DAIKOFCW 625P

Engineered to replicate the composition of alloy 625, this consumable is widely recognized for its exceptional resistance to general corrosion, pitting, crevice, and stress corrosion cracking, especially in challenging chloride environments. Elevated levels of Cr, Mo, and Nb contribute to its remarkable performance, endowing it with unparalleled strength that surpasses standard nickel-base alloys. With a broad operational range spanning from –269°C to above 1000°C, it is well-suited for welding heat-resistant alloys like Inconel 601, Incoloy 800/800H, or their combinations with other alloys, catering to various applications in furnace equipment, petrochemical plants, and power generation facilities. This consumable is versatile for performing overmatching corrosion-resistant welds in alloy 825, Hastelloys G and G3, alloy 28, 904L, and the 6%Mo superaustenitic stainless steel 254SMo.Additionally, it is employed for overlays on pumps, valves, and shafts, particularly in demanding offshore and marine environments where high pitting resistance (PRE = 50) and tolerance to dilution are imperative. In welding high-strength ferrous alloys, including cryogenic 9% nickel steels, and for the reclamation of dies demanding rapid work-hardening and toughness, this consumable stands as a preferred choice. Notably, no preheat is required, and the maximum interpass temperature is set at 250°C. For superaustenitic alloys, the interpass temperature should be rigorously controlled, not exceeding 100°C.
