Filler Metal ALLOY 59 is a nickel-chromium-molybdenum alloy with low carbon and silicon contents, is used for gas-tungsten-arc, gas-metal-arc, and submerged-arc welding (GTAW/GMAW/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.
