SMAW Stick electrodes
Basic coated, high Cromium-Niobium based hardfacing high recovery hardfacing electrode
This electrode with a recovery of 190% can be used for overlays with extremely abrasive and sliding wear resistance, but with middle impact
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.
