3、ial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification2covers carbon steel castings forvalves, flanges, fittings, or other pressure-containing parts forhigh-temperature service and of quality s

4、uitable for assemblywith other castings or wrought-steel parts by fusion welding.1.2 Three grades, WCA, WCB, and WCC, are covered inthis specification. Selection will depend upon design andservice conditions, mechanical properties, and the high tem-perature characteristics.1.3 The values stated in e

5、ither 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.
