PRODUCT DESCRIPTION
The alloy is usually produced by BEF + AOD / EAF 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 - quenched or solution.
TYPICAL APPLICATIONS
Chemical equipments.
Mechanical parts used in the condition of corrosion resistance.
Chemical equipments.
Mechanical parts used in the condition of corrosion resistance.
Automobile parts, exhaust pipe, Electronics, Turbine motor blade.
Bolts and nuts, Valve, Pressure vessel.
Round bar / disc (diameter): 6.0 to 800 mm
Square bar / flat bar: 10 to 600 mm
Length: random length or based on the customer's special requirement.
Steel strip via cold rolled: T0.5 ~ 3 X W10 ~ 200 X L mm (or in coil form)
Forged piece: stepped shafts, other different shapes based on OEM.
