Incoloy 925 Suppliers - Nickel Alloy 925 , UNS N09925Alloy 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.
Corrosion Resistance of Nickel Alloy 925
INCOLOY alloy 925 has a high level of corrosion resistance. In both reducing and oxidizing environments, the alloy resists general corrosion, pitting, crevice corrosion, intergranular corrosion and stress-corrosion cracking. Some environments in which INCOLOY alloy 925 is particularly useful are “sour” (H2S containing) crude oil and natural gas, sulfuric acid, phosphoric acid, and seawater. The performance of INCOLOY alloy 925 under conditions representing sour gas wells.

NACE MR0175 limits the hardness to 38 HRC max.
Many different industries rely on Alloy 925 for a number of uses including:
- Valves, hangers, packers, and tubulars for sour gas production
- Marine fasteners and pump shafts
MachinabilityIncoloy Alloy 925 can be machined using conventional machining methods which are used for iron based alloys.
Tooling and heavy duty machining equipments are used to reduce work-hardening of this alloy.
Machining operations can be performed by using commercial coolants.
High speed operations such as grinding, turning, or milling, are usually performed using water-based coolants.
