A number in parenthes
2、es indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial 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 specification establishes the requirements forcopper-nickel alloy
3、castings with nominal compositions shownin Table 1. These are as follows:2Copper Alloy UNS No.2Previous DesignationC96200 Alloy AC96400 Alloy B1.2 Castings of these alloys are used primarily forcorrosion-resistance applications such as in construction andfor pressure vessels, particularly in marine
4、pumps, valves, andfittings.1.3 These alloys are considered weldable, but they may beordered with a weld test to ensure weldability. When extensivewelding is to be performed on the casting, weldability testsshould be specified in the ordering information (4.2.6)toensure proper welding characteristics
5、.1.4 UnitsValues stated in inch-pound units are to beregarded as standard. The values given in parentheses aremathematical conversions to SI units, which are provided forinformation only and are not considered standard.1.5 The following hazard statement applies only to Section7, Weldability Test, of
6、 this specification. This standard does notpurport to address all of the safety concerns, if any, associatedwith its use. It is the responsibility of the user of this standardto establish appropriate safety and health practices anddetermine the applicability of regulatory limitations prior touse.2.
