Filler Metal ALLOY 59 is a nickel-chromium-molybdenum alloy with low carbon and silicon contents, is used for submerged-arc welding (SAW). It offers excellent corrosion resistance, high mechanical strength and better thermal stability. Because of its low silicon and carbon contents and no tungsten, ALLOY 59 is no prone to grain-boundary precipitation during hot forming and welding.
APPLICATIONS: ALLOY 59 is well suited for welding in a wide variety of chemical processing facilities in both oxidizing and reducing media. This alloy is used to weld low-carbon-nickel-chromium-molybdenum alloys, for welding the clad side of joints in steel clad with low-carbon-nickel-chromium-molybdenum alloys, and for welding low-carbon-nickel-chromium-molybdenum alloys to steel and to other nickel-base alloys, such as alloys C-276, 22, 625 and other high alloys such as 6Mo stainless, 825 and even common grades of stainless steels. Some typical base metals that this alloy is used on are: ASTM S34565 (4565), NO8926 (22-25-6), S31254 (654SMO, 254SMO) and ASME B and SB 574, 575, 619, 622 and 626. This wire provides exceptional weldability and very low sensitivity to hot cracking.
