Material Composition & Properties

Mechanical Properties:

• • • Tensile Strength: ≥760 MPa
    • Yield Strength (0.2% offset): ≥345 MPa
    • Elongation: ≥30%
    • Hardness: ≤30 HRC
  • Corrosion Resistance:
    • Withstands sulfuric acid, phosphoric acid, and seawater environments.
    • Resists oxidation up to 1000°C (1832°F).
  • Thermal Stability:
    • Maintains strength and ductility in cryogenic to high-temperature ranges (-196°C to 1000°C).

Key Characteristics:

1. Exceptional Corrosion Resistance: Offers superior resistance to a wide range of severe environments, including:

   • Acidic Media: Phosphoric, sulfuric, and hydrochloric acids (in the absence of air and oxidizing conditions).

   • Alkaline Media: Various hydroxides.

   • Localized Corrosion: Excellent resistance to pitting, crevice corrosion, and intergranular attack.

   • Marine Environments: Highly resistant to seawater and saltwater spray.

2. Excellent High-Temperature Strength: Retains high mechanical strength from cryogenic temperatures up to approximately 1000°C, primarily due to solid-solution strengthening from niobium and molybdenum.

3. Outstanding Fatigue and Creep Resistance: Resists slow plastic deformation (creep) and fatigue failure under long-term exposure to high temperatures and stresses.

4. Good Weldability and Fabrication Properties: Compared to other high-performance alloys, Inconel 625 offers good weldability without post-weld cracking susceptibility.

Applications

• • Aerospace: Jet engine components (combustor liners, turbine seals), rocket propulsion systems.
  • Oil & Gas: Subsea equipment, downhole tools, and pipelines in corrosive offshore environments.
  • Chemical Processing: Reactors, heat exchangers, and valves handling acidic or high-temperature media.
  • Power Generation: Nuclear reactor components, boiler tubes, and gas turbine parts.
  • Marine: Propeller shafts, seawater piping, and offshore platform hardware.
