Properties and Applications

Heavy coated, high recovery (170%) surfacing and hard surfacing electrode which gives Nickel-Chromium-Molibdenum alloy weld metal. Weld metal is resistant to abrasion, impact, corrosion and high temperatures. Especially used in welding of hot-work press tools which are subjected to above service conditions. Suitable to use inmaintenance welding of hot-work press tools and hammers, forging and extrusion dies and parts, pressure casting pistons and dies, rolling rolls, hot-stripping tools, pump rotors and valves. Preheating to 400-500°C is required, depending on the size, shape and chemical analysis of the part to be welded. Has a stable arc, smooth weld bead surface and weld metal is free of cracks and porosity. Welding shall be performed with short stick-out distance, perpendicular to base metal and craters shall be filled well. Preferred to use with DC, electrode in positive (+) and possible to use also in AC.
