DESCRIPTION:

NanoAlloy 390N leads the newest generation of wearfacing products based on the science and engineering of ultra-fi ne,nano-sized grain structures. Weld deposits have a high volume fraction of ultra-hard, complex borocarbides distributed ina matrix uniquely balanced between liquid and crystalline phases.

Crushed Tungsten Carbide Cast Tungsten Carbide NanoAlloy 390N

With about a third the density of tungsten carbide, the wear resistance of NanoAlloy 390N surpasses its nearest competitionin total mass lost on abrasion resistance ASTM G65 tests. Combined with the advantages of fi nely dispersed, nano-sizeparticles, this means the same deposit size of NanoAlloy 390N lasts longer than conventional Tungsten Carbide based alloys!

WELDING PARAMETERS:

Preparation: Remove all “old” cracked or spalled material down to a sound base. Clean any residual oxides, coatings, spat-ter or residue. NanoAlloy 390N is not recommended for application beyond a 2 pass maximum. For steels with higher alloycontent or which require build-up greater than ¼” a 2-pass buffer layer of Endotec DO*68S is strongly recommended.

NANOALLOY 390N SHOULD NOT BE USED ON MANGANESE/HADFIELD STEELS AS IT WILL NOT BOND!

Welding Technique: After checking that the welding conditions are optimal by testing on scrap metal, position the gun headat a 70-80° angle from the workpiece and use a “pull” technique. For fully automated welding such as hardfacing cylindricalparts, the wire should exit at about a 10° leading angle from top dead center. Using this technique will assure a smooth andregular weld deposit profi le with the optimum level of fusion. 390N can be used with or without shielding gas protection.

Note: For best results apply NanoAlloy 390N with as little heat as possible, allowing parts to cool between layers.

Finishing: For most applications, other than a superfi cial grind, fi nishing is not required. If some level of profi ling is needed,grinding is recommended.
