Nickel 201, also known as Ni-201 alloy or N02201 alloy, is a low carbon version of Nickel 200. It exhibits excellent corrosion resistance and thermal stability, making it suitable for various applications in chemical processing, petrochemical, marine, and other industries. In this article, we will discuss the chemical composition, mechanical properties, heat treatment condition, size range, primary applications, and TJC Steel supply case of Nickel 201 seamless and welded pipes.

Chemical Composition

Nickel 201 contains a minimum of 99.0% nickel, with the addition of small amounts of iron, copper, manganese, carbon, and silicon. The low carbon content of Ni-201 alloy reduces its vulnerability to embrittlement caused by the formation of intermetallic compounds between nickel and carbon during high-temperature processing.

Mechanical Properties

The mechanical properties of Ni-201 alloy depend on the heat treatment and annealing conditions. In the annealed state, it has a tensile strength of 55 ksi (380 MPa), yield strength of 15 ksi (105 MPa), and elongation of 40%. Ni-201 alloy can be cold worked to increase its strength and hardness, with a maximum working temperature of 600°F (315°C). However, it is prone to stress corrosion cracking in certain environments and should be used with caution.

Heat Treatment Condition

Ni-201 alloy can be annealed in a temperature range of 900-1400°F (480-760°C) to obtain the desired mechanical properties. It can also be solution treated at 1300-1750°F (710-955°C) followed by water quenching for hardening. Stress relieving annealing can be performed at 600-900°F (315-480°C).
