The alloy is usually produced by AOD / EAF VD / VIM 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 softened condition.
Final heat treatment - solution treatment / QT
Round bar / flat bar / strip / forgings / plate
Bright - peeled + polishing, centerless grinding
Forged - ring, tube, pipe casing, discs, shaft
Round bar / Wire rod (Diameter): 5.5mm to 500mm
Square bar / Flat bar: 3mm to 1000mm
Plate / Sheet steel / Steel strip: 0.1mm to 1000mm
Width: 8mm to 1200mm
Length: random length or based on the customer's special requirement.
Forged steel shape: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
Mechanical parts used in the condition of corrosion resistance
