General scope
Alloy 925 is a nickel based alloy containing Iron and Chromium as major additions, and also additions of Molybdenum, Copper, Titanium and Aluminium. A combination of high strength and corrosion resistance make it suitable in applications such as valves, hangers, packers, and tubulars, in sour gas environments. It can also be used for fasteners, and for pump shafts in marine environments.
The combination of Nickel and Chromium renders protection in both oxidizing and reducing atmospheres. The high Nickel content also gives resistance to chloride ion stress-corrosion cracking. Pitting and crevice corrosion resistance is also excellent. The alloy is produced by a vacuum remelt process, but can be supplied using an air melt single consumable electrode (VAR or ESR) practice if the material specification allows.
