All you Need to Know About Alloy 800 Tube

Our modern world thrives on innovation and technology. Everything we have is a result of science and engineering research, from the cars we drive to the planes we fly in and the smartphones we use. As a result, using advanced materials and techniques has become an essential part of our daily lives. One such material is Alloy 800, which is a Nickel-Iron-Chromium alloy. Alloy 800 tube is a popular choice in various industrial sectors, and in this comprehensive guide, we will dive deep into everything you need to know about this material.

What is Alloy 800 Tube?

Alloy 800 Tube is a nickel-iron-chromium alloy containing a minimum of 19% chromium and 9% nickel. This high-temperature, corrosion-resistant material provides superior strength and oxidation characteristics, making it an ideal choice for heat exchanger tubing, petrochemical applications, and more. Its high-temperature properties make it especially useful in nuclear power plants.

Properties of Alloy 800 Tube

Alloy 800 has several unique properties, making it an ideal choice for various industrial applications. One of its most significant advantages is its excellent resistance to high-temperature oxidation, which makes it ideal for use in furnaces and other high-temperature environments. It also has excellent resistance to nitriding and carburization, making it ideal for chemical processing plants. The alloy also has high creep and rupture strength, which means it can withstand hot environments for extended periods.

Manufacturing Process of Alloy 800 tubes

Alloy 800 tubes are manufactured using various processes, including seamless extrusion and cold drawing. Cold drawing involves using a mandrel to guide the metal tube through a die, resulting in a smooth, uniform wall thickness. Seamless extrusion, on the other hand, involves using a starting material forced through a die to produce a long, continuous tube with the desired diameter and wall thickness.

Applications of Alloy 800 Tube

As mentioned earlier, Alloy 800 tube extensively uses in various industrial sectors. Due to its excellent properties, it is used in heat exchangers, steam generators, petrochemical refineries, and chemical processing plants. It is also commonly used in furnace applications, where it can withstand high temperatures without corroding. Additionally, the alloy is used in the aerospace industry, where it is used in the production of gas turbine engines.

Types of Alloy 800 Tube

Several Alloy 800 tubes are available, each with unique properties and advantages. These include:

Alloy 800 Seamless Tubes: As the name suggests, it is a tube made from a single piece of Alloy 800. Seamless tubes have better corrosion resistance and are ideal for applications that require high precision.

Alloy 800 Welded Tubes: It is made from several pieces of Alloy 800 welded together. Welded tubes are more cost-effective than seamless tubes and are ideal for applications that do not require high precision.

Advantages of Alloy 800 tubes

One of the significant benefits of Alloy 800 tubes is their ability to resist oxidation and corrosion in high-temperature environments. They also have excellent mechanical strength and toughness, making them ideal for use in extreme conditions. Additionally, their good weldability and formability make them easy to work with, allowing easy customization to suit specific application needs.


Alloy 800 tube is a critical material essential in various industrial applications. Its unique properties make it an excellent choice for high-temperature and corrosion-resistance applications. By understanding the properties and types of Alloy 800 tubes, you can choose the right material for your specific application and derive maximum benefit from it.
