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 550C. 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.
