STANDARD SPECIFICATION FOR STEAM OR VALVE BRONZE CASTINGS
|Publication Date:||27 July 1990|
|ICS Code (Copper products):||77.150.30|
This specification2 covers a high-grade steam-metal or valve-bronze alloy (Copper Alloy UNS No. C922003) used for component castings of valves, flanges, and fittings.
The values stated in inch-pound units are to be regarded as the standard.
2 For ASME Boiler and Pressure Vessel Code applications see related Specification SB-61 in Section II of that Code.
3 The UNS system for copper and copper alloys (see Practice E 527) is a simple expansion of the former standard designation system accomplished by the addition of a prefix "C" and a suffix "00." The suffix can be used to accommodate composition variations of the base alloy.
