PRODUCT DESCRIPTION
The alloy is usually produced by EAF / VD / LF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied in the annealed, peeled bright condition.
Final heat treatment - Quenched and tempered.
