A low alloy high toughness wear-resistant steel plate and manufacturing method thereof, the chemical composition (wt%) of the steel plate being: C: 0.08-0.20%; Si: 0.10-0.60%; Mn: 1.00-2.00%; B: 0.0005-0.0040%, Cr≤1.50%, Mo≤0.80%, Ni≤1.50%, Nb≤0.080%, V≤0.080%, Ti≤0.060%, Al: 0.010-0.080%, Ca: 0.0010-0.0080%, N≤0.0080%, O≤0.0080%, H≤0.0004%, P≤0.015%, S≤0.010%; and 0.20%≤（Cr/5+Mn/6+50B）≤0.55%, 0.02%≤（Mo/3+Ni/5+2Nb）≤0.45%, and 0.01%≤（Al+Ti）≤0.13%; and the balance being Fe and incidental impurities. By taking full advantage of the refining and reinforcement of microalloy elements such as Nb, Ti, and the like, and a TMCP process, the wear-resistant steel plate has high strength, good hardness and toughness, and excellent wear resistance, and is easy to weld, thus being suitable for any component taking wear in various kinds of mechanical equipment. |
