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 characterized by resistance to oxidation and carburization, 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 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 suitable for bulk supply as well as in critical industry demands.
Stellar Alloys, as a leading Inconel 800 Pipe manufacturer and supplier in India has thrived in precision engineering of high performance piping solutions to comply with and suit the most challenging industrial conditions. To support the high-quality standards of the international standards and meet the requirements of all the rigorous mechanical and chemical requirements of ASTM B407, B163, and B514, our manufacturing plant employs modern production methods to ensure that each Alloy 800 (UNS N08800) pipe satisfies the requirements. We are offering key elements in the heat exchangers, petrochemicals processing, and power generation industries by producing materials that are highly resistant to high-temperature oxidation and carburization, and are also structurally stable. We are specialists in the whole production cycle meaning that even when our products are subjected to extreme thermal cycles and high pressure configurations they will not lose their integrity.
We have a complete stock of both seamless and welded Inconel 800 pipes which we use to meet a variety of engineering projects. We produce our smooth-flowing pipes by subjecting them to the process of hot-finishing and cold-drawing so as to produce uniformity in their grain structure so that they would be best suited in high-pressure systems where reliability is absolutely essential. When larger diameters are needed, our welded pipes are fabricated by automated ERW and EFW methods, a more economical, and would be more durable, the pipes would be made in compliance with the ASME and ASTM compliance procedure. This twofold ability enables us to serve our purposes as a one- stop-shop where engineers need to acquire particular types of pipes in standard and custom designs of industrial designs.
Quality assurance is incorporated in all the processes of our operations where all the pipes are tested against their chemical accuracy and mechanical functionality. Our materials are subjected to a set of tests, such as hydrostatic, ultrasonic and eddy current tests, to determine their serviceability. In the process of selecting all essential material traceability and complete transparency, a detailed Manufacturer Test Certificate (MTC) is attached to each shipment in accordance with EN 10204 3.1. This document proves the fact that the nickel, chromium, and iron content together with tensile and yield strength are just right in accordance with the high-intent specifications demanded by world-wide industrial contractors.
Stellar Alloys has also been known to have strong project and export abilities and has a wide global customer base with easy logistics and specialized customer care. We are well experienced in handling bulk orders of large scale on domestic refineries and international infrastructure projects. Our logistics team uses special seaworthy packaging such as heavy-duty wooden crates and protective end-caps to keep our products in their pristine condition without any contamination of the surface and physical damages during the transit process. You need either standard lengths or cut-to-size solutions, we proudly guarantee to deliver at the required time and complete reports will help you rely on us to provide piping made of Inconel 800 in the global market.

The sheets are best suited in the production of high pressure vessels, sea-water parts, and aerospace exhaust systems where it is crucial to be able to endure when extreme conditions are taken into consideration. We have 625 alloy inventory in different thickness and finishes to match your particular fabrication requirements.







While nickel-iron-chromium alloys are essential for high-temperature stability, many industrial systems also utilize stainless steel pipe and tube for reliable corrosion resistance in less extreme conditions. Comparing these material grades ensures you select the most efficient and durable piping solution tailored to your specific pressure and thermal requirements.

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 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.
