Standard Specification for
Steel Castings, Carbon, Suitable for Fusion Welding, for
High-Temperature Service
适合于熔接焊和高温条件的碳素钢铸件的标准规范
1: Scope/范围
1.1 This specification covers carbon steel castings for valves, flanges, fittings, or other
pressure-containing parts for high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by fusion welding.
本规范覆盖了用于高温条件的、且与其他铸件或锻钢件可以熔接装配的阀门、法兰、配件或其他承压件的碳素钢铸件。
1.2 Three grades, WCA, WCB, and WCC, are covered in this specification. Selection will
depend upon design and service conditions, mechanical properties, and the high temperature characteristics.
本规范包含WCA, WCB 和WCC三个等级的铸件。应根据设计和使用条件,机械性能和高温特性进行选择。
akgk2711.3 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 are not exact equivalents; therefore, each system must be used
independently of the other. Combining values from the two systems may result in
nonconformance with the specification.
用英寸/磅或SI单位标定的数值被看作是不同的标准。本规范中,SI单位记录在括号中。
用每个体系标识的数值不是完全相同的;因此,每个体系必须单独使用。结合使用两个体系标识的数值可能导致与规范的不相符。
