ASTM B140 / B140M

This specification establishes the requirements for copper-zinc-lead (leaded red brass or hardware bronze) rods, bars, and shapes of UNS Alloy Nos. C31400, C31600, and C32000 used for screw machine applications. Tempers available to this specification are O60 (soft anneal), H02 (half-hard), and H04 (hard). Materials for manufacture shall be cast billets, logs, or rods of such purity and soundness as to be suitable for processing 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 anneal), H02 (half-hard), and H04 (hard). Products shall be tested and conform to dimensional (mass, diameter, length, straightness, and shape), mechanical (tensile and yield strength, and elongation), and chemical composition requirements.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification establishes the requirements for copper-zinc-lead (leaded red brass or hardware bronze) rod, bar, and shapes of UNS Alloy Nos. C31400, C31600, and C32000 available for screw machine applications.

1.2 Units—The values stated in inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
