Mo: 6 Nb: 6,2 |
The electrode is used for hardfacing of parts subject to strong abrasive | |||||
HRC: 63-65 | W: 2 V: 1 |
wear, friction also at high temperatures.CARBODUR 65 provides extremly | ||||

Heavy coated high efficiency hardfacing electrode with 170% recovery. | |||
Si: 1,5 V: 10 |
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 | ||||||
HRC: 63-66 |
metal provides a solid matrix which retains the vanadium carbides also | |||||
