DEVELOPMENT AND STATISTICAL ANALYSIS EVALUATION OF MELTING AND TRANSVERSE PROPERTIES OF HIGH STRENGTH (H-11 TYPE) STEEL

Abstract

Four vacuum arc remelt (VAR) process variations commercially available for the production of high-strength steel were statistically compared in terms of smooth and notch tensile test data developed from transverse and longitudinal specimens removed from 10-in. RCS press-forged billets. Of the four processes, (1) air melt- VAR, (2) air melt-degas-VAR, (3) air melt-double VAR, and (4) vacuum induction melt-VAR, in vestigated at a 300 Ksi ultimate strength level, the vacuum induction melt-VAR process provided the highest ductility and the most nearly uniform transverse and longitudinal strength and ductility. The air melt-VAR material ranked second in over-all property response and uniformity, although significantly lower than that provided by the vacuum induction melt-VAR process. Air melt-degas-VAR and air melt-double VAR processes ranked third and fourth, respectively, but were not significantly different when compath air melt-VAR property data.
