1、Designation: B138/B138M 11 (Reapproved 2017)Standard Specification forManganese Bronze Rod, Bar, and Shapes1This standard is issued under the fixed designation B138/B138M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of

2、 last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification establishes the requirements for man-ganese bronze rod, bar and shapes produced in Copper AlloyUN

3、S Nos. C67000, C67500, or C67600.1.2 UnitsThe values stated in inch-pound units or SI unitsare to be regarded separately in the standard. Within the text,the SI values are shown in brackets. The values stated in eachsystem of units may not be exact equivalents; therefore, eachsystem shall be used in

4、dependently of the other. Combiningvalues from the two systems may result in nonconformancewith the standard.1.3 WarningMercury has been designated by many regu-latory agencies as a hazardous material that can cause seriousmedical issues. Mercury, or its vapor, has been demonstrated tobe hazardous t

5、o health and corrosive to materials. Cautionshould be taken when handling mercury and mercury contain-ing products. See the applicable product Safety Data Sheet(SDS) for additional information. Users should be aware thatselling mercury and/or mercury containing products into yourstate or country may
