classification
AWS
A 5.28: ER 90S-B9
EN ISO
21952-A: W CrMo91
W.Nr.
1.4903
Applications
Designed for welding equivalent type 91~ 9% Cr Steels modified with small aditions of Niobium, Vanadium and Nitrogen to offer improved long term creep properties. This alloy
is specialy intended for high integrity structural service at elevated temperature such as: Headers, main steam piping and turbine casings, gasification plants etc.
