ASTM B98/B98M-13(2019)

Annotation of standard text ASTM B98/B98M-13(2019) :

This specification covers rods, bars, and shapes of copper-silicon alloys with UNS Alloy UNS Nos. C65100, C65500, and C66100. The starting materials shall be cast billets or rods of such soundness and structure as to enable them to be processed by hot working, cold working, straightening, and annealing to produce a uniform wrought structure in the finished product. Tempers available under this specification are O60 (soft annealed), H01 (1/4-hard), H02 (1/2-hard), H04 (hard), H06 (extra-hard), M20 (as hot rolled), and M30 (as hot extruded). Products shall be tested and shall adhere to dimensional (mass, diameter, shape, length, straightness, and edge contour), mechanical (tensile and yield strength, elongation, and Rockwell hardness), and chemical composition requirements.
