OK 76.28 SUPPLIER
OK 76.28L is a basic coated hydrogen controlled iron powder type electrode, depositing a weld metal of the type 2.25Cr-1Mo, suitable for welding of similar Cr-Mo steels, used in high temperature components of power plants, boilers, oil-refineries, petrochemical plants etc. The slag system is designed to give a stable arc and minimum spatter. The weld metal provides scaling resistance up to 600°C.
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 covered 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.
