The alloy is usually produced by BEF + AOD / BEF / EAF + VD + LF 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 and tempered + Stress relief annealing.
Chemical equipments and parts.
Mechanical parts used in the condition of corrosion resistance.
Bolt and nut, Valve and pipings, Pressure vessel.
Round bar / Wire rod (Diameter): 5.5mm to 500mm
Square bar / Flat bar: 10mm to 800mm
Length: Fixed length or random length or based on the customer's special requirements.
Forging piece: stepped shafts / other different shapes based on OEM.
