Why Incoloy 800H for Weld Neck Flanges
Incoloy 800H (UNS N08810) is widely used in high-temperature and high-stress applications due to its stable microstructure and excellent mechanical strength.
Key material advantages include:
- Outstanding resistance to oxidation and carburization
- Good creep and rupture strength at elevated temperatures
- Excellent performance in petrochemical and energy applications
- Proven suitability for NACE-related service conditions
When combined with a weld neck design, these properties ensure superior load distribution, reduced stress concentration, and long-term reliability in critical piping systems.
Typical Applications
Incoloy 800H WN flanges are commonly used in:
- Oil and gas processing facilities
- Petrochemical and refinery piping systems
- High-temperature process units
- Power generation and heat transfer equipment
