Abstract
A method of making a high-strength low-alloy (HSLA) hot rolled steel. A high-strength low-alloy steel is made by hot rolling a steel slab of a specified composition. The hot rolling step is carried out at an austenitic hot roll finishing temperature. The hot rolled steel is coiled at a temperature ranging from 1120.degree. F. to 1180.degree. F. The steel is characterized by a yield strength of at least 110 ksi. The steel may be further characterized by a ferrite-bainite microstructure.
