| Applications | Hard-surfacing of sprockets, tractor-link, idlers, crusher case etc. |
|---|---|
| Characteristics | CH-70K is a low hydrogen type electrode depositing weld metal of martensite structure. It is suitable for light impact abrasion and soil abrasion. It is difficult to do machining under the condition 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. |
