Alloy 625 (UNS N06625) is an austenitic nickel base superalloy possessing excellent resistance to oxidation and corrosion over a broad range of corrosive conditions. Even temperature to 1100 degree C, alloy 625 also has exceptional fatigue resistance.
The material possesses a high degree of formability and shows better weldability than many highly nickel-base alloys. The alloy is resistant to intergranular corosion even in the welded condition.

Corrosion and Oxidation Resistance:
> The high level of chromium and molybdenum in Alloy 625 provides a high level of pitting and crevice corrosion resistance to chloride contaminated media, such as seawater, neutral salts, and brines;
> Tests in geothermal brines indicate Alloy 625 is highly resistant to hot geothermal fluids comparable to Titanium Grade 2;
> Tests in simulated flue gas desulfurization environments show Alloy 625 highly resistant to the environment in comparison to alloys such as Alloy 316 AND Alloy 276.
