ASTM B61-15

Standard Specification for Steam or Valve Bronze Castings

ABSTRACT
This specification establishes requirements for a high-grade steam-metal or valve-bronze alloy (Copper Alloy UNS C92200) used for component castings of valves, flanges, and fittings. Tensile strength, yield strength, and elongation shall be determined from separately cast test bars and shall meet the specified requirements. Castings shall not be plugged, welded, burned-in, or impregnated.
SCOPE
1.1 This specification2 establishes requirements for a high-grade steam-metal or valve-bronze alloy (Copper Alloy UNS No. C922003) used for component castings of valves, flanges, and fittings.  
1.2 The castings covered are used in products that may be manufactured in advance and supplied from stock by the manufacturer or other dealer.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
