OK 73.68 SUPPLIER
OK 73.68 is a 2.5Ni alloyed hydrogen controlled electrode, specially designed for welding low alloy steels used for high ductility, toughness and resistance to the embrittlement effects at sub-zero temperatures. The weld metal is suitable for impact requirements down to -60°C. The composition of the weld metal is designed for good low temperature impact properties, even when welding vertically up. The alloy is also noted for its good corrosion resistance to sea water and sulphuric acid fumes.
Features & Benefits
Welding Invented
When our founder Oscar Kjellberg developed the world’s first coated welding electrode in 1904, he launched a company whose innovation and uncompromising standards have helped create the history of welding itself. This legacy continues in the quality, performance, and continuous development of the mild steel welding electrodes we make today.
Factory Fresh Low Alloy Electrodes, Straight from the Pack
ESAB’s VacPac™ packaging is hermetically sealed and vacuum-packed to protect low alloy electrodes from moisture pick up and re-absorption from the air. Electrodes can be used straight from the package without the need to re-bake them or you can store them temporarily in holding ovens and quivers. Get fresh, dry low alloy covered electrodes every time with ESAB.
