The plates, as represented by the tension test specimens, shall conform to the mechanical property requirements.1.1 This specification2 covers high-tensile strength carbon-manganese steel plates intended for welded pressure vessels.1.2 This steel is usually made to a semi-killed or capped deoxidation practice; however, at the purchaser's or the steel producer's option, the steel may be made silicon-killed or aluminum-killed.1.3 The maximum thickness of plates furnished under this specification shall be 3/4 in. [20 mm].1.4 For plates produced from coil and furnished without heat treatment or with stress relieving only, the additional requirements, including additional testing requirements and the reporting of additional test results, of Specification A20/A20M apply.1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.1.6 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.

This specification establishes the requirements for rods, bars, and shapes of manganese bronze with Copper Alloy UNS Nos. C67000, C67500, and C67600. The materials for manufacture shall be cast billets of such purity and soundness as to be suitable for processing by hot working (extrusion, forging, or rolling) to produce a uniform wrought structure in the finished product. Tempers available under this specification are O60 (soft anneal temper), M20 (as hot rolled temper), M30 (as hot extruded temper), H02 (half-hard temper), and H04 (hard temper). Products shall be tested (including by residual stress test and ammonia vapor test) and shall adhere to dimensional (diameter, width, thickness, shape, length, straightness, and edge contour), mechanical (tensile and yield strength, and elongation), and chemical composition requirements.1.1 This specification establishes the requirements for manganese bronze rod, bar and shapes produced in Copper Alloy UNS Nos. C67000, C67500, or C67600.1.2 Units—The values stated in inch-pound units or SI units are to be regarded separately in the standard. Within the text, the SI values are shown in brackets. The values stated in each system of units may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.3 Warning—Mercury has been designated by many regulatory agencies as a hazardous material that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Safety Data Sheet (SDS) for additional information. Users should be aware that selling mercury and/or mercury containing products into your state or country may be prohibited by law.NOTE 1: Product suitable for hot forging applications is available under Specification B124/B124M.1.4 The following safety hazard caveat pertains only to the Performance Requirements section of this specification.1.4.1 This standard does not purport to address all of the safety concerns, if any, associated with its use.
