This specification2 covers alloys UNS N06002, UNS N06230, UNS N12160, and UNS R30556* in the form of rod for heat resisting and general-corrosive service. The following products are covered under this specification: Rods 5⁄16 to 3⁄4 in. (7.94 to 19.05 mm) exclusive in diameter, hot or cold finished, solution-annealed, and pickled or mechanically descaled. Rods 3⁄4 to 31⁄2 in. (19.05 to 88.9 mm) inclusive in diameter, hot or cold finished, solution annealed, ground, or turned. The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
