Introduction
Incoloy 925 Bar (also Incoloy 925 Round Bar, Alloy 925 Bar, Nickel Alloy 925 Bar, UNS N09925 Bar, Incoloy 925 Forged Bar, Oilfield Alloy Bar, High Strength Nickel Alloy Bar, Corrosion Resistant Alloy Bar) is a precipitation‑hardenable nickel‑iron‑chromium alloy specifically designed for sour gas oilfield service. It conforms to ASTM B805 and meets NACE MR0175 / ISO 15156 requirements for H₂S‑containing environments. This high strength age hardening alloy offers an exceptional combination of sulfide stress cracking resistance, high mechanical strength, excellent sour gas resistance, chloride stress corrosion resistance, and seawater corrosion resistance, making it the preferred material for downhole tools, packers, tubing hangers, and wellhead equipment in oil and gas production.
Key properties of Incoloy 925:
Excellent sour gas resistance – certified for NACE MR0175/ISO 15156 up to Region 3 (partial pressure H₂S > 10 mbar)
Sulfide stress cracking resistance – immune to SSC in sour environments up to 260°C (500°F)
High strength age hardening alloy – yield strength up to 900‑1100 MPa (130‑160 ksi) after age hardening, enabling lightweight, high‑pressure components
H₂S resistant nickel alloy – designed for downhole sour gas service, outperforming super duplex and martensitic stainless steels
Chloride stress corrosion resistance – excellent resistance to Cl‑SCC in high‑temperature brine
Seawater corrosion resistant alloy – suitable for offshore applications, completion fluids, and marine exposure
High fatigue strength material – good fatigue life for cyclic pressure and vibration loading in downhole tools
Precipitation hardenable – strengthened by γ′ and γ″ phases, with good ductility and toughness
Note: Incoloy 925 is the higher strength version of Alloy 825, optimized for oilfield sour service with age‑hardening capability. It is not recommended for primary acid service (use Alloy 825).
This oilfield alloy bar is available in hot rolled, cold drawn, forged, solution annealed, and age hardened conditions. We offer custom sizes, cut to length, precision machined, and bright finished bars, with diameters from small to heavy diameter Incoloy 925 bar. Our product range includes Incoloy 925 round bar, forged bar, rod, cold drawn bar, and age hardened bar, available in solution annealed or age hardened (precipitation hardened) conditions.

Applications
1. Downhole Tools & Completion Systems
Incoloy 925 bar for downhole tools – perforating gun components, drilling stabilizers, jar parts, and wireline tools in high‑pressure, sour gas wells. High strength nickel alloy bar with H₂S resistance ensures safe operation up to 260°C and > 10 mbar H₂S partial pressure.
Incoloy 925 bar for packers – packer mandrels, slips, and seal housings in completion systems. High fatigue strength material withstands setting loads, pressure cycles, and thermal expansion without galling.
Incoloy 925 bar for completion systems – landing nipples, sliding sleeves, and gas lift mandrels. Sulfide stress cracking resistance prevents brittle failure in wells with up to 30% H₂S.
2. Wellhead & Subsea Equipment
Incoloy 925 bar for tubing hangers – tubing hanger stems, load rings, and lockdown components in tree and wellhead systems. High pressure oilfield alloy with NACE MR0175 compliance is required for API 6A equipment in sour service.
Incoloy 925 bar for wellhead equipment – bonnet studs, valve stems, and choke components in Christmas trees. Seawater corrosion resistant alloy performs in offshore splash zone and subsea.
Incoloy 925 bar for subsea equipment – connector bolts, actuator rods, and fastener blanks for subsea trees and manifolds. Age hardening capability provides 110 ksi minimum yield for high‑pressure designs.
3.Offshore Drilling & OCTG Applications
Incoloy 925 bar for offshore drilling – drill string components, logging tool housings, and MWD/LWD tool bodies. Corrosion resistant downhole material resists both seawater and sour reservoir fluids.
Incoloy 925 bar for OCTG applications – accessory parts for casing and tubing (e.g., centralizers, torque rings, wear sleeve adapters). High strength allows use in deepwater, high‑collapse wells.
Oilfield alloy bar – also used in safety valve components, side pocket mandrels, and chemical injection sleeves.
4. Sour Gas Service & High Pressure Equipment
Incoloy 925 bar for sour gas service – control line components, pressure gauge adapters, and flowmeter bodies in H₂S/CO₂ service. NACE compliant alloy eliminates risk of sulfide stress cracking.
Incoloy 925 bar for high pressure oilfield equipment – blowout preventer (BOP) studs, connector flanges, and pressure test tools. Pre‑aged material provides dimensional stability after final machining.
