Abstract

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.
