This specification covers nickel (UNS N02200), low carbon nickel (UNS N02201), and solution strengthened nickel (UNS N02211) in the form of hot-worked, cold-worked, or annealed rods and bars of round, square, hexagonal, or rectangular solid section. The material shall conform to the chemical composition limits specified for nickel, copper, iron, manganese, carbon, silicon, and sulfur. Mechanical requirements including tensile strength, yield strength, and elongation are given for specific conditions and diameter or distance between parallel surfaces. Chemical analysis, tension test, and hardness test shall be performed.
