Xuper 680 CGS Tool Steel Electrode

• Composition Characteristics: A high-alloy manual electrode with deposited metal rich in Fe, Cr, and Ni alloys, featuring an austenitic structure strengthened by δ-ferrite.
• Performance Advantages:
  • Excellent Crack Resistance: Forms high-strength joints with outstanding resistance to cracking, corrosion, and oxidation.
  • High Dilution Tolerance: Suitable for use on various steels with strong adaptability to different steel types.
  • Superior Welding Process: Special rutile-basic coating facilitates easy welding with spray-type metal transfer, applicable to all steels. Easy arc initiation and re-ignition with low welding current.
  • Optimal Microstructure Properties: CGS controlled grain size structure ensures strength and ductility.
• Application Scope: Suitable for welding dissimilar steels, high-carbon steels, and hard-to-weld steels such as cast steel, heat-treated steel, high-carbon steel, manganese steel, stainless steel, tool steel, and steels with unknown composition. Also used for dissimilar steel connections, tool and mold repair, gear tooth restoration, machine casing crack repair, hardfacing and repair of earthmoving and drilling equipment, and worn shaft repair.
• Welding Process: Generally requires no preheating; preheating depends on the carbon equivalent of the steel, workpiece size, thickness, and geometry. For steels with carbon equivalent CE < 0.2, preheating is usually unnecessary; for CE between 0.2-0.4, preheat at 100-200°C; for CE between 0.4-0.8, preheat at 200-350°C. However, 12%-14% manganese steel must never be preheated, and workpiece temperature should be kept below 250°C during welding. Welding current is selected based on electrode diameter: 45-85A for 2.5mm, 60-110A for 3.2mm, 90-150A for 4.0mm, and 145-200A for 5.0mm. Minimize arc length during welding, keep interpass temperature below 300°C, remove slag before each new pass, use DC reverse polarity (DCEP). Post-weld heat treatment is generally not required; adjust cooling rate based on base material and workpiece size.

N9080 Cobalt-Based Hardfacing Electrode 2

• Composition Characteristics: A cobalt-based electrode containing chromium, nickel, molybdenum, manganese, and other elements.
• Performance Advantages:
  • Excellent Heat Resistance: Superior heat resistance with thermal resistance up to 1000°C, good creep resistance, and minimal structural deformation.
  • Low Friction Coefficient: Low friction coefficient for metal/metal sliding performance.
  • Strong Work Hardening: Work hardening rate up to over 60%, with good tempering toughness.
  • Good Corrosion Resistance: Strong resistance to chemical corrosion, high crack resistance, and easy machinability with standard tools after welding.
• Application Scope: Mainly used for medium-carbon, quenched, and air-hardened steels, alloy steels, manganese steels, and nickel alloys.
