Abstract (en)

[origin: US2006207692A1] The invention relates to ultrahigh strength hot-rolled steel having a chemical composition consisting of, by weight: 0.05%=C=0.1%, 0.7%=Mn=1.1%, 0.5%=Cr=1%, 0.05%=Si=0.3%, 0.05=Ti=0.1%, Al=0.07, S=0.03%, P=0.05, the remainder comprising iron and impurities resulting from the production thereof. Moreover, the inventive steel has a bainitic-martensitic structure which can contain up to 5% ferrite. The invention also relates to a method of producing bands of said steel.
