DESCRIPTION:Nanoalloy 395 N is the newest development in cored wiretechnology. A new generation of wearfacing products basedon the science and engineering of ultra-fine, submicrongrain structures. Weld deposits have a high volume fractionof ultra-hard borocarbides distributed in a mesomorphous*iron-alloy matrix. A transformation phase relating to, orexisting in, a state of matter typically intermediate betweena liquid and a crystal phase i.e. not fully crystalline orfully amorphous.Nanoalloy 395 N weld deposits present a crystalline microstructurewith nano-size crystals and high hardness carbidesevenly spread throughout the matrix.The most important characteristic of 395 N is that it provideshigh hardness within a ductile matrix resistant tomoderate impact.TECHNICAL DATA:Operating Conditions:Current Type: ..............................................DCEP (+)Voltage: .........................................................25-34Amperage: ...................................................170-300Wire Stick-Out (MIG): ..............................1/2” - 3/4”Wire Stick-Out (Open Arc): ...................1” - 1 1/4”Typical Mechanical Values:Typical Hardness 1st Pass: ....................68-70 HRCTypical Hardness 2nd Pass: ...................69-71 HRCTemperature Limit ...................................1,400°F (760°C)Carbide Type: Complex borocarbide matrix of sub-micron,near-nano scale microstructureParameters:Position: Pull TechniqueShielding Gasses:a. Recommended gas mixture: 98% Ar + 2% O2b. Alternative gas mixture: 75%Ar + 25% CO290%Ar + 10%CO2Flow Rates: 30-35 SCFH (15-17 L/min.)Typical Coverage: 5.5lbs will cover 1 sq.ft. x 1/8” thickNote 1 - MIG or Open Arc: Nanoalloy 395 N wire works very well with or without shieldinggas. When using extended welding parameters the shielding gas helps reduceheat build up in the welding gun assembly.Availability:Package: 33 lb coils (15 kg)Wire Diameter: 0.045“ (1.2mm), 1/16“ (1.6mm)PROCEDURE AND TECHNIQUE:Power-Source Type: Nanoalloy 395 N is compatible withmost conventional constant voltage/constant potential(CC/CV) power sources, including programmable & pulsedarcunits. Note: Integrated wire feeders should be set upwith a 4-roll, knurled-drive wire system, and the gun cableliner, with either a Teflon® or polyamide liner to reduce wiredrag.Base Metal Preparation: Parts to be welded should be freeof oil or grease. For optimum results a light grind to removescale or other surface contamination, is advised. Alsoeliminate any previous weld metal and fatigued metal bymechanical means. Base material such as carbon steels,alloy steels, cast iron, and stainless steels can be weldedwith this product.Preheating Guide: The carbon and alloy content of thepart to be welded normally dictates preheating levels.The ease at which a part air-hardens (air-hardenability) isanother critical point along with considerations of workpiece size, thickness, and shape. Preheating according tocarbon contents of metal and thickness and configurationof the part to be welded. For a total carbon equivalent werecommend:• Up to 0.25%C: It is not necessary to preheat• From 0.25% to 0.45%C: Preheat to 200° - 400°F (100° - 200°C)• From 0.45% to 0.8%C: Preheat to 400° - 660°F (200° - 350°C)Buffer Layer Guide: To minimize any microfissuring tendencies,the use of an underlay is often a practical advantage.When welding manganese steel castings, or steelswith a high hardenability, TeroMatec 688OA or 690OA offeran ideal cushion layer to further optimize the wear resistanceof 395 N.Welding Technique: As indicated in the parameters, thereare certain advantages in using either a “push” or “pull”method during welding. For most downhand welding thepull method is suggested with the wire positioned at a 70°-80° angle. This will provide a clean, virtually spatter-free,high-crowned weld deposit. 395 N can be utilized as anopen arc wire requiring no shielding gas.Note - If a second pass is required it should follow while the weld metal is still hot.TYPICAL APPLICATIONS:• Bucket teeth • Extruders • Fans• Mixers • Bark crushers • Hammers• Scrapers • Knives • Central blades• Sinter crushers • Milling rolls• Milling liners • Conveyor screws• Coal crushers • Pipes and elbowsYOUR RESOURCE FOR PROTECTION, REPAIR AND JOINING SOLUTIONSEutectic CorporationN94 W14355 Garwin Mace DriveMenomonee Falls, WI 53051 USAP 800-558-8524 • F 262-255-5542www.eutecticusa.comEutectic Canada428, rue Aime VincentVaudreuil-Dorion, Quebec J7V 5V5Phone: (800) 361-9439Fax: (514) 695-8793www.eutectic-na.comEutectic MexicoKM 36.5 AutopistaMexico-Quertaro54730 Cautitlan-IzcalliEstado de Mexico, MexicoPhone: 011 (52) 55-5872-1111e-mail: eutectic.mexico@eutectic.com.mxStatement of Liability: Due to variations inherent in specifi c applications, the technical information contained herein, including any information as to suggested product applications orresults, is presented without representation or warranty, expressed or implied.
