NONMAGNETIC AUSTENITIC STEEL - Grade GB Mn12Cr18NiSiN
MATERIAL CATEGORY - 18Cr - 12Mn Austenitic steel
The alloy is usually produced by AOD / VOD / EAF 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.
MATERIAL SPECIFICATIONS - GB/T 1268 by agreement.
