PRODUCT DESCRIPTION
Grade 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 in the annealed condition.
Final heat treatment - annealing.
