摘要： The invention relates to a cold rolled steel strip or sheet having a composition comprising of 0.02-0-10 C, 0.6-1-2 Mn, 0.015-1.5 Al, 0.03-012 Ti, 0.01-0-.06 Nb, where Ti+ Nb is 0.05-0.15. The strip or sheet having a Yield strength (Rp0.2) of 800 -950 MPa, a Tensile strength (Rm) of 830-1000 MPa, a Total elongation (A80) ≥ 9%, and a hole expansion ratio (λ) ≥ 60 %. The invention also relates to a continuous process of producing the strip or sheet.
