1、Designation:A487/A487M141Standard Specification forSteel Castings Suitable for Pressure Service1This standard is issued under the fixed designation A487/A487M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.
2、A number in parentheses indicates the year of last reapproval.A superscript epsilon()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.1NOTETable 1 was corrected editorially in June 2017.1.Scope*1.
3、1 This specification2covers low-alloy steels and marten-sitic stainless steels in the normalized and tempered,orquenched and tempered,condition suitable for pressure-containing parts.The weldability of the classes in this speci-fication varies from readily weldable to weldable only withadequate prec
4、autions,and the weldability of each class shouldbe considered prior to assembly by fusion welding.1.2 Selection will depend on design,mechanical,and ser-vice conditions.Users should note that hardenability of someof the grades mentioned may restrict the maximum size atwhich the required mechanical p
5、roperties are obtained.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in n
