Active Standard ASTM B369 | Developed by Subcommittee: B05.05
Book of Standards Volume: 02.01
Historical (view previous versions of standard)
1.1 This specification establishes the requirements for copper-nickel alloy castings with nominal compositions shown in Table 1. These are as follows:
|Copper Alloy UNS No.||Previous Designation|
1.2 Castings of these alloys are used primarily for corrosion-resistance applications such as in construction and for pressure vessels, particularly in marine pumps, valves, and fittings.
1.3 These alloys are considered weldable, but they may be ordered with a weld test to ensure weldability. When extensive welding is to be performed on the casting, weldability tests should be specified in the ordering information (5.2.6) to ensure proper welding characteristics.
1.4 Units—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.
1.5 The following hazard statement applies only to Section 8, Weldability Test, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
