ASTM A263-2019 pdf free download.Standard Specification for Stainless Chromium Steel-Clad Plate
1. Scope
1.1 This specification 2 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 accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions ofTerms Specific to This Standard: 3.1.1 This material is considered as single-clad or double- clad stainless chromium-steel plate, depending on whether one or both sides are covered. 3.1.2 alloy cladding, n—the stainless chromium steel com- ponent of the composite plate. 3.1.3 base metal (backing steel), n—component to which the alloy cladding is applied, usually the greater percentage of the composite plate. 3.1.4 integrally and continuously bonded, n—a condition in which the alloy cladding and base metal are brought together to form a metallurgical bond at essentially the entire interface of the two metals by means other than those processes that do not produce a homogeneous composite plate.
4. Ordering Information
4.1 It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under this specification. Such requirements may include, but are not limited to, the following: 4.1.1 Quantity (weight or number of pieces). 4.1.2 Cladding alloy specification (UNS or ASTM Specifi- cation A240/A240M) and whether cladding is for corrosion allowance only. 4.1.3 Base metal specification. 4.1.4 Bond integrity Class (1, 3, or 5; see Section 13). 4.1.5 Dimensions including the minimum or nominal thick- nesses of the cladding alloy and the backing steel, or of the total composite and if more or less restrictive thickness tolerances apply.4.1.6 Product analysis, if required (see Section 10). Specify whether applicable to the cladding alloy, backing steel, or both. 4.1.7 Mechanical properties including shear test if required (see Sections 7, 8, and 9). 4.1.8 Finish (see Section 12). 4.1.9 Restrictions, if required, on repair by welding (see Section 14). 4.1.10 Additions to the specification or special requirements such as any applicable construction code rules. 4.1.11 Notification when the cladding alloy is to be used for inclusion in the design strength calculations for an applicable construction code. N OTE 1—Construction codes may dictate certain fabrication require- ments when the cladding is used in the design calculations that may be different than if the cladding is used for corrosion resistance only. This may be particularly important when the alloy cladding involves the use of welded components in the explosion bonded clad manufacturing process. It is incumbent on the purchaser to make the clad manufacturer aware of any such restrictions or applications at time of order. 4.2 In addition to the basic requirements ofthis specification and the backing steel specification, certain supplementary requirements are available when additional control, testing, or examination is required to meet end use requirements. The purchaser is referred to the listed supplementary requirements in this specification and to the detailed requirements in Specification A20/A20M. 4.3 If the requirements of this specification are in conflict with the requirements ofSpecification A20/A20M, the require- ments of this specification shall prevail.
