KH-50N-1
Type of coating: Lime titania type
Weld metal is martensite structure with 13%Cr

Classification


Application and Features 

• Weld metal is martensite structure with 13%Cr
• It provides stable hardness, excellent corrosion resistance and acid resistance
• KH-50N-1 has better thermal fatigue and crack resistance than KH-50 due to the addition of Ni and Mo. The abrasion resistance at high temperature is outstanding
• It is suitable for repairing molds, steel wheels, agitator blades and hot rolling rollers

Hot rolling roller

Welding Position


Welding Instruction

• Dry the electrodes at 200-250°C for 30-60 minutes before use.
• Clean up the contaminations on the work piece. Keep arc as short as possible.
• Preheat temperature should be above 150°C for repairing low alloy steel or medium/high carbon steel

Application
- It is suitable for repairing molds, steel wheels, agitator blades and hot rolling rollers
