PRODUCT DESCRIPTION
The alloy is usually produced by AOD / EAF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the solution annealing condition.
Final heat treatment - heat treatment / QT / solution treatment
PRODUCT PROFILE & DIMENSIONS
Round bar / Disc (diameter): 5.5mm to 600mm
Square bar / Flat bar: 10mm to 600mm
Plate / Sheet steel / Steel strip: 0.5mm to 1000mm
Forged steel shape: stepped shafts, and other different shapes based on OEM.
