Source: ASTM International

This specification covers nickel-iron-chromium-molybdenum-copper alloys (UNS N08825 and UNS N08221) in the form of cold-worked and hot-finished seamless pipe and tube intended for general corrosive service. Material furnished under this specification shall conform to the applicable requirements specified. Chemical composition limits of the material such as nickel, chromium, iron, manganese, carbon, copper, silicon, sulfur, aluminum titanium, and molybdenum shall conform to the chemical requirements of this specification. Tensile strength, yield strength and elongation of the material under the specified condition and size shall also conform to the required mechanical properties. Hydrostatic and nondestructive electric tests shall be performed.
