Scope*1.1 This specification2covers carbon steel castings forvalves, flang
4、es, fittings, or other pressure-containing parts forhigh-temperature service and of quality suitable 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
5、, mechanical properties, and the high tem-perature characteristics.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. Comb
