S31050 is a main alloy content of 25Cr-22Ni-3Mo Austenitic steel available in round bar, flat bar, plate, and forgings produced Specifications - ASTM A276
MATERIAL DATA SHEET - AISI 310MoLN & UNS S31050 & 2RE69
MATERIAL CATEGORY: 25Cr-22Ni-3Mo Austenitic steel
PRODUCT DESCRIPTION
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.
Final heat treatment - solution treatment / QT
MATERIAL SPECIFICATIONS - ASTM A959 (2004), A276, A312, A632, A176, A580
