Hardfacing Electrodes
ES 65 GRZ / EN 14700: E Fe 16
Description
ES 65 GRZ Super hardfacing electrode with very high contents of carbide forms ( Mo,V,W,Nb )for deposits subject to extreme sliding mineral abrasion. Outstendingly suitable for deposits on weldments expected to withstand severe abrasion under high temperature stress. Typical applications include hardfacing on earth moving equipment and on wearing parts in the cement and brick making industries as well as on fire grate bars and fire grate teeth in the magnesite and iron & steel industry. Re-drying 300-350ºC /min. 2 h.
