Product name：KH-60-R
 
Classification：A5.13
 
 

  1. Weld metal is martensite structure with stable hardness but inferior toughness.
  2. It is difficult to be machined and cut.
  3. It provides excellent arc re-start, slag removal and bead appearance.
  4. It is suitable for severe metal-to-earth wear condition, such as repairing valve brackets, pump linings and blades.

 

Welding Instruction
  1. Dry the electrodes at 70-100°C for 30-60 minutes before use.
  2. Preheat temperature should be ≥ 200°C and PWHT should be 600°C.
  3. Use high tensile strength low hydrogen electrode for the buffer layer in multi-layer build-up and base metal with high hardenability.
