Properties and Applications

Hardfacing electrode for manufacturing and repair welding of turning and plaining chisels, reaming and shear blades, special spiral drills. Also suitable for manufacturing tools from unalloyed and low alloy steels and hardfacing the edges of cutting tools made of tool steel. Unalloyed and low alloy steels shall be preheated to 250-400°C before welding and postweld heat treatment at 400°C and then welded parts shall be cooled slowly. If buffer layer is needed, can be performed by EI 312 or EI 307B electrodes (max. 2,5 mm) and then hardfacing can be performed by EH 380 (max. 5 mm in heigth). Possible to use with DC, electrode in positive (+) pole and with AC.
