摘要：
A bulletproof steel plate with a tensile strength of 2000 MPa grade and a Brinell Hardness of 600 grade and a manufacturing method thereof, characterized by that the chemical elements in mass percentage thereof being: 0.35-0.45% of C, 0.80-1.60% of Si, 0.3-1.0% of Mn, 0.02-0.06% of Al, 0.3-1.2% of Ni, 0.30-1.00% of Cr, 0.20-0.80% of Mo, 0.20-0.60% of Cu, 0.01-0.05% of Ti, 0.001-0.003% of B, and the balance being Fe and inevitable impurities. The tensile strength of the steel plate can reach a grade of 2000 MPa and its Brinell Hardness can reach a grade of 600.
