Product name：KH-50MN
 
Classification：A5.13
 
 

  1. Weld metal is martensite structure with 13%Cr and 5%Mn.
  2. It is difficult to be machined and cut.
  3. It provides excellent heat, corrosion and abrasion resistance. It is suitable for metal-to-metal wear; metal-to-earth wear and high temperature wear condition.
  4. It is suitable for repairing agitator blades and heat exchanger wings.

 

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