Incoloy 800, also known as Alloy 800 (UNS N08800), is a nickel-iron-chromium superalloy renowned for its exceptional resistance to oxidation, carburization, and nitridation at elevated temperatures. Developed for applications where structural stability and corrosion resistance are paramount, this alloy maintains its integrity in harsh conditions up to 1100°C.
Unlike conventional stainless steels, Incoloy 800 resists embrittlement from prolonged exposure to intermediate temperatures 1200°F–1600°F, making it ideal for long-term service in aggressive atmospheres.
Features and Benefits of Our Incoloy 800 Flanges
Our Incoloy 800 flanges stand out due to their superior material characteristics and manufacturing precision. The alloy's balanced composition offers excellent creep-rupture strength, particularly in variants like 800H and 800HT, which incorporate controlled levels of carbon, aluminum, and titanium for enhanced high-temperature performance.
Benefits include:
High-Temperature Stability: Retains mechanical properties in oxidizing and reducing environments, preventing scaling and structural failure.
Corrosion Resistance: Excels in acidic settings, resisting attacks from sulfur, chloride, and other corrosives, as noted in industry benchmarks.
Weldability and Formability: Easily welded without post-weld annealing, facilitating seamless integration into complex assemblies.
Versatility: Available in custom sizes and configurations to meet specific project needs, from small-diameter fittings to large industrial components.
By choosing Jinie, clients benefit from products that not only comply with but exceed expectations, backed by our rigorous quality controls.
Types of Incoloy 800 Flanges We Manufacture
We offer a comprehensive range of Incoloy 800 flanges to suit diverse applications. Each type is precision-machined for optimal fit and performance:
Weld Neck Flanges (WNRF): Ideal for high-pressure systems, providing a smooth transition and superior stress distribution.
Slip-On Flanges (SORF): Cost-effective for low-pressure applications, easy to align and weld.
Blind Flanges (BLRF): Used to seal pipe ends, offering robust closure in testing or isolation scenarios.
Socket Weld Flanges (SWRF): Suitable for small-diameter, high-pressure lines, ensuring leak-proof joints.
Lap Joint Flanges: Flexible for systems requiring frequent disassembly, compatible with stub-end fittings.
Threaded Flanges: Convenient for non-welded installations in low-pressure environments.
Orifice Flanges: Designed for flow measurement, with precise tapping points.
Spectacle Blind and Ring Joint Flanges: Specialized for maintenance and high-integrity sealing in critical operations.
Additionally, we produce reducing flanges, long weld neck flanges, and forged flanges, all available in sizes from 1/2" NB to 60" NB. Our inventory includes ANSI B16.5, B16.47 Series A & B, and custom designs to match client specifications.
