TECHNICAL DATA SHEET - 1.4911
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) 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 - QT / solution treatment
