A low-alloy high-performance wear-resistant steel plate and a manufacturing method therefor, the steel plate having the following chemical composition (wt%): C: 0.21-0.32%; Si: 0.10-0.50%; Mn: 0.60-1.60%; 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%, such that 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 is Fe and unavoidable impurities. The above chemical composition and TMCP are used to obtain a wear-resistant steel plate that has a high degree of hardness, excellent resilience, and outstanding wear resistance, and that is thereby suitable for use in all manner of machine parts susceptible to wear and tear. |
