Abstract:
A hot-rolled steel strip product having a tensile strength (Rm) above 1400 MPa and a microstructure comprising at least 90 % by volume of martensite. The steel has a composition comprising, in percent by weight (wt.-%): C 0.20 – 0.26, Si 0.05 – 0.5, Mn 0.2 – 0.8, Cr 0.2 – 0.6, Ni 0.2 – 0.5, Al 0.015 – 0.065, Ti 0.005 – 0.02, B 0.001 – 0.005, optionally Mo
