Product name：KH-CRX
 
Classification：A5.13 / EFeCr-E4
 
 

  1. Weld metal contains complex carbide precipitates of Cr, Nb, Mo, W, and V. It has the best resistance to high temperature abrasion and earth abrasion. The abrasion resistance is exceptional in high temperature corrosive conditions.
  2. It provides stable arc and almost no slag.
  3. The service temperature can be up to 650°C. It is suitable for repairing the parts of sintering factory, blast furnace, cement plant and agricultural machines in severe earth abrasion.

 

Welding Instruction
  1. Dry the electrodes at 100-200°C for 30-60 minutes before use.
  2. Preheat temperature should be ≥ 250°C and PWHT should be 600°C.
  3. Weld beads should be put down in grid shape to prevent the surfacing layers from spalling.
