Alloy 625

(UNS NO6625)

Nickel – chromium – molybdenum alloy with excellent resistance to a range of severely corrosive environment, particularly to pitting and crevice corrosion, and with high strength from cryogenic temperatures to around 980 C 0 (1500 F), and good oxidation-resistance at high temperatures. Application include chemical processing. marine and off shore engineering, pollution control, nuclear engineering and aerospace, Inconel alloy 625 has composition and `processing controlled to provide optimum resistance to low-cycle and 0 thermal fatigue at temperatures up to 650 C 0 (1200 F)
