PM Industries manufactures, supplies, and stocks Incoloy 925 Round Bar (UNS N09925). It's a nickel-iron-chromium alloy with molybdenum, copper, titanium, and aluminum additions. The titanium and aluminum allow the alloy to be age hardened, which pushes mechanical strength significantly above what solid-solution nickel alloys like 825 can achieve. That combination of high strength and good corrosion resistance is what makes 925 the preferred specification for downhole oilfield components where both properties are simultaneously required.

Incoloy 925 is closely related to 825 in corrosion resistance but considerably stronger in the aged condition. Where 825 is the right choice for corrosion-resistant process equipment that doesn't need exceptional strength, 925 is specified when load-bearing capability and corrosion resistance must both be met at the same time. That trade-off is especially relevant in oil and gas, where downhole pressures and mechanical loads are high and the environment is simultaneously corrosive.

Sour gas service is the primary application driver for 925. In environments containing hydrogen sulfide, carbon dioxide, chlorides, and elevated temperatures and pressures, the combination of sulfide stress cracking and chloride stress corrosion cracking eliminates most lower-alloy options. Incoloy 925 meets NACE MR0175/ISO 15156 requirements for sour service, which is the baseline qualification for downhole and wellhead components in oil and gas production systems.

Age hardening provides strength levels that solid-solution nickel alloys can't match without alloying additions that would compromise corrosion performance. After solution annealing and aging, 925 achieves tensile strengths typically in the range of 1000–1100 MPa with good toughness retained, making it suitable for shafts, fasteners, and connectors that carry significant mechanical load in service.

Fabrication should be done in the solution-annealed condition before final aging. Machining, forming, and welding are all more manageable before the age-hardening treatment. Final aging is performed after fabrication to develop full mechanical properties in the finished component.

Bar is available in solution-annealed and aged conditions across a range of diameters and surface finishes with full material certification to ASTM B805 and applicable specifications including NACE MR0175. Contact PM Industries for stock availability, dimensions, and pricing.
