摘要（英）：

The invention discloses a high-plasticity and high-tenacity thick steel plate and a production method thereof. The steel plate includes, by weight percentage, 0.04-0.09% of C, 0.10-0.40% of Si, 1.20-1.65% of Mn, 0.01-0.03% of Nb, 0.005-0.02% of Ti, not more than 0.06% of V, not more than 0.6% of Ni, not more than 0.3% of Cu, not more than 0.3% of Cr, not more than 0.010% of P, not more than 0.005% of S and the balance Fe and inevitable impurities. The production process includes the heating process, the rolling process and the cooling process. The produced steel plate is high in plasticity and tenacity. The elongation is larger than or equal to 26%. The Charpy impact energy of the steel plate at the temperature of -40 DEG C is larger than or equal to 300 J. The Charpy impact energy of the steel plate at the temperature of -60 DEG C is larger than or equal to 200 J. The Charpy impact energy of the steel plate at the temperature of -70 DEG C is larger than or equal to 100 J.
