▎Applications and Features

  • Weld metal contains the carbide precipitates of Cr, Mo, and V.
  • It is unable to be machined and cut.
  • It provides excellent weldability, heat resistance and impact toughness.
  • It is suitable for repairing forging molds.

▎Welding Instruction

  • Dry the electrodes at 200-250°C for 30-60 minutes before use.
  • Preheat temperature should be ≥ 200°C and PWHT should be 600°C.
  • Use high tensile strength low hydrogen electrode for the buffer layer in multi-layer build-up and base metal with high hardenability

▎Applications

It is suitable for repairing forging molds.
