Application\/properties:<\/strong><\/p>\n\n\n\n

Low hydrogen basic electrode that has good weldability and the weld obtained from it has good mechanical properties, especially good toughness at low temperatures, and is resistant to cracking due to its high toughness at low  temperatures. This electrode is used for welding high strength steels used at low temperatures. The weld of this electrode has a greater penetration depth than that of E8018. The arc obtained from this electrode is stable and focused during welding. It also has good quality in terms of radiographic testing.<\/p>\n\n\n\n
