ALLOY STEEL DATA SHEET - ASTM XM-19
MATERIAL CATEGORY: 22Cr-12Ni-5Mn Austenitic steel
The alloy is usually produced by BEF + AOD 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 black/bright in the softened condition.
Final heat treatment - solution treatment / QT
ASTM A959 (2004), A276, A312
Black bar / Flat bar / Steel strip / Square bar
Bright - peeled + polishing, centerless grinding
Forged - ring, tube, pipe casing, discs, shaft
