PRODUCT DESCRIPTION
The alloy is usually produced by 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 annealed condition.
Final heat treatment - solution treatment.
Heavy/middle plate via hot rolled: T6 - 200mm X W100 ~ 1000mm X L1000 ~ 4000mm
Sheet steel via cold rolled: T0.5 - 6mm X W600- 1000mm X L1000 - 2000mm
Steel strip via cold rolled: T0.3 - 3mm X W5 - 300mm X L (or in coil form)
Forging piece: stepped shafts, other different shapes based on OEM.
Pipes / Tubings: OD 3-219 mm, with wall thickness ranging from 0.50 to 35 mm.
