A large number of high-strength, low-alloy HSLA steels have been developed, and most have been marketed under proprietary names. Frequently, a steel of given composition will have several different proprietary names, or tradenames, depending upon the steel company that produced it. Thus, there are several hundred proprietary names for the large number of HSLA steels now available. For promotional purposes, different types of higher strength constructional steels have been denoted as weathering steels, microalloyed steels, controlled-rolled steels, acicular-ferrite steels, high-formability steels, and so on, the terms describing some characteristic of the type of steel or its processing. However, all hot-rolled steels of these various types are high-strength, low-alloy steels, and they are the subject of this report, which describes the development of HSLA steels, the physical metallurgy of the strengthening processes used, the characteristics of the steels, and their use.
