JIS Z3251 DF3C-600-B
Notes on Usage
Welding Positions:
① Preheat at 150℃(302℉) or more than that in general.
② Postheat at about 600℃(1112℉), if possible.
③ In case of multi-layer build-up welding or welding base metal of hardening property, underlay
with low hydrogen type carbon steel electrodes.
④ Dry the electrodes at 350~400℃(662~752℉) for 60 minutes before use.
Applications
JIS Z3251 DF3C-600-B For soil abrasion. Hardfacing of cutting knives and casings.
Characteristics on Usage
JIS Z3251 DF3C-600-B is an electrode depositing weld metal of martensite . This electrode, all-weld metal of very hard martensite structure containing small quantity of austenite structure. Machining is impossible “as welded”. It is mostly suitable for soil abrasion.
