TYPE
Basic coated, high Cromium-Niobium based hardfacing high recovery hardfacing electrode
APPLICATIONS
This electrode with a recovery of 190% can be used for overlays with extremely abrasive and sliding wear resistance, but with middle impact.
PROPERTIES
Due to the high Mo-content, abrasion resistance can be kept up to working temperatures of 600ºC ; the hardness is still 40-45 HRc at these temperatures. For hardfacing of more than 3 layers it is necessary to buffer with an electrode like DUR E 350 Kb that delivers a welding deposit of less hardness. Overlays on steel with high tensile strength have to be buffered with Croni 29/9 HL or 4370 HL.
Equivalent in FCAW: OA 64
SUITABLE FOR
Sugar mill knives and hammers, clinker crushers, sintering lines, fire gratings, mixer blades, gravel washing equipment, ceramic mixer blades, mill rollers, stone crushers, extruders etc….
