This specification covers nickel-iron-chromium alloys in the form of welded, cold-worked, and annealed pipe for general corrosive service and heat resisting applications. These products are furnished three alloys: UNS N08120, UNS N0880, and UNS N08810. The materials shall conform to the required chemical composition for nickel, chromium, iorn, manganese, carbon, copper, silicon, sulfur, aluminum, titanium, columbium, molybdenum, phosphorus, tungsten, cobalt, and nitrogen. The materials shall conform to the requred mechaniical properties such as tensile strength, yield strength, and elongation. A transverse sample representing the full wall thickness of annealed alloys UNS N08120 and N08810 shall conform to the average grain size. Pipe shall be capable of withstanding, without cracking, flattening under a load applied gradually. Each piece of each lot shall be subjected to hydrostatic test, pneumatic test, eddy current test, ultrasonic test, leak test, electric test, and transverse guided bend test.
