ASTM WK44378

    Revision of B271 / B271M - 11e1 Standard Specification for Copper-Base Alloy Centrifugal Castings

    (What is a Work Item?)

    Active Standard: B271 / B271M - 14a

    Developed by Subcommittee: B05.05 | Committee B05 | Contact Staff Manager



    WK44378

    1. Rationale

    The elongation property of alloy C93700 is 15% for products produced by sand casting as specified in the ASTM B584. The elongation property of the same alloy, C93700 is also 15% for products produced by centrifugal casting per ASTM B271. The suppliers of the centrifugal casting are having difficulty to achieve 15% elongation. It is recommended by the suppliers that the elongation property be changed from 15% to 10% to make the alloy more manufactureable and reduce scrap rate for the centrifugal casting products.
