▎Applications and Features

  • 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.
  • It provides stable arc and almost no slag.
  • 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

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

▎Applications

It is suitable for repairing the parts of sintering factory, blast furnace, cement plant and agricultural machines in severe earth abrasion.
