The Ductile Iron Marketing Group (DIMG), North Olmsted, OH, has made available the following SAE technical paper: "Monotonic and Cyclic Property Design Data for Ductile Iron Castings," J. M. Tartaglia, et. al. The purpose of the study described in the paper was to determine property data for the entire range of SAE Grade D5506 ductile iron. Eight different samples of the iron were tested to cover the full range of hardness within this grade.
