Product description

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. Typical Applications: Due to its high hardness, wear resistance, and mechanical strength, it is highly suitable for build-up and hardfacing of lathe tools, planer blades, milling cutters, spiral drill bits, cold cutting tools, and cutting edges of tools made from high-speed steel.
