OK 48.00 is a basic, low-hydrogen electrode for welding unalloyed, carbon-manganese and fine-grained steels. The electrode produces tough and crack-resistant weld metal and, thanks to its moisture-resistant coating (H4R), is suitable for structures subject to high loads and critical stress conditions. The stable arc, good penetration and high welding speed when welding vertically upwards make OK 48.00 a widely used electrode for demanding applications.
OK 48.00 is used for steel structures, bridges, pressure vessels, shipbuilding and other critical structural works where a reliable welded joint with high toughness and low hydrogen content is required.
