PRODUCT DESCRIPTION
The alloy is usually produced by BEF & AOD & VIM followed by electroslag remelting (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 or Q+T condition.
