Product name:KH-50N-1
 
Classification:A5.13
 
 

  1. Weld metal is martensite structure with 13%Cr.
  2. It provides stable hardness, excellent corrosion resistance and acid resistance.
  3. 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.
  4. It is suitable for repairing molds, steel wheels, agitator blades and hot rolling rollers.

 

Welding Instruction

(1) Dry the electrodes at 200-250°C for 30-60 minutes before use.

(2) Clean up the contaminations on the work piece. Keep arc as short as possible.

(3) Preheat temperature should be above 150°C for repairing low alloy steel or medium/high carbon steel.
