Description 1.4949 technical data sheet, 1.4949 heat treated peeled round bar, milled flat bar, plate, properties steelmaking, hot bloomed, forged, rolled
MATERIAL DATA SHEET - W-Nr.1.4949
MATERIAL CATEGORY - high temperature high strength steel and superalloy
PRODUCT DESCRIPTION
The alloy is usually produced by AOD & EAF & BEF 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 - heat treatment / QT / solution treatment
