This specification discusses nickel-iron-chromium-molybdenum-copper alloys (UNS N08825 and UNS N08221) seamless pipe and tube that has been cold-worked or hot-finished and will be used for general corrosive service. The product’s chemical composition limits such as nickel, chromium, iron, manganese, carbon, copper, silicon, sulfur, aluminum titanium, and molybdenum must adhere to the chemical requirements of this specification. Tensile strength, yield strength and elongation of the material must also adhere to the requirements for seamless pipe and tube. Additionally, the product must endure hydrostatic and nondestructive electric tests.
