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.
