21952-B G 1CM
MIG/GMAW wire for high temperature creep resistant 1.25%Cr-0.5%Mo ferritic steels, 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.
For matching 1.25%Cr-0.5%Mo creep resisting ferritic steels.
