OK Autrod 13.22
GMAW
A copper-coated, low-alloyed 2.5% Cr, 1% Mo electrode for the GMAW of creep-resistant steels of the same type. Also for welding low-alloyed high tensile strength steels. OK Autrod 13.22 is usually welded with Ar/20CO2 as the shielding gas. The mechanical properties are given in the stress-relieved condition.
