classification
AWS
A 5.28: ER 90S-B3
EN ISO
21952-B: W 2C1M
Applications

TIG/GTAW filler metal for high temperature creep resistant 2.25%Cr1%Mo ferritic steel. These steels are used for creep resisting applications up to ~600°C. Typical applications in power generation plant include steam piping, turbines and boilers; the alloy also finds applications in the chemical and petro-chemical industries.
