High HRC 65-67 Hardfacing Rod Welding Electrode Efe1

The AWS A5.13 EFe1 is a typical iron base hardfacing electrode. It has a pearlitic structure, which results from low carbon and low amounts of other alloying elements. The EFe1 electrodes are mainly used for buildup overlays and restoration of carbon steel and low alloy steel machinery parts in hardfacing applications. It has high impact resistance and relatively low hardness, as well as excellent weldability. The buildup overlays may only provide mild resistance to wear. Its main function is to return a worn part back to or near, its original dimensions and to provide adequate support for subsequent layers of true hardfacing materials.
