STAINLESS STEEL DATASHEET - UNS S31008
MATERIAL CATEGORY - 25Cr-22Ni Austenitic steel
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VD / 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 black/bright in the softened condition.
Final heat treatment - solution treatment / QT
