Extensive use has been made by the gas turbine industry of centrispun castings of certain highly alloyed heat resisting steels. The paper outlines the main features of the centrispinning process and discusses the advantages that one could expect, not only in mechanical properties, but also in cost and the casting to shape in refractory molds. Results of mechanical tests on sections cut from representative castings are given and show the high order of the tensile strength to be expected.
