Hardfacing Electrodes

DIETHERME-HD

A hardfacing electrode depositing low hydrogen, low alloy steels weld metal for surfacing hammer dies. The weld metal possesses good toughness and resistance to heat for enhancing the life of the dies.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 250°C for one hour.

2. When welding on high hardenable materials of large thicknesses, adequate care for preheating, slow cooling & PWHT are necessary.

3. Use short arc and minimum weaving.
