Inconel 690: High-Temperature Nickel-Chromium Alloy With Excellent
Oxidation And Corrosion Resistance
Inconel 690 Alloy
Inconel 690 is a high-performance nickel-chromium alloy
specifically designed for superior resistance to oxidation and
carburization in extreme environments. It is renowned for its
strength and stability at elevated temperatures, making it suitable
for demanding applications.
Key Features:
- Exceptional Corrosion Resistance: Provides excellent protection against oxidation, carburization,
and sulfidation, particularly in high-temperature settings.
- High Temperature Stability: Maintains mechanical strength and integrity at temperatures up to
1200°C (2192°F), making it ideal for use in high-heat applications.
- Mechanical Properties: Offers high tensile strength (up to 690 MPa or 100 ksi) and good
yield strength (310 MPa or 45 ksi), with a minimum elongation of
30%, ensuring durability and flexibility.
- Thermal Conductivity: Features a thermal conductivity of about 11.0 W/m·K, which aids in
effective heat distribution and resistance to thermal cycling.
- Fabrication Versatility: Available in various forms including sheets, plates, bars, pipes,
and welding wire, suitable for a wide range of industrial
applications.
Applications:
- Nuclear Reactors: Used in components that operate under high temperatures and
aggressive conditions.
- Chemical Processing: Ideal for equipment and components exposed to harsh chemicals and
high temperatures.
- High-Temperature Furnaces: Suitable for parts in furnace environments where resistance to
thermal degradation is critical.
Standard Specifications:
- ASTM B166
- ASTM B167
- ASTM B168
Inconel 690 combines high strength, excellent oxidation resistance,
