{"id":37,"count":4,"description":"Welding electrode for 490 N\/mm\u00b2 high-tensile steel; ideal for strong, crack-resistant welding of high-strength structural steel.\r\n

The KOBELCO 490 N\/mm\u00b2<\/strong> series welding electrodes are specifically designed for welding high-strength structural steel. This product delivers joints that are tough, crack-resistant, and capable of withstanding heavy dynamic loads.<\/p>\r\n

High-tensile strength steels are widely used in bridges, pressure vessels, high-rise building structures, and medium- to high-pressure piping systems.<\/p>\r\n

Using a low-hydrogen basic coating, these electrodes produce a stable arc, deep weld penetration, and a clean weld bead free of porosity.<\/p>\r\n

Each variant is developed to suit the requirements of the welding position, plate thickness, and desired joint strength standards.<\/p>\r\n\r\n
