WSG CrMo 1

TIG welding rods for creep resisting steel

Quality WSG CrMo 1
Classification DIN EN ISO 21952-A W CrMo1Si
Material No. 1.7339
Classification AWS A5.28 ER80S-G
Approvals TÜV 04293, CE, DB 42.045.13
Characteristics and application TIG/GTAW rod for high temperature creep resistant 1.25%Cr0.5%Mo ferritic steel, i.e. P11/P12. These steels are used for creep resisting applications up to ~550°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.
Base materials For matching 1.25%Cr0.5%Mo creep resisting ferritic steels.
