A method to manufacture a hot-rolled high-strength steel sheet or strip with tensile strength of 570 MPa or higher, or preferably 780 MPa or higher, or even more preferably 980 MPa or higher, with an excellent combination of tensile elongation, SFF, and PEF strength.

Method of producing a hot-rolled high-strength steel with excellent stretch-flange formability and edge fatigue performance

A hot-rolled high-strength steel strip or sheet with excellent roll-forming characteristics and excellent stretch-flange formability suitable for automotive chassis part or the like and, more particularly, to a high-strength steel strip or sheet with tensile strength of 780 MPa or higher, or preferably 950 MPa or higher, with an excellent combination of total elongation, stretch-flange formability and fatigue resistance and to a method of manufacturing the steel strip or sheet, and to the use of the strip or sheet in a part.

Hot-rolled high-strength roll-formable steel sheet with excellent stretch-flange formability and a method of producing said steel

A high-strength hot-rolled steel strip or sheet with tensile strength of 570 to 870 MPa and an excellent combination of total elongation, stretch-flange formability, as well as fatigue resistance and to a method of manufacturing the steel strip or sheet and a chassis part made thereof.

High-strength hot-rolled steel strip or sheet with excellent formability and fatigue performance and a method of manufacturing said steel strip or sheet

A high strength hot rolled steel sheet with an excellent combination of tensile strength of at least 550 MPa and formability, including weight percent wherein the steel sheet has a precipitation strengthened and substantially single-phase ferritic microstructure, wherein the volume fraction of the ferrite phase in said microstructure is not lower than 97%, and wherein the precipitates in the microstructure comprise fine precipitates of composite carbides containing Mo and V and optionally Nb.
