TS EN 14700 E Fe8
DIN 8555 E 3-UM-55-ST

Properties And Applications

Basic coated electrode for hardfacing of parts, subjected to high metal-to-metal wear, compression and impact at elevated temperatures. Due to it's Cr and Mo alloy content, has high mechanical strength, toughness and thermal resistance to operating temperatures up to 550° C. Especially designed for hardfacing of hot and cold cutting tools, hot shear blades, extrusion press pristons, forging dies, die cast moulds, glide and guiding surfaces. It provides a great advantage in the production, cladding and filling of sharp edges of new hot and cold cutting blades from the base metals with high tensile strength and proper alloying. Has excellent welding properties, a stable and regular metal flow, good weld bead appearance and very easy slag removal.
