Abstract

This specification covers plates made of carbon steel or low-alloy steel base, to which a layer of copper or copper-base alloy cladding is integrally and continuously bonded on one or both sides. The material is generally intended for pressure vessel applications, but may be used in other structural applications where corrosion resistance or conductivity of the alloy is of prime importance. The steel shall be primarily made by the open-hearth, electric-furnace (with optional degassing and refining done separately), or basic-oxygen processes. Secondary processes may also be performed, whereby the steel made from the primary processes is remelted using, but not limited to, electroslag remelting or vacuum arc remelting. Materials shall be tested and shall conform to dimensional (thickness, flatness, and outside diameter), mechanical (tensile, shear and bond strengths), and chemical composition requirements. The manufacturer may rework defects in the cladding by repair welding provided specific requirements are met.

This abstract is a brief summary of the referenced standard.

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 plate of a carbon steel or low-alloy steel base to which is integrally and continuously bonded on one or both sides a layer of copper or copper-base alloy. The material is generally intended for pressure vessel use but may be used in other structural applications where corrosion resistance or conductivity of the alloy is of prime importance.

1.2 Units The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
