Incoloy 800H Pipe is a mix of nickel, iron, and chromium, made for when you need something strong that won't corrode, even if it's used all the time above 600°C. It's like a better version of the 800-series, with the right amount of carbon, grain size, and heating to make it work well. This pipe is good for things like thermal processing, petrochemical reactors, and furnaces that are always hot.
It's made with a balance of nickel, chromium, and iron, plus some aluminum, titanium, and carbon to help it resist wear and tear. Usually, these pipes are made by hot extrusion or cold drawing, depending on how precise they need to be. Jiangsu CunRui Metal Products Co., Ltd sells Incoloy 800H Pipe that meets ASTM B407, ASME SB407, and UNS N08810 standards. Every batch is checked to make sure it's made of the right stuff and can handle the pressure, so you know you're getting quality pipes in the size you need. Because it's so stable, it stays strong even after being heated up and cooled down a lot, which is super important for factory work.

Features & Advantages
Highly resistant to oxidation and carburization
Incoloy 800H Pipe creates a stable oxide film at high temperatures, providing long-term protection in furnaces, reformers, and heaters. This lowers metal loss and increases the service life of components exposed to direct flame or hot gasses.
High strength at high temperatures
The alloy's designed carbon and grain structure allow the pipe to endure heavy mechanical loads. It is typically used for pressure piping or support tubes with temperatures around or above 800°C.
Stable mechanical performance
Even after repeated heat cycling, Incoloy 800H maintains its dimensional stability. Components remain aligned and resist distortion, reducing maintenance downtime in continuous operation factories.
Our Strength

Having strong, lasting deals with melting mills and a solid machining process lets us maintain steady stock levels of common sizes and make sure everything performs the way it should.
- Experience with high-temperature alloys.
Our team works with nickel-based materials on a daily basis, so we can advise customers on their applicability, processing behavior, and long-term performance.
- Reliable inspection and documentation.
We provide visible, verifiable quality assurance, which includes PMI testing, pressure testing, and third-party inspection.
- Export-oriented packaging and delivery.
Years of export experience have enabled us to manage orders smoothly, regardless of shipment size or destination.
Applications
- Petrochemical and refinery facilities
Incoloy 800H Pipe is commonly used in steam reformers, ethylene cracking units, transfer lines, and pipe systems that contain carburizing or oxidizing gasses. Its temperature stability helps businesses decrease unplanned downtime and increase output consistency.
- Power generating and industrial heating
The alloy works well for superheater tubes, furnace manifolds, and high-temperature heat exchanger pipework. These applications necessitate materials that can withstand sagging and creep.
- Thermal processing and metallurgy
Incoloy 800H is used in heat-treating equipment, kilns, support rails, and radiant tubes to keep their shape and mechanical strength during cyclical heating.
- Marine and offshore engineering
Components exposed to hot exhaust streams benefit from its oxidation resistance and structural strength.
Customized Services
Special wall thickness and non-standard OD
We may create unique OD and thickness combinations for customers who use specific refinery or furnace equipment.
Small batch prototype production
Customers developing new equipment may request small quantities for testing before mass manufacturing.
Precision cutting and beveling
We provide heat-resistant cutting and correct end preparation for welding, which reduces on-site workload and installation time.
Surface Cleaning and Pickling
For tasks that require cleanliness, pipes can be delivered pickled, polished, or with controlled surface roughness.
