| Product name：KH-13M |
| Classification：A5.13 |
  |
- 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 |
||||||||
|
(1) Dry the electrodes at 300-350°C for 30-60 minutes before use. (2) 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). (3) The old hardfacing layer should be gouged first. Cracks are beveled by carbon cutting electrode and repaired by KS-309 before welding with KH |
