NanoAlloys for Welding Wearfacing Applications
EnDOtec DO* 390N
Unique NanoAlloy structure for exceptional abrasion & erosion resistance. Ultra hard weld coatings with toughness. Hot hardness retained to red hot temperatures. Low friction coefďŹ cient for metal-to-metal wear resistance. User friendly for clean smooth welds.
New EnDOtec DO*390N
Patented NanoAlloys Extraordinary engineering material properties and service performance Advanced technology for enhanced productivity and cost savings Characteristics Slag-free flux-core wire electrode. Nanocrystalline structural composition with a high volume percentage of ultra-fine complex borocarbides in an iron matrix (mesomorphic structure).
Technical Advantages
Optimum service life results as a consequence of many years of research in the field of nanotechnology.
The DO*390N microstructures above show the high volume fraction of ultra-hard complex borocarbides uniformly distributed within a NanoAlloy iron alloy matrix. Such unique weld deposits have many practical features & benefits: Exceptional wear resistance to abrasion & erosion First layer hardness 70 HRC, second layer 71 HRC Retention of useful bulk hot hardness to 750°C Withstands repeated thermal cycles Low coefficient of friction without lubrication for metal to metal wear resistance Smooth ripple-free weld surface resistant to galling tribology Stress relieving cracks, grindable deposits Improved impact resistance over conventional ultra hard weld coatings
