Abstract
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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
