NanoAlloy 395N
Unique NanoAlloy structure for unmatched abrasion and erosion resistance Produces tough uniform 67 HRC single and double pass weld deposits Wears like tungsten carbide at a fraction of the cost Outlasts chrome carbide and complex carbide alloys Ensures enhanced productivity and cost savings
NanoAlloy 395N - Cut your welding and maintenance costs
395N microstructure
X-ray diffraction (20 nm)
Single pass max. hardness
Low dilution weld profile
NanoAlloy technology for extraordinary weld deposit properties and superior wear resistance. DESCRIPTION: NanoAlloy 395N leads the newest generation of wear facing products based on the science and engineering of ultra-fine, submicron grain structures. Weld deposits have a high volume fraction of ultra-hard, complex borocarbides distributed in a matrix uniquely balanced between liquid and crystalline phases. Finely dispersed Nano-particles minimize wear of the underlying matrix by maximizing the complex borocarbides exposed at the wearing surface. 395N outperforms chromium and complex carbides by up to 40%! 395N’s wear resistance is equal to that of a 35% tungsten carbide alloy at a lower cost.

Stress relieving cracks Precision grindable deposits Smooth ripple-free weld surface
WELDING PARAMETERS: Preparation: Remove all “old” cracked or spalled material down to a sound base. Clean any residual oxides, coatings, spatter or residue. NanoAlloy 395N is not recommended for application beyond a 2 pass maximum. For steels with higher alloy content or which require build-up greater than ¼” a 2-pass buffer layer of Endotec DO*68S is strongly recommended. NANOALLOY 395N 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 head at a 70-80° angle from the workpeice and use a “pull” technique. For fully automated welding such as hardfacing cylindrical parts, the wire should exit at about a 10° leading angle from top dead center. Using this technique will assure a smooth and regular weld deposit profile with the optimum level of fusion. 395N can be used with or without shielding gas protection. Note: For best results apply NanoAlloy 395N with as little heat as possible, allowing parts to cool between layers. Finishing: For most applications, other than a superficial grind, finishing is not required. If some level of profiling is needed, grinding is recommended.
