PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VIM / VOD 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 - QT + SRA.
AVAILABLE SHAPES
Round bar / flat bar / square bar / ring / valve body / plate
Bright - peeled + polishing /centerless grinding /peeled + slidabrading
Forged - ring /pipe casing /discs /shaft
INVENTORY - Forged bar diameter 50 ~ 210mm, ESR ingot.
PROFILE & DIMENSIONS
Round bar / rod / disc (diameter): 6.0mm to 800mm
Square bar / Flat bar: 10mm to 600mm
Plate / Sheet steel / Steel strip: 0.5mm to 300mm
Width: 8mm to 1000mm
Length: random length or based on the customer's special requirement.
Forged steel shape: stepped shafts, and other different shapes based on OEM.
