Why Choose Inconel

• Extreme High-Temperature Strength 

  Retains 900+ MPa UTS at 650°C — temperatures at which stainless steel and titanium have significantly reduced strength. For gas turbine components, exhaust manifolds, and rocket nozzles, superalloys are irreplaceable.

• Exceptional Corrosion Resistance

  Resistant to chloride stress corrosion cracking, pitting, and crevice corrosion in seawater — outperforming even duplex stainless steel in the most aggressive marine environments. Used for subsea wellhead equipment and offshore chemical injection systems.

• Oxidation Resistance

  Superalloys form a stable protective oxide at high temperatures — resisting oxidation and scaling at temperatures where other metals would burn. Essential for components in direct contact with combustion gases.

• Fatigue and Creep Resistance

  Excellent fatigue and creep resistance at elevated temperature makes superalloys the standard for turbine disks and rotating components where sustained high-temperature loading would cause deformation in other alloys.

Common Inconel Grades

• Inconel 718

  Precipitation-hardenable nickel-chromium alloy — combines high strength (up to 1,380 MPa UTS) with good corrosion resistance and excellent fatigue properties. The most widely used nickel superalloy. Standard for aerospace turbine disks, shafts, and structural components.

• Our Machining Capability

  Inconel and nickel superalloys are among the most difficult materials to machine — they work-harden severely during cutting, have low thermal conductivity (heat concentrates at the tool), and are highly abrasive to standard carbide tooling.We machine Inconel on dedicated setups using CBN tooling for hardened material, premium carbide with appropriate coatings for softer conditions, conservative feed and speed parameters, and frequent tool changes to prevent work-hardening buildup. Tolerances held to ±0.005 mm. All superalloy batches ship with full material traceability and CMM dimensional reports.

• Limitations & Cost Considerations

  Inconel and superalloys are the most expensive material category we machine — both in raw material cost and machining time. Cycle times for complex parts can be 5–10× longer than equivalent titanium parts and 20–30× longer than aluminum. They should only be specified when the temperature and corrosion environment genuinely requires them. For many aerospace structural applications, titanium is lighter and less expensive to machine. For many corrosive chemical applications, duplex stainless or titanium may be sufficient.
