ASTM B66/B66M-06

1.1 This specification establishes requirements for bronze castings for steam locomotive wearing parts. The following Copper Alloy UNS Nos. are specified: C93200, C93400, C93600, C93700, C93800, C94300, C94400, and C94500.

Historically, the alloys in this specification have been used in the applications listed in the Appendix. Actual practice may vary according to locomotive type and service.

1.2 Units - The values stated in inch-pound or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
