Abstract

Provided are a high-strength thin-gauge checkered steel plate/strip comprising the following chemical elements in weight percentages: C: ≤0.06%, Si: ≤0.5%, Mn: 0.4-1.7%, P≤0.04%, S≤0.007%, N: 0.004-0.010%, Als: <0.001%, B: 0.001-0.006%, Mn/S≥250, total oxygen [O]: 0.007-0.020%; Cu: 0.1-0.6% and/or Sn: 0.005-0.04%; and a balance of Fe and other unavoidable impurities, and a manufacturing method thereof. The resultant steel roll can be used directly as hot-rolled checkered plate/strip, or as a finished checkered plate/strip after being cut and finished, and is widely applicable to the fields of architecture, mechanical production, automobile, bridges, transportation, ship building, etc.
