ASTM B138/B138M-06

Standard Specification for Manganese Bronze Rod, Bar, and Shapes

ABSTRACT
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.
SCOPE
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 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.
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 limitations prior to use.
1.3 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.
