KH-13M
Type of coating: Low hydrogen type
Weld metal remains a stable austenite structure even with air or water cooling after welding

Classification


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

Crusher hammers

Welding Position


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
