Low-Alloy Structural Steels

In view of the fact that this Symposium is sponsored by a civil engineering society, the word, structural, in the title of this paper is to be construed as pointing with strong emphasis to framed static structures, such as bridges and buildings, almost to the exclusion of small moving structures and machinery. The other papers in Section II enumerate adequately the more restricted opportunities for over-all economy which are offered to the special high-strength steels in this restricted field of application. Information has been presented to show how the economical expenditure of the steel dollar may still call for the purchase of special steels that differ from common structural steel by having enhanced mechanical properties secured through the incorporation of alloying elements.
