MATERIAL CATEGORY
High temperature high strength steel and superalloy
PRODUCT DESCRIPTION
The alloy is usually produced by AOD/VIM/VOD followed by electroslag refining (ESR) or VAR 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 bright in the solution annealing condition.
Final heat treatment - heat treatment / QT / solution treatment
