NanoAlloy® technology for extraordinary amorphous (glass-phase) weld deposit properties and superior wear resistance. DESCRIPTION: Nanoalloy 395N is the newest development in cored wire technology. A new generation of wearfacing products based on the science and engineering of ultra-fine, submicron grain structures. Weld deposits have a high volume fraction of ultrahard borocarbides distributed in a mesomorphous* iron-alloy matrix. A transformation phase relating to, or existing in, a state of matter typically intermediate between a liquid and a crystal phase i.e. not fully crystalline or fully amorphous. Nanoalloy 395N weld deposits present a crystalline microstructure with nano-size crystals and high hardness carbides evenly spread throughout the matrix. The most important characteristic of 395N is that it provides high hardness within a ductile matrix resistant to moderate impact.

TECHNICAL ADVANTAGES: The unique NanoAlloy® type microstructure ensures exceptional performance against wear by severe abrasion, erosion combined with moderate impact from ambient to elevated service temperatures. Easy striking and restriking for anti-wear patterns High efficiency metal recovery Single pass attains close to maximum hardness First layer hardness 68 HRC, second layer 70 HRC
Withstands thermal cycling Low friction coefficient without lubrication for metal to metal wear resistance Retains high hardness properties at elevated temperatures
Stress relieving cracks Precision grindable deposits Low dilution with base metal Smooth ripple-free weld surface resistant to galling
WELDING PARAMETERS: Preparation: Higher carbon steels up to 0.40% carbon should be preheated in the range of 350-500°F (177-260° C). NOTE: High-end carbon steels should use a butttering pass of XHD 6868 or similar product. When welding manganese steel castings directly, or steels with a high hardenability, TeroMatec 688OA or 690OA offer an ideal cushion layer to further optimize the wear resistance of 395N. DO NOT WELD DIRECTLY ON MANGANESE STEELS, WILL NOT BOND! NOTE: Higher preheats up to 600°F (315°C) will reduce microfissuring. Welding Technique: As indicated in the parameters, there are certain advantages in using either a “push” or “pull” method during welding. For most downhand welding the pull method is suggested with the wire positioned at a 70°-80° angle. This will provide a clean, virtually spatter-free, high-crowned weld deposit. 395N can be utilized as an open arc wire requiring no shielding gas.

Flow Rates: 30-35 SCFH (15-17 L/min.) Typical Coverage: 5.5lbs will cover 1 sq.ft. x 1/8” thick Note 1 - MIG or Open Arc: Nanoalloy 395 N wire works very well with or without shielding gas. When using extended welding parameters the shielding gas helps reduce heat build up in the welding gun assembly.
APPLICATIONS: Designed for protective coatings with extreme resistance to abrasion, erosion combined with moderate shock on carbon, alloy, stainless and cast steels. APPLICATIONS
