Oilfield Operators Demand:

• High strength-to-weight ratio, critical for deep well applications.

• Reliable resistance to SSC for operations in sour fields.

• Consistent material properties across all production batches.

• Cost-effective alternative to more expensive alloys.

Fastener Manufacturers Require:

• Precision machinability for accurate threading.

• Consistency in heat treatment to achieve uniform material properties.

• Complete traceability for quality assurance.

• Compliance with NACE MR0175/ISO 15156 for sour service applications.

Oil & Gas Downhole Tools

• Drilling Components: Incoloy 925 is widely used in the manufacturing of drill collars and heavy weight drill pipes. These components are subjected to extreme mechanical stress and must be able to withstand high temperatures and corrosive environments, making Incoloy 925 a perfect material choice due to its high yield strength and corrosion resistance.

• Measurement While Drilling (MWD) Housings: Incoloy 925’s corrosion resistance ensures it can reliably withstand the harsh conditions encountered in MWD applications, where tools are exposed to continuous pressure and high temperatures.

• Logging While Drilling (LWD) Tool Bodies: Similar to MWD housings, LWD tool bodies are exposed to intense stresses and corrosive substances. Incoloy 925 is used for LWD tool bodies due to its ability to perform in H₂S and CO₂ environments, which are common in deep drilling applications.

Completion Equipment

• Production Packers and Bridge Plugs: Used in well completion operations, these components help isolate areas of the wellbore and are exposed to high mechanical loads and corrosive fluids. The outstanding resistance to sulfide stress cracking (SSC) of Incoloy 925 ensures these tools function reliably in sour environments.

• Subsurface Safety Valve Components: Incoloy 925 is also used for critical parts in subsurface safety valves, which must operate reliably under extreme pressure and corrosive conditions. Its strength and corrosion resistance make it a trusted material for this vital equipment.

• Sand Control Tooling: Sand control is a critical aspect of well completion, and Incoloy 925’s fatigue and corrosion resistance ensure the sand control tools can withstand erosive forces and the pressures of downhole environments.

Intervention Tools

• Fishing Tools and Milling Equipment: In oil and gas operations, fishing tools (used to recover equipment lost in the wellbore) and milling equipment (used to cut or remove metal parts) require materials that can endure high impact and wear. Incoloy 925’s excellent fatigue resistance and high toughness make it ideal for these demanding applications.

• Workover String Components: During well repair and maintenance operations, Incoloy 925’s ability to handle cyclic stresses and high temperatures makes it ideal for workover strings—critical components used in well intervention.

• Wireline Tooling: Used for logging and downhole data acquisition, wireline tools face constant wear from high-temperature and high-pressure environments. Incoloy 925 ensures reliable wireline tooling that can operate in these tough conditions.

High-Strength Fasteners

• Sour Service Bolts and Studs: Incoloy 925’s resistance to sulfide stress cracking (SSC) and chloride corrosion makes it ideal for sour service fasteners. It is widely used for bolts, studs, and other fasteners in critical equipment exposed to H₂S, CO₂, and other corrosive substances.

• Wellhead and Christmas Tree Components: These components are essential for controlling and monitoring production at the wellhead. Incoloy 925’s high strength and resistance to corrosion ensure long-term reliability in wellhead equipment.

• Subsea Connector Systems: In subsea oil and gas operations, equipment must withstand extreme pressures and corrosive conditions. Incoloy 925 is ideal for subsea connectors due to its excellent corrosion resistance, making it an essential material for offshore fasteners.

• Platform Structural Fasteners: Offshore platforms require high-strength fasteners to maintain the structural integrity of equipment exposed to harsh environmental conditions. Incoloy 925 is used for critical platform fasteners, offering both strength and corrosion resistance.
