PRODUCT DESCRIPTION
The alloy is usually produced by AOD 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' requirements.
Bars are usually supplied black/bright in the softened condition.
Final heat treatment - solution treatment.
PRODUCT FORMS AND DIMENSIONS
Round bar (diameter): 5.5mm to 400mm
Square bar / Flat bar: 10mm to 600mm
Plate / Sheet steel / Steel strip: 0.1mm to 300mm
Width: 8mm to 1000mm
Length: random length or based on the customer's special requirement.
Forged steel shape: stepped shafts, other different shapes based on OEM.
