UNS N02201 Nickel Alloy 201 Threaded Flanges are high-performance components known for their superior resistance to corrosive environments and excellent mechanical strength. Nickel Alloy 201 is a low-carbon version of Nickel 200, specifically designed to minimize the risk of graphitization in high-temperature environments. With a nickel content of approximately 99.6%, this alloy is highly resistant to a wide range of chemicals, including caustic alkalis, neutral and alkaline salts, and organic compounds. Threaded flanges made from Nickel 201 are ideal for applications requiring high purity, corrosion resistance, and where welding is not possible or desirable.
