This specification covers welded UNS N08020, N08024, and N08026 alloy boiler, heat exchanger, and condenser tubes for general corrosion-resisting and low- or high-temperature service. Tubing shall be made from flat-rolled stock by an automatic welding process with no addition of filler metal. Subsequent to welding and prior to final heat treatment, the material shall be cold-worked in either the wed metal only, or in both the weld and base metal. Tubing of UNS N0820 alloy shall be furnished in the stabilized-annealed condition, Tubing of UNS N0824 alloy shall be furnished in the annealed condition. Tubing of UNS N0826 alloy shall be furnished in the solution-annealed condition. The material shall conform to the composition limits specified. The material shall conform to the mechanical property requirements for tensile strength, yield strength and elongation. Flattening and flange tests shall be made on each end of one tube per lot.
