- Form: Forged bar (round, square, or hexagonal cross-sections available)
- Manufacturing Process: Hot forging followed by solution annealing and aging treatments to optimize mechanical properties
Compliance Standards
- API 6A: Complies with the latest edition of API Specification 6A for wellhead and Christmas tree equipment
- Material Certification: Meets ASTM B637 specifications for Inconel 718 forgings
- Quality Assurance: Traceable material certification, ultrasonic testing (UT), magnetic particle inspection (MPI), and chemical composition verification
Mechanical Properties
- Tensile Strength: Minimum 130 ksi (900 MPa)
- Yield Strength (0.2% offset): Minimum 100 ksi (690 MPa)
- Elongation: Minimum 12% in 2 inches (50 mm)
- Hardness: Typically 30-40 HRC after heat treatment
- Operating Temperature Range: -423°F to 1,300°F (-253°C to 704°C)
Corrosion Resistance
Inconel 718 provides excellent resistance to:
- Sour environments containing hydrogen sulfide (H₂S)

- Lengths: Up to 20 feet (6 meters) or as per customer requirements
- Custom sizes and configurations available upon request
- Machining services offered to meet specific dimensional tolerances
Quality Control
Each forging bar undergoes rigorous quality control measures, including:
- Chemical composition analysis (spectroscopic testing)
- Mechanical property testing (tensile, impact, hardness)
- Non-destructive testing (UT, MPI)
- Dimensional verification
- Microstructural examination
This API 6A CRA Inconel 718 Forging Bar represents the industry standard for high-performance components in demanding oilfield applications, combining superior strength, toughness, and corrosion resistance to ensure reliable operation in extreme environments.
