Modern Cast Iron

Abstract

FEW metallurgical products have shown such a marked improvement in quality during the last two decades as have the cast irons. So rapid has this advance been, that few, except those in Immediate contact with the industry, can have kept abreast of the work done; and the engineer user has perforce lagged behind in his knowledge of the new materials thus placed at his disposal. It was presumably in appreciation of this fact that the Institution of Mechanical Engineers formed a Research Committee on High Duty Cast Irons for General Engineering Purposes, the first report of which was published in 1938. This was concerned with a general outline of the development of both the “high–duty” irons used on account of their enhanced strength, and of the special–duty irons employed in the main as a result of their possession of unusual physical or chemical properties.
