(Specification)Standard Specification for Cartridge Brass Sheet, Strip, Plate, Bar, and Disks
Standard Specification for Cartridge Brass Sheet, Strip, Plate, Bar, and Disks
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.
SCOPE
1.1 This specification establishes the requirements for sheet, strip, plate, bar, and disks for the manufacture of ammunition component parts thereof from alloy UNS C26000.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.
1.2.1 Exception—Values given in inch-pound units are the standard except for grain size, which is stated in SI units.
1.3 The following safety caveat pertains only to the test method described in Section 10 of this specification.
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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.)
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
