OK Tigrod 13.22
GTAW
A copper-coated, low-alloyed, 2.5% Cr, 1% Mo rod for the GTAW of creep-resistant steels of the same type. Also for welding low-alloyed high tensile strength steels. OK Tigrod 13.22 is normally welded with pure Ar as the shielding gas. The mechanical properties are given in the stress-relieved condition.
