TYPICAL APPLICATIONS
The alloy is usually produced by AOD / VOD /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 + Aged or Double aged.
FORMS AND SHAPES
Round bar (Diameter): 5.50 ~ 450mm
Square bar / Flat bar: 3 ~ 350mm
