Finox 4370 AC is an electrode for joint welding of unalloyed and low-alloyed steels with high-alloyed steel, cast steel types and for austenite-ferrite-joints at working temperatures of up to 300 °C. This stick electrode is suited for welding of difficult-to-weld steel with high carbon content as well as austenitic manganese steel, for buffering layers and for wear-resistant surfacing when exposed to work-hardening shock, pressure and rolling load. The weld metal is fully austenitic, corrosion-resistant, scale-resistant up to 850 °C and can be work-hardened up to a hardness of 350 HB.
