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
TYPICAL APPLICATIONS
Superalloy is widely used to produce the high temperature components for gas turbine in the field of aviation, naval vessels and industry, such as turbine blade, guide blade, turbine disc, high pressure compressor disc, combustor, and also production of energy conversion devices, such as aerospace craft, rocket motor, nuclear reactor, petrochemical equipments, coaly transforming and so on.
