METHOD FOR MANUFACTURING HOT ROLLED STEEL STRIP PRODUCT, AND HOT ROLLED STEEL STRIP PRODUCT

The invention relates to a method for manufacturing a hot-rolled steel strip product with a thickness of 2 - 12 mm from low-alloy steel having a carbon content of 0.04 - 0.08 in percentage by weight and containing niobium and titanium. In order to obtain good mechanical properties, with bending properties included, for the steel strip product, a work piece of steel is austenized at an austenizing temperature of 1200 - 13500C, the steel work piece is hot-rolled at a pre-rolling step, the pre-rolled steel work piece is rolled in a strip roll mill so that a rolling temperature of 760 - 9600C is achieved for the work piece in the last pass, and the steel strip is direct quenched after the last pass in the strip roll mill by a single-step cooling at a cooling rate of 30 - 150°C/s to a temperature of 3000C at the most, the direct quenching being carried out within 15s from the last pass. The invention also relates to a steel strip product.
