ASTM B 138-B 138M-06

Designation: B 138/B 138M – 06 Standard Specification for Manganese Bronze Rod, Bar, and Shapes1 This standard is issued under the fixed designation B 138/B 138M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. 1. Scope* 1.1 This specification establishes the requirements for man- ganese bronze rod, bar and shapes produced in Copper Alloy UNS Nos. C67000, C67500, or C67600. 1.2 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 given in brackets. The values stated in each system of units are not exact equivalents; each system is independent of the other. Combining values from the two systems may result in nonconformance with the specification. 1.3 The following safety hazard caveat pertains only to the Performance Requirements 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 limita- tions prior to use. 1.4 Warning—Mercury is a definite health hazard in use and disposal. NOTE 1—Product suitable for hot forging applications is available under Specification B 124/B 124M. 2.

Material and Manufacture 5.1 Material—The material of manufacture shall be cast billets of Copper Alloy UNS No. C67000, C67500, or C67600 as specified in the ordering information, and shall be of such purity and soundness as to be suitable for hot working. 5.2 Manufacture: 5.2.1 The product shall be manufactured by hot working (extrusion, forging, or rolling) to produce a uniform wrought structure in the finished product. 5.2.2 The product shall be finished by such cold working, annealing, and straightening as may be necessary to achieve the required properties. 6. Chemical Composition 6.1 The material shall conform to the chemical composition requirements in Table 1 for the Copper Alloy UNS No. specified in the ordering information. 6.1.1 These compositional limits do not preclude the pres- ence of other elements. By agreement between the manufac- turer and the purchaser, limits may be established and analysis required for unnamed elements. 6.2 For copper alloys in which zinc is specified as the “remainder,” either copper or zinc may to be taken as the difference between the sum of results for all elements deter- mined and 100 %. When copper is so determined, that differ- ence value shall conform to the requirements given in Table 1. 6.2.1 When all elements in Table 1 are determined, the sum of results shall be 99.5 % min. 7. Temper 7.1 The standard tempers for products described in this specification are given in Tables 2 and 3. 7.1.1 Soft Anneal Temper (O60), 7.1.2 As Hot Rolled Temper (M20), 7.1.3 As Hot Extruded Temper (M30), 7.1.4 Half-Hard Temper (H02), and 7.1.5 Hard Temper (H04). 8. Mechanical Property Requirements 8.1 Tensile Requirements: 8.1.1 The product furnished under this specification shall conform to the tensile requirements prescribed in Table 2 or Table 3 when tested in accordance with Test Methods E 8 or E 8M. 9. Performance Requirements 9.1 Residual Stress Test: 9.1.1 When specified in the contract or purchase order, the product shall be tested for residual stress according to the requirements of Test Method B 154 or Test Method B 858 and show no signs of cracking. (Warning—Mercury is a definite health hazard. With the mercurous nitrate test, equipment for the detection and removal of mercury vapor produced in volatilization is recommended. The use of protective gloves for this test is recommended.) 9.1.2 When the ammonia vapor test is used, the test pH value appropriate for the intended application shall be 10 unless otherwise specified by the purchaser. NOTE 2—A residual stress test provides information about the adequacy of the stress relief of the material. Bar straightening is a method of mechanical stress relief. Stress relief annealing is a method of thermal stress relief. 9.2 Piston Finish—When specified in the contract or pur- chase order, round rod over 0.500 in. [13 mm] in diameter shall be furnished piston finish. 10. Purchases for U.S. Government 10.1 Product purchased for agencies of the U.S. government shall conform to the additional requirements prescribed in the Supplementary Requirements section of Specification B 249/ B 249M. 11.
