Böhler FOX CN 13/4 stick electrodes

Böhler FOX CN 13/4 is a basic-coated, high-alloy stainless, soft-martensitic electrode for corrosion-resistant welding of martensitic-ferritic rolled, forged, and cast parts. The weld metal has the lowest hydrogen content (HD < 5 ml/100 g) and offers maximum crack resistance combined with excellent elongation and toughness properties.
