length or random length or based on the customer's special requirement.
Heavy/middle plate via hot rolled: T10 - 400mm X W15 - 1000mm X L1000 - 5000mm
