JIS Z3251 DF2B-500-B
Notes on Usage
Welding Positions:
① Preheat at 150℃(302℉) and more than that in general.
② In case of multi-layer build-up welding or welding base metal of hardening property, underlay
with low hydrogen type carbon steel electrodes.
③ Pay attention to blow hole at the arc starting.
④ Dry the electrodes at 350~400℃(662~752℉) for 60 minutes before use.
Applications
JIS Z3251 DF2B-500-B For intermetallic abrasion and light soil abrasion. Hardfacing of idlers and truck links.
Characteristics on Usage
JIS Z3251 DF2B-500-B is an electrode designed for putting prime importance on hardness, but not neglecting toughness. Machining is difficult. The welds become passably mild with gradual cooling after
welding. It is suitable for heavy duty intermetallic abrasion and light impact abrasion.
