>Hard Facing
CH-80K
CH-80K deposits the weld metal of extremely hard martensite structure which containsdispersed precipitates of carbides and borides. It is applicable to such on abrasion thata weld metal of ordinary martensite structure can not withstand.Multi-layer hard-surfacing is not applicable due to less crack resistibility because thehardness of the weld metal is extremely high.Machining is impossible on the weld metal under as-welded condition.

| Applications | Hard-surfacing of cutter knives, shovel-teeth and casings. |

| Characteristics | CH-80K deposits the weld metal of extremely hard martensite structure which contains dispersed precipitates of carbides and borides. It is applicable to such on abrasion that a weld metal of ordinary martensite structure can not withstand. Multi-layer hard-surfacing is not applicable due to less crack resistibility because the hardness of the weld metal is extremely high. Machining is impossible on the weld metal under as-welded condition. |
| Notes on usage | (1) Preheat at 200℃ and over in general. (2) It is desirable to apply postweld heat treatment at about 600℃. (3) Under-layer welding with low hydrogen type electrodes for mild steel is needed. (4) Dry the electrodes at 300~350℃ for 30~60 minutes before use. |
