Approvals

TÜV 07300, CE

Characteristics and application

TIG/GTAW rod for high temperature creep resistant 2.25%Cr-1%Mo ferritic steel, 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.
