CORODUR® E 67
CLASSIFICATION
DIN EN 14700
E Fe16
GENERAL CHARACTERISTICS
Thickly coated, AC - weldable high efficiency electrode with approx. 170 % recovery. The weld metal deposited by CORODUR E 67 is of ledeburitic structure. The alloy is highly resistant to abrasion combined with impact stress. The special chemical composition of the alloy ensures good wear resistance in various temperature ranges. The fine-grained structure of the weld metal provides a solid matrix which retains the vanadium carbides also when subject to strong abrasion and ensures high crack-resistance. Smooth fusion, almost slag-free welding deposit. A buffer layer of CORODUR E 200 K is recommended prior to surfacing on old hardfacing.
APPLICATION
Hardfacing on conveyor worms, clinker crushers, grates in mineral dressing equipment, concrete and cement pumps, etc.
