Standard Specification for UNS N06002, UNS N06230, UNS N12160, and UNS R30556 Rod
SCOPE
1.1 This specification covers alloys UNS N06002, UNS N06230, UNS N12160, and UNS R30556* in the form of rod for heat resisting and general-corrosive service.
1.2 The following products are covered under this specification:
1.2.1 Rods 5/16to ¾ in. (7.94 to 19.05 mm) exclusive in diameter, hot or cold finished, solution-annealed, and pickled or mechanically descaled.
1.2.2 Rods ¾ to 3½ in. (19.05 to 88.9 mm) inclusive in diameter, hot or cold finished, solution annealed, ground, or turned.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
