D620 is a submerged arc surfacing welding wire. The surfacing welding wire has excellent welding process performance, beautiful appearance and easy slag removal.
D620 cement extrusion roll surfacing welding wire:
埋弧堆焊药芯焊丝，焊接工艺性能优良，成形美观，脱渣容易。 Note: Submerged arc surfacing flux-cored wire has excellent welding process performance, beautiful appearance and easy slag removal. The metal of the surfacing layer is a low-carbon alloy of chromium and tungsten, which has a precipitation strengthening effect. Disperse carbides are precipitated at high temperatures, which can maintain good high-temperature strength and hardness, so it has excellent tempering resistance and wear resistance.
用于堆焊破碎机对辊、水泥挤压辊、热轧开坯辊等。 Uses: Used for overlay roll of crusher, cement extrusion roll, hot-rolled billet roll, etc. Requirements, surfacing welding more than 4 layers.
