| Characteristics | CH-800M is a low hydrogen type electrode depositing weld metal of Molybdenum high speed steel. Weld metal shows stable hardness and excellent crack resistance. Hardness can be increased by Post-weld heat treatment. |
| Notes on usage | (1) Preheat the base metal at 300~500℃ to reduce a crack tendency, and cool slowly. (2) In the case of multi-layer build-up welding or welding mother plates with hardening property, under-lay with low hydrogen type electrodes for mild steel. (3) Dry the electrodes at 300~350℃ for 30~60 minutes before use. |
