    Abstract

    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. The product shall be manufactured by such casting methods to produce a uniform finished product. The castings shall conform to the compositional requirements for named elements specified. The castings shall not be repaired, plugged, welded, or burned-in.
