This specification covers nickel-chromium-iron-molybdenum-copper alloy rods (UNS N06007, N06975, N06985, N06030, and N08031), hot- or cold-finished, solution annealed, ground, or turned, for use in general corrosive service. Heat and product (check) analysis of the alloy shall conform to the chemical composition requirements prescribed for nickel, chromium, iron, molybdenum, copper, manganese, cobalt, carbon, tungsten, silicon, phosphorus, sulfur, columbium and tantalum, titanium, and nitrogen. The material shall conform to the specified straightness criteria and to the mechanical property requirements including tensile strength, yield strength, and elongation, as determined by tension test.

1.1 This specification² covers rod of Ni-Cr-Fe-Mo-Cu alloys (UNS N06007, N06975, N06985, N06030, and N08031)* as shown in Tables 1-3, for use in general corrosive service.
