Scattered throughout the literature are many reports of studies of transverse tests on cast-iron beams of various sizes and cross-sectional form. In many instances the test bars were used in the “as-cast” condition, while the nature of the cast iron used was such as to defy both understanding and interpretation of the test results with any degree of accuracy. There are two basic reasons for this: 1. The term gray cast itself covers a field of many materials varying in both chemical and physical properties. 2. The methods of testing used were often crude and inaccurate. Since new tools of high precision are available today both in the manufacture of cast iron to controlled structural and physical properties, and in the method of testing; advantage of these has been taken in this investigation.
