Seamless Incoloy 825 tube
Seamless Incoloy 825 tube is a high-performance nickel-iron-chromium alloy (UNS N08825) tube. It is made by advanced metallurgical technology. It is formed by precise hot extrusion or cold rolling. This makes the tube have uniform structure and no internal defects. The chemical composition of Seamless Incoloy 825 tube is carefully designed. Nickel (38-46%) is the base. It provides excellent corrosion resistance and high-temperature stability. Chromium (19.5-23.5%) improves oxidation resistance. Molybdenum (2.5-3.5%) and copper (1.5-3.0%) are added. They greatly increase resistance to reducing acids and localized corrosion. Titanium (0.6-1.2%) is also added. It improves welding performance by stabilization treatment. The structure of Seamless Incoloy 825 tube makes it have great reliability and long life in high pressure, high temperature and strong corrosive media.
Seamless Incoloy 825 tube has advantages like corrosion resistance, high temperature resistance, high strength and easy processing. It is suitable for long-term high reliability needs in chemical, energy, and marine fields. Its seamless structure further improves safety and service life. It is an essential key component for high-end industrial equipment.
Features of Seamless Incoloy 825 tube
Superior Corrosion Resistance
Seamless Incoloy 825 tube stays stable in strong acids like sulfuric acid, phosphoric acid, and nitric acid. It works well in conditions with chloride ions, such as seawater and salt spray. Its resistance to chloride stress corrosion cracking (SCC) is much better than 304/316 stainless steel.
Seamless Incoloy 825 tube can handle both reducing media (like dilute sulfuric acid and sulfurous acid) and oxidizing media (like nitric acid). It has a wide range of applications.
Excellent High-Temperature Performance
Seamless Incoloy 825 tube can work stably below 540°C for a long time. It has excellent oxidation and carburization resistance. It is suitable for high-temperature equipment like heat exchangers and boiler pipes.
Seamless Incoloy 825 tube has good low-temperature toughness. It keeps good mechanical properties even at extremely low temperatures of -196°C.
Outstanding Mechanical Strength and Workability
Tensile strength is ≥586 MPa, and yield strength is ≥241 MPa. Seamless Incoloy 825 tube has both high strength and good ductility. It is easy to form by cold bending and flaring.
Seamless Incoloy 825 tube has good welding performance. It can be welded by TIG, MIG, and stick welding. No complicated heat treatment is needed after welding.
Advantages of Seamless Structure
Compared with welded pipes, Seamless Incoloy 825 tube has no weak points from welds. It has higher overall uniformity. It is suitable for high-pressure fluid transport, precision instruments, and high-stress structural components.
The inner surface of Seamless Incoloy 825 tube is smooth. It has low fluid resistance. It reduces the risk of scaling and corrosion, and it extends service life.
