Application and Features
- Weld metal remains a stable austenite structure even with air or water cooling after welding
- It provides good resistance to abrasion accompanied by heavy impact and good toughness. However, it is not resistant to abrasive wear
- It is suitable for repairing constructions, mining, railroads and steel mills
- It is ideal for melt-in fusion and welding of high manganese steel

Welding Instruction
- Dry the electrodes at 300-350°C for 30-60 minutes before use
- Take skip welding method to prevent the embrittlement because the local overheat (above 260°C) causes the carbides to precipitate. The weld bead should not exceed 20mm (W) × 5mm (T) × 100mm (L)
- The old hardfacing layer should be gouged first. Cracks are beveled by carbon cutting electrode and repaired by KS-309 before welding with KH-13M
Application
- It is ideal for melt-in fusion and welding of high manganese steel
