Characteristics | CH-80 is a low hydrogen type electrode depositing weld metal of uniform martensite structure. It is suitable for soil abrasion. Machining is not applicable as welded. |
Notes on usage | (1) Preheat at 150℃ and over in general. (2) It is desirable to postheat at about 600℃ (3) In case of multi-layer build-up welding or welding mother plates with hardening property, under-lay with low hydrogen type electrodes for mild steel. (4) Dry the electrodes at 300~350℃ for 30~60 minutes before use. |
