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.
