Abstract (en)
[origin: WO2007024092A1] A hot rolled steel sheet used for a bumper reinforcing material or for an impact absorption material in a door of automobiles, and a method for manufacturing the same are disclosed. The steel sheet comprises, by weight%, C: 0.2% ~ 1%, Mn: 8 ~ 15%, S: 0.05% or less, P: 0.03% or less, and the balance of Fe and other unavoidable impurities. A product of tensile strength and total elongation (TS x ToLEl) of the steel sheet is 24,000 MPa% or more. The method provides a high strength hot rolled steel sheet, which has a high strength-elongation balance value, ensuring excellent workability.
