摘要：The invention relates to a method for producing a highly resistant (at least900MPa), very ductile steel strip. The steel, containing (in mass per cent); 0.10 to 0.20 % C;0.30 to 0.60 % Si; 1.50 to 2.00 % Mn; max. 0.08 % P; 0.30 to 0.80 % Cr; up to 0.40 % Mo; upto 0.20 % Ti and/or Zr; up to 0.08 % Nb; the remainder being Fe and unavoidable
impurities, is melted, cast in slabs and then rolled out into a hot rolled strip. The roll endtemperature is above 800oC, the cooling speed on the delivery roller table is at least30oC/s and the reel temperature is 300 to 600oC.
