PRELIMINARY TESTS TO DETERMINE THE FATIGUE STRENGTH OF DEFECTIVE STEEL CASTINGS

Little information is available on the relationship between defects and the fatigue strength of steel castings. Some preliminary fatigue tests were therefore carried out on steel castings which had been rejected on radio-graphic evidence of shrinkage porosity. The tests showed that the fatigue strength would probably have been adequate for the intended application. Failure in the castings originated at defects but little correlation was found between the radiographs and the origin of failure. It is suggested that a classification scheme for the fatigue strength of steel castings, similar to those already in use of weldments, should be drawn up.
