EVALUATION OF MISCELLANEOUS EXPERIMENTAL HY-130/150 STEELS.

Abstract

The experimental HY-130/150 steels investigated consist of three Mn-Ni-Cr-Mo steels, three 5 1/4- to 7 1/2percent-nickel steels, four 5Ni-Cr-Mo steels, and two HY-80 steels. The results of the evaluation of the twelve steels indicated that none of the steels was particularly attractive as an HY-130/150 steel and that each steel exhibited one or more shortcomings, such as inadequate hardenability, low strength, poor notch toughness, or lack of sufficient resistance to softening on tempering. However, the studies did show that a reduction in the carbon, manganese, and/or sulfur content significantly improved the notch toughness of the 5Ni-Cr-Mo steels. However, compensating alloy additions must be made to offset the loss in hardenability when carbon and manganese are reduced. (Author)
