Characteristics Nickel 201 | 2.4068

A commercially pure Nickel (typically 99.6% Nickel), Nickel 201 is essentially the same as Nickel 200, but with a lower carbon content to prevent embrittlement by inter granular carbon at temperatures over 315°C (600°F). Lower carbon content also reduces hardness, which makes it ideally suited for spinning and cold forming. It is also preferred to Nickel 200 for applications involving exposure to temperatures above 315°C (600°F). These properties, and its chemical composition, make Nickel alloy 201 fabricatable and highly resistant to corrosive environments. Nickel 201 is useful in any environment above 600 ºF. It is highly resistant to corrosion by neutral and alkaline salt solutions, fluorine and chlorine. Nickel alloy 201 also has low corrosion rates in neutral and distilled water.

Nickel 201 can be hot formed to almost any shape. The temperature range 1200°F to 2250°F is recommended and should be carefully abided as the proper temperature is the most important factor in achieving hot malleability. Full information of the forming process should be sought and understood before proceeding. Nickel 201 can be cold formed by all conventional methods, but because nickel alloys have greater stiffness than stainless steels more power is required to perform the operations. JN Alloy have 30 years of experience supplying Ni 201 steel forgings and many other product forms to your custom measurements and shapes. Our forging process includes open die forgings, ring rolling and more. See below for a list of the common forged shapes and product forms we offer.

Chemical Composition of Nickel 201

Nickel 201, also known as UNS N02201, is a high-purity nickel alloy with a specific chemical makeup that enhances its performance in various industrial uses. Nickel 201 is composed of at least 99.0% nickel, with trace amounts of carbon (0.02% max), iron (0.40% max), manganese (0.35% max), silicon (0.35% max), copper (0.25% max), and sulfur (0.01% max). These elements are carefully balanced to enhance the alloy’s corrosion resistance, mechanical properties, and high-temperature performance. The low carbon content in Nickel 201 prevents brittleness at high temperatures, making it ideal for heat-resistant applications.

Nickel 201 meets industry standards such as ASTM B160/B162 for nickel rod, bar, wire, tube, plate, sheet, and strip, and ASME SB-160/SB-162 for boiler and pressure vessel applications. The high nickel content of Nickel 201 provides excellent corrosion resistance, while elements like manganese and silicon enhance its strength and formability. Its low carbon level is particularly beneficial for high-temperature uses, preventing brittleness and ensuring durability.
