OK FLUX 281
OK Flux 281 flux is an active bonded flux designed for high speed, single pass welds, especially utilized in the boiler tube and metal building fabrication industries.
Features
OK Flux 281 is intended for welding gauge thickness and thin steel plate(up to 3/8 in. thick) for butt, lap and fillet welds. Due to the excellent operating characteristics, quality welds with self-peeling slag and free from undercut may be achieved with welding speeds ranging from 50 to 100 inches per minute.
*Single pass application only. Any mechanical property and undiluted weld chemistry listed are for information only.*
