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

Abstract

Work accomplished in the initial portion of Phase IV prior to receipt of steel which will be closed-die forged into structural aircraft parts is described. Four heats of material processed by vacuum induction melting followed by vacuum arc remelting were ordered to a specification which requires an average transverse ductility of 12% reduction of area at the 300 to 330 Ksi ultimate tensile strength level. The selected melting process for Phase IV steel was chosen on the basis of its demonstrated capability in Phase III for significantly-reduced mechanical property directionality. The effects upon mechanical properties and property directionality of optimized mill processing, billet size, hot reduction variation, and closed-die forging will be statistically analyzed. (Author)
