Download or read book Consideration of Steels with Over 150,000 Psi Yield Strength for Deep-submergence Hulls written by G. K. Manning and published by . This book was released on 1963 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three types of ferrous materials that deserve to be considered as future hull materials are discussed. The present state of knowledge can be summarized this way: quenched and tempered steels with 0.20% carbon and yield strengths of about 170,000 psi can probably be developed into a useful hull material in less time than either of the other two classes. Maraging steels have great potential if it is possible to improve their toughness. This may be resolved within a few months and surely within a year. The stable austenitic steels appear to offer the greatest potential, but less is known about these than about the other two classes of materials. (Author).
