Standard Specification for Nickel Rod and Bar
1.1 This specification covers nickel (UNS N02200)*, low carbon nickel (UNS N02201)*, and solution strengthened nickel (UNS N02211) in the form of hot-worked and cold-worked rod and bar in the conditions shown in Table 1.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
