1. Scope 1.1 This specification2 covers chromium, chromiumnickel, and chromiummanganesenickel stainless steel plate, sheet, and strip for pressure vessels and for general applications including architectural, building, construction, and aesthetic applications
‘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, Designation: A240/A240M - 23 Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications’ ‘This standard is issued under the fixed designation A240/A240M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision A number in parentheses indicates the year of last reapproval A superscript epsilon (e) indicates an editorial change since the last revision or reapproval This standard has been approved for use by agencies of the U.S, Department of Defense Referenced Documents Scope* 1.1 This specification? covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications including architectural, building, construction, and aesthetic applications 1.2 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 1.3 This specification is expressed in both inch-pound and SI units However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished in inch-pound unit: 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use 1.5 This international standard was developed in acco dance 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 n is under the jurisdiction of ASTM Committee AOI on Steel, Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.17 øn Flat-Rolled and Wrought Stainless Steel Current edition approved March 1, 2023 Published June 2023 Originally approved in 1940 Last previous edition approved in 2022 as A240/A240M — 22b DOI: 10.1520/A0240_A0240M>For ASME Boiler and Pressure Vessel Code applications see related Specification SA-240 in Section II of that Code, 2.1 ASTM Standards:* A370 Test Methods and Definitions for Mechanical Testing of Steel Products A480/A480M Specification Flat-Rolled Stainless and for General Requirements Heat-Resisting Steel for Plate, Sheet, and Strip A923 Test Methods for Detecting Detrimental Intermetallic Phase in Duplex Austenitic/Ferritic Stainless Steels A1084 Test Method for Detecting Detrimental Phases in Lean Duplex Austenitic/Ferritic Stainless Steels E112 Test Methods for Determining Average Grain Size E140 Hardness Conversion Tables for Metals Relationship Among Brinell Hardness, Vickers Hardness, Rockwell Hardness, Superficial Hardness, Knoop Hardness, Scleroscope Hardness, and Leeb Hardness E527 Practice for Numbering Metals and Alloys Unified Numbering System (UNS) in the 2.2 SAE Standard:* J 1086 Practice for Numbering Metals and Alloys (UNS) General Requirements 3.1 The following requirements for orders for material furnished under this specification shall conform to the applicable requirements of the current edition of Specification A480/A480M 3.1.1 Definitions, 3.1.2 General requirements for delivery, 3.1.3 Ordering information, 3.1.4 Process, *For referenced ASTM standards, visit the ASTM website, www.astm.org, or contact ASTM Customer Service at service @astm.org For Annual Book of ASTM Standards volume information, refer to the standard’s Document Summary page on the ASTM website * Available from SAE International (SAE), 400 Commonwealth Dr., Warrendale, PA 15096, htp://www.sae.org *A Summary of Changes section appears at the end of this standard Copyright © ASTM Intemational, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959 United States fly azao/az4om - 23 3.1.5 Special tests, 5.2 When specified by the purchaser, Charpy impact tests shall be performed in accordance with Supplementary Requirement S1 3.1.9 Number of tests/test methods, -10 Specimen preparation, strength shall be measured and reported in accordance Supplementary Requirement S3 .12 Inspection, Materials for High-temperature Service 14 Material test report, 6.1 The austenitic H Types shall conform to an average grain size of ASTM No or coarser as measured by Test 3.1.6 Heat treatment, 3.1.7 Dimensions and permissible variations, 3.1.8 Workmanship, finish and appearance, 5.3 When -I1 Retreatment, -13 Rejection and rehearing, -15 Certification, and 4.1 The steel shall conform to the requirements as to chemical composition specified in Table | and shall conform to specified in Specification the purchaser, % offset yield with 6.2 Supplementary Requirement S2 shall be invoked when non-H grade austenitic stainless steels are ordered for ASME Code applications for service above 1000 °F [540 °C] Chemical Composition requirements by Methods E112 -16 Packaging, marking, and loading applicable A480M specified 6.3 Grade $31060, unless otherwise specified in the purchase order, shall conform to an average grain size of ASTM No or coarser, as measured by Test Methods E112 A480/ Keywords Mechanical Properties 7.1 5.1 The material shall conform to the mechanical properties architectural;
