PRODUCT DESCRIPTION
The alloy is usually produced by EAF / AOD / BEF 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.
PROFILE & DIMENSIONS & PROCESSING SERVICE
Round bar & Disc (diameter): 5.5 ~ 600mm
Square bar / Flat bar: 6 ~ 650mm
Length: Fixed length or random length or based on the customer's special requirement.
Heavy / middle plate via hot rolled: T10 ~ 410 X W20 ~ 1000 X Lmm
Sheet steel via cold rolled: T0.5 - 6 X W60 ~ 1000 X Lmm
Steel strip via cold rolled: T0.1 - 3 X W5 - 1000 X L (or in coil form)
