Abstract:

Transverse ductility of electric furnace air melt and vacuum arc remelt H-11 steels, strength range 280 to 300 Ksi, was compared by means of statistical analysis of 4127 sets of tensile test data obtained from six mills and contractors records. Analysis of the data, representing 502 heats, established that remelt material 1 exhibits a superior strength-ductility relationship in all billet sizes of each mill, irrespective of test location, and 2 displays a greater uniformity of properties. Findings were augmented by contractor tests above 300 Ksi. Author
