Abstract
This specification establishes the requirements UNS C26000 brass sheets, strips, plates, bars, and disks (blanks) that are used for the manufacture of ammunition parts like cartridge cups and disks. Each product should be manufactured by hot working, cold working, and annealing processes to produce a uniform wrought structure having the temper specified for the finished product. This specification also contains information on the prescribed tensile strength and elongation for a given thickness of annealed and as-hot rolled materials, as well as the required tensile strengths for particular rolled temper designations.
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. Scope
1.1 This specification establishes the requirements for sheet, strip, plate, bar, and disks for the manufacture of ammunition of component parts thereof from alloy UNS C26000.
1.2 Values given in inch-pound units are the standard except for grain size which is stated in metric units. SI values given in parenthesis are for information only.
The following safety caveat pertains only to the test method described in Section of this specification. 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
