ASTM B160 Specification

Scope

This specification2 covers nickel (UNS N02200)*, low carbon nickel (UNS N02201)*, and solution strengthened nickel (UNS N02211) in the form of hot-worked and coldworked rod and bar in the conditions shown in Table 1. The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
