OK Autrod 13.12
GMAW

A copper-coated, low-alloyed, 1% Cr, 0.5% Mo electrode for the GMAW of creep-resistant steels of the same type and other low-alloyed high tensile strength steels. OK Autrod 13.12 is usually welded with Ar/20CO2 as the shielding gas. The mechanical properties are given in the stress-relieved condition.
