ASTM B171/B171M-09

1.1 This specification establishes the requirements for copper-alloy plate, sheet, and circles cut from plate and sheet for pressure vessels, condensers, and heat exchangers. The following alloys are covered:

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

This specification establishes the requirements for plates, sheets, and circles cut from plates and sheets made of UNS C36500, C44300, C44400, C44500, C46400, C46500, C61300, C61400, C63000, C63200, C70600, C70620, C71500, C71520, or C72200 copper alloy. These materials are recommended for use in pressure vessels, condensers, and heat exchangers. The materials are manufactured by either hot rolling or forging and finished by such cold working and annealing to produce products of the required dimensions and properties. Tempers available under this specification are as hot rolled and hot rolled and annealed. The products manufactured for ASME Boiler and Pressure Vessel code applications must be certified to the hot rolled and annealed temper while all other products can either have hot rolled or hot rolled and annealed temper. This specification also contains information on the required material chemical compositions, densities, and tensile properties.
