Incoloy 800 bars are specially designed for high-temperature and high-stress applications. Their properties make them ideal for use in environments where traditional materials would fail due to excessive heat, radiation, or corrosive exposure.

• Neutron Irradiation Stability: The low cobalt content (<0.10%) reduces long-lived isotope activation, such as Co-60, which is vital for nuclear applications.

• Creep-Fatigue Resistance: Capable of enduring 10⁵ cycles at 700°C with 150 MPa stress amplitude, making it ideal for power plant systems and heat treatment furnaces.

• Ultra-High Vacuum (UHV) Compatibility: Incoloy 800 bars exhibit an outgassing rate of less than 1×10⁻⁹ Torr·L/s/cm² after electropolishing, ensuring reliability in aerospace and vacuum applications.

• Corrosion Resistance: Withstands borated water (3,000 ppm boron) in pressurized water reactors (PWRs) without stress corrosion cracking, which is crucial for nuclear reactors.

• Dimensional Precision: Manufactured to tight tolerances (±0.05% of nominal diameter) for critical components, ensuring high performance and reliability in demanding environments.

1. Vacuum Induction Melting (VIM) + VAR: This process reduces impurities such as oxygen and nitrogen, ensuring radial homogeneity and material purity.

2. Isothermal Forging: Performed at 1050°C (1922°F) under 150 MPa pressure to eliminate porosity and enhance the material’s structural integrity.

3. Heat Treatment: Includes homogenization at 1150°C (2102°F) for 4 hours and stabilization annealing at 750°C (1382°F) for 16 hours to optimize precipitate distribution and enhance mechanical properties.

4. Quality Control: Neutron radiography is used for detecting sub-surface defects, ensuring integrity for nuclear applications. Residual stress is analyzed via X-ray diffraction (XRD), and helium leak testing ensures that components meet UHV requirements.

Incoloy 800 alloy bars owe their high performance to advanced nuclear-grade engineering:

• Low-Activation Design: Minimizing cobalt (Co) and other elements like tantalum (Ta) and niobium (Nb) reduces the residual radioactivity in neutron flux environments, making it ideal for nuclear reactors.

• Radiation-Induced Defect Mitigation: The high nickel content helps in the recombination of radiation-induced Frenkel pairs, preserving ductility and mechanical properties even after prolonged exposure to radiation.

• Boron Compatibility: The alloy's chromium-rich oxide layer prevents boron ingress, which is crucial for maintaining structural integrity in PWR coolant systems.

• Grain Boundary Pinning: Nano-scale titanium nitride (TiN) precipitates (5-20 nm) stabilize grain boundaries, making the alloy resistant to thermal and irradiation-induced creep.

Incoloy 800 alloy bars are integral in industries that demand materials with exceptional strength and stability under extreme conditions. Key applications include:

• Control Rod Drive Mechanism Shafts: Critical components in nuclear reactors where precision and durability are essential.

• Reactor Vessel Internals: Used for components subjected to high neutron flux and thermal cycling.
