OK Autrod 13.91
GMAW

A copper-coated, low-alloyed electrode for gas metal arc hardfacing when a highly wear-resistant weld metal is required. Due to the high Cr content, about 9%, the weld metal displays relatively good resistance to general corrosion. The weld metal is resistant to softening up to about 550°C. Used for hardening for example loading machines, road machines, mixers, shovel teeth, different tools and wear parts. OK Autrod 13.91 can be welded with Ar/20CO2 or pure CO2 as the shielding gas.
