This specification covers nickel-iron chromium-molybdenum alloy (UNS N08320) rod for use in general corrosive service. The rods are classified according to their sizes. The material shall conform to the composition limits specified. Chemical analysis and tension test shall be made to conform to the specified requirements.
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.
1.1 This specification covers nickel-iron chromium-molybdenum alloy (UNS N08320)* rod for use in general corrosive service.
1.2 The following products are covered under this specification:
1.2.1 Rods 5/16 to ¾ in. (7.94 to 19.05 mm) excl 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) incl 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.
