DAIKOWS 59

Designed to match the alloy 59, the weld deposit proudly showcases a precise composition of 59% Ni, 23% Cr, and 16% Mo. Alloy 59 surpasses alloys C276 and C4 in performance across a broader range of oxidizing environments, thanks to its elevated molybdenum content. With an increase in chromium to 23%, alloy 59 exceeds alloy C22 in cumulative alloying levels, making it apt for welding this specific alloy group. Beyond this primary role, alloy 59 consumables deliver resilient and durable Nb-free weld metal, making them well-suited for dissimilar welds involving superaustenitic and superduplex stainless steels or combinations with nickel base alloys. Applications of alloy 59 in highly corrosive environments span diverse industries, including scrubbers for flue gas desulphurization (FGD), digesters, papermaking equipment, chemical process plants, corrosion-resistant overlays, and challenging offshore and petrochemical settings. The consumable eliminates the need for preheating, with recommended heat input below 1 kJ/mm and an interpass temperature capped at 100°C, to minimize precipitates that could compromise the corrosion resistance and ductility of the weld metal.
