This paper discusses the principles involved in the design of steel castings, the characteristics of which are advantageous from both an engineering and an economic point of view. The responsibility for quality, soundness, strength, and serviceability rests not in the foundry but with the designer. Most designers, however, have little experience with casting design. The basic design rules, which are based upon the laws of chemistry and physics, are thus presented as well as a description of testing techniques, various properties, and behavior under specific service conditions. It is through the close cooperation of the knowledgeable designer with the foundryman that ultimately the optimum design results.
