(Specification)Standard Specification for Stainless Chromium Steel-Clad Plate
Standard Specification for Stainless Chromium Steel-Clad Plate
ABSTRACT
This guide covers standard specification for a carbon steel plate or a low-alloy steel base to which is integrally and continuously bonded on one or both sides of a layer of stainless chromium steel. The steel shall be made by open-hearth, electric-furnace, or basic-oxygen process, or by secondary processes whereby steel made from these primary processes is remelted using, but not limited to electroslag remelting or vacuum-arc remelting processes. The steel plate may be heat-treated after the forming process. Tensile properties shall be determined by a tension test of the composite plate for clad plates that meet the specified values of tensile strength and yield strength. The composite plate shall conform to any desired combination of alloy-cladding metal and base metal. Tests for strength of the bond, when required, shall be performed and shall meet the specified values of shear and bond strengths. The test specimen shall undergo one or more tension tests, as required by the specifications for the base metal and, when specified, one shear test or three bond bend tests shall be made representing each plate as rolled. Product analysis may also be required for the cladding alloy on the finished product.
SCOPE
1.1 This specification2 covers 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 stainless chromium steel. The material is generally intended for pressure vessel use.
1.2 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.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
