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. Has a stable arc and weld metal is free of cracks and porosity. So, E 717 H electrode is also suitable for crack-free welding of parts which are subjected to severe thermal stress and chemical attack. Suitable to use in welding hot-work press tools, forge dies, hot-stripping tools, pump rotors, valves. Preferred to use with DC, electrode in positive (+) and possible to use also with AC. Preheating to 400-500˚C is required, depending on the size, shape and chemical analysis of the part to be welded. Welding shall be performed with short stick-out distance, perpendicular to base metal and craters shall be filled well.
