Abstract: A method for producing an ultra-high-strength hot-rolled structural steel includes producing a steel alloy with a carbon content not greater than 0.2%, avoiding a diffusive transformation of the austenite by achieving a transformation delay through the addition of manganese, chromium, and boron, and casting the steel alloy. The cast steel alloy is heated and hot rolled to form a steel strip which is then immediately hardened and mechanically straightened to produce mobile dislocations, wherein the boron, manganese and chromium delay diffusive transformation from an austenite structure to achieve formation of a martensite structure during the hardening. The steel strip is then annealed at a temperature between 100 and 200° C.
