ED-SG CrMo2
MIG (GMAW) wires for creep resisting steels

Classification DIN EN ISO

21952-A G CrMo2Si

Material No.

1.7384

Classification AWS

A5.28 ER90S-G

Approvals

TÜV 10966, CE, DB 42.045.20

Characteristics and application

MIG/GMAW wire for high temperature creep resistant 2.25%Cr-1%Mo ferritic steels, i.e. P21/P22. 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. The wire has low levels of tramp elements (eg. Sn, As, Sb and P) providing a low Bruscato Factor (X< 10 ppm) for temper embrittlement resistant applications.
