This specification covers UNS N08020, UNS N08026 and UNS N08024 nickel-alloy seamless, cold-worked or hot-finished pipe and tube intended for general corrosive service. The product of UNS N08020 alloy, UNS N08026 alloy, and UNS N08024 alloy shall be furnished in the stabilized-annealed condition, solution-annealed condition, and annealed condition, respectively. The tensile strength, yield strength, and elongation requirements are specified. Hydrostatic and nondestructive electric tests shall be conducted on the each pipe or tube.
