Steels for Hydrospace
Abstract
Recent steel developments indicate that strength and toughness requirements for 150 ksi yield-strength steel essentially have been met, that the requirements for the 200 ksi yield-strength steel are a near-term probability, and that the requirements for the 250 ksi yield-strength steel are a long-term possibility. The most serious obstacle to meeting the full range of predictions is the attainment of high toughness in plates 6 to 8 inches thick. Thus, special designs, such as those employed in multilayer vessels, may be required for heavy-wall hydrospace vehicles. The preceding accomplishments and predictions are based on (1) the progress that has been made in the past few years in the melting of steels with greatly reduced levels of impurity elements, (2) the development of entirely new high-strength, high-toughness steel systems, and (3) the discovery of new processing techniques that greatly increase the toughness of steels.
