DAIKO 112

Designed with an optimized composition for the alloy 625, this subfamily is particularly indicated for resisting general corrosion, pitting, crevice corrosion, and stress corrosion cracking in chlorine-rich environments. These features result from high levels of Cr, Mo, and Nb, which not only provide superior mechanical strength but also position this alloy at the top of standard nickel-based alloys. Its properties are maintained over a wide range of temperatures, from -269 °C to over 1000 °C. This alloy is also ideal for welding heat-resistant alloys such as Inconel 601, Incoloy 800/800H, and their combinations with other alloys, typically used in furnace equipment, petrochemical plants, and power plants. Additional applications include: corrosion-resistant weld overlays for alloys such as 825, Hastelloys G and G3, alloy 28, 904L, and superaustenitic stainless steel 6%Mo 254SMo. It is also used for overlays on pumps, valves, and shafts, especially in offshore and marine environments where high pitting resistance (PRE = 50) and good tolerance to dilution are crucial. Perfect for welding on high-strength ferrous alloys, including 9% nickel cryogenic steels, and for refurbishing matrices requiring rapid hardening and robustness. No preheating is required, and the maximum allowed interpass temperature is 250 °C. As for superaustenitic alloys, the interpass temperature must be maintained at a maximum of 100 °C.
