Annotation of standard text 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.
