1. Scope
1.1 This speci fication covers chromium-molybdenum- vanadium alloy steel plates intended primarily for the fabrica- tion of welded pressure vessels. 1.2 The plates furnished under this specification are re- quired to be normalized-and-tempered. Specification A542/ A542M includes coverage of the material in the quenched-and- tempered condition. 1.3 The maximum thickness of plates furnished to this specification is limited only by the capacity of the composition to meet the specified property requirements. 1.4 The material is intended to be suitable for fusion welding. Welding technique is of fundamental importance and it is presupposed that welding procedures will be in accordance with approved methods. 1.5 This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the mate- rial shall be furnished to inch-pound units. 1.6 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 1.7 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. General Requirements and Ordering Information
3.1 Material supplied to this material specification shall conform to Specification A20/A20M. These requirements out- line the testing and retesting methods and procedures, permis- sible variations in dimensions, quality and repair of defects, marking, loading, and ordering information. 3.2 In addition to the basic requirements of this 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. 3.3 If the requirements of this specification are in conflict with the requirements of Specification A20/A20M, the require- ments of this specification shall prevail.
5. Heat Treatment
5.1 All plates shall be normalized and tempered except as allowed by 5.2. The minimum normalizing temperature for Grade 22V shall be 1650°F [900°C]. The minimum normaliz- ing temperature for Grade 23V shall be 1850°F [1010°C]. The minimum tempering temperature shall be 1250°F [675°C]. 5.2 Plates ordered without the heat treatment required by 5.1 shall be furnished in either the stress-relieved or the annealed condition. Heat treatment of plates so ordered, to conform to 5.1 and to Table 1, shall be the responsibility of the purchaser.
6. Chemical Composition
6.1 The steel shall conform to the requirements as to chemical composition shown in Table 2.
7. Mechanical Properties
7.1 Tension Test Requirements: 7.1.1 The material as represented by the tension test speci- mens shall conform to the requirements of Table 1. . 7.2 Notch Toughness Requirements: 7.2.1 A transverse Charpy V-notch test from each plate as . heat-treated shall have a minimum energy absorption value of 40 ft.lbf [54 J] average of three specimens and 35 ftIbf [48 J] for one specimen only in the set. 7.2.2 The notch toughness test temperature shall be 0°F . [- 18°C].
