1、Designation: A553/A553M 14A553/A553M 17Standard Specification forPressure Vessel Plates, Alloy Steel, Quenched andTempered 7, 8, and 9 % Nickel1This standard is issued under the fixed designation A553/A553M; the number immediately following the designation indicates the yearof original adoption or,
2、in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification2 covers 7, 8, and 9 % nickel alloy steel plates for use in th
3、e water quenched and tempered conditionintended for the fabrication of welded pressure vessels.1.2 Material under this specification is available in three types having different chemical composition as follows:Type Nominal Nickel Content, %I 9II 8III 71.3 Plates produced under this specification are
4、 subject to impact testing at 320F 195C for Type I or Type III, and 275F170C for Type II; or at such other temperatures as are agreed upon.1.4 The maximum thickness of plates is limited only by the capacity of the material to meet the specified mechanical propertyrequirements; however, current mill
5、practice normally limits this material to 2 in. 50 mm max.1.5 This material is susceptible to magnetization. Use of magnets in handling after heat treatment should be avoided if residualmagnetism would be detrimental to subsequent fabrication or service.1.6 The values stated in either inch-pound uni
6、ts or SI units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be usedindependently of the other. Combining values from the two systems may result in nonconformance
