Anotácia textu normy ASTM B138/B138M-11(2017) :
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.
Keywords:
manganese bronze bar, manganese bronze rod, manganese bronze shape, UNS No. C67000, UNS No. C67500, UNS No. C67600,, ICS Number Code 77.150.30 (Copper products)

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 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. |
