ESAB KV4 SUPPLIER
ESAB KV4 is a 5Cr-0.5Mo alloyed basic coated low hydrogen electrode, used for welding creep resistant Cr-Mo bearing steels. It deposits a weld metal that is highly resistant to heat and corrosion. The electrode is designed to provide a stable arc, minimum spatter and superior weld bead. ESAB KV4 finds extensive use in the oil refineries, chemical and petrochemical Industries where it has to resist corrosion and hydrogen attack at high temperatures.
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.
