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 bright surface in the solution annealed condition.
Final heat treatment - solution treated + Aged.
