ASTM B407 is a standard specification for seamless nickel-iron-chromium alloy pipes. It is commonly used in high-temperature applications such as steam production, chemical processing, and nuclear power generation. UNS N08800 exhibits good resistance to oxidation, carburization, and corrosion in various environments.

The ASTM B407 UNS N08800 seamless pipes are manufactured using a variety of processes such as hot-finished or cold-drawn. In the hot-finished process, the temperature of the material is raised above the recrystallization temperature before being worked. The cold-drawn process involves reducing the diameter of the material by drawing it through a die at room temperature.
