Abstract
Described is a hot-rolled steel having a tensile strength of at least 950 MPa and a microstructure that includes bainite at an area ratio of 70% or more; the balance being: martensite at an area ratio of 30% or less, and optionally ferrite at an area ratio of 20% or less. The hot-rolled steel has a chemical composition containing (in mass-%): C: 0.07-0.10, Si: 0.01-0.25, Mn: 1.5-2.0, Cr: 0.5-1.0, Ni: 0.1-0.5, Cu: 0.1-0.3, Mo: 0.01-0.2, Al: 0.01-0.05, Nb: 0.015-0.04, V: 0-0.1, i.e. optionally up to 0.1 mass-% Vanadium, Ti: 0-0.1, whereby the balance is Fe and unavoidable impurities.
