PRODUCT DESCRIPTION
18Cr12MoVNbN is usually produced by EAF / BEF followed by electro-slag 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 in the annealed, peeled condition.
Final heat treatment - quenched and tempered + SRA.
