Inconel 800 pipe is a nickel-iron-chromium compound that was developed to offer high structural stability and strength when used in a high-temperature setting. This material is also characterised by resistance to oxidation and carburisation, as well as thermal fatigue, and is a reliable material that operates well in the harsh environment of industry. It is also known as Incoloy 800 pipe & tube or alloy 800 pipe (UNS N08800) and is a popular material in industrial piping systems, heat exchangers, furnaces, and petrochemical processing units.
Alloy 800 seamless pipe is used when there is a need to use high pressure and high temperature. These pipes are provided by trusted manufacturers of Inconel 800 pipes of different sizes and specifications, depending on the needs of the project. Inconel 800 pipeline pricing is also based on the size, specifications, and volume ordered, hence it is suitable for bulk supply as well as critical industry demands.

Seamless pipes are produced either through extrusion or rotary piercing. The welded seam is nonexistent and they are therefore better suited in high pressure applications where uniformity of strength in the pipe body is imperative. They are usually utilized in high-performance heat transfer machinery.
Welded pipes are made out of rolled and welded strips or plates. They are of lower cost in general than seamless, and come in larger diameter. These can be applied in environmental conditions of lower pressure and in structures.

The use of Inconel 800 is in the industries that need corrosiveness and high temperature:
While they share the same basic composition, the differences lie in carbon, aluminum, and titanium levels to handle specific creep-rupture requirements.
Stellar Alloys Steel Pipes and Tubes is a trusted name among inconel 800 pipe manufacturers due to our commitment to quality and service.

UNS N08800 is the Unified Numbering System designation for Inconel/Incoloy 800, defining its specific chemical composition of Nickel, Iron, and Chromium.
The primary standards are ASTM B407 for seamless pipe and tube, and ASTM B514 for welded pipe.
Seamless pipe is extruded and has no seam, offering higher pressure ratings. Welded pipe is made from rolled plate and is generally more economical for larger diameters.
Inconel 800 is generally used for service temperatures up to 1100°F (593°C). For higher temperatures requiring creep resistance, grades 800H or 800HT are recommended.
It consists of 30-35% Nickel, 19-23% Chromium, and the balanced Iron, providing excellent resistance to oxidation and carburization.
