摘要（英）：

The present invention discloses a normalized A537CI1 steel plate for pressure vessels and a production method thereof, and belongs to the technical field of steel and iron production. The weight percentages of ingredients of said steel plate are: 0.17-0.24% of C, 0.15-0.50% of Si, 0.7-1.35% of Mn, P<=0.010%, S<=0.010%, Mo<=0.08%, 0.14-0.25% of Ni, Nb<=0.05%, and 0.020-0.050% of TA1, the balance being Fe and unavoidable impurities. The production method includes processes of smelting, heating, rolling and normalizing heat treatment. The steel plate provided by the invention is stable in mechanical property and excellent in internal soundness, the tensile strength R[m] of the steel plate is 485-620 Mpa, the yield strength R[p]0.2>=345 MPa, the ductility A[50]>=22%, and the ballistic work ata temperature of -20 DEG C is larger than 50 J, so the steel plate is completely applicable to production of pressure vessels.
