OK Autrod 13.09
GMAW
A copper-coated, low-alloyed, 0.5%Mo electrode for the GMAW of creep-resistant steels of the same type, such as pipes in pressure vessels and boilers with a working temperature of up to about 500°C. It can also be used for welding low-alloyed high tensile strength steels. OK Autrod 13.09 is usually welded with Ar/20 CO2 as the shielding gas. The mechanical properties are given in the stress-relieved condition.
