The invention belongs to the technical field of wear-resistant materials, and particularly relates to a wear-resistant and corrosion-resistant liner plate and a preparation method thereof. The wear-resistant and corrosion-resistant liner plate is prepared from the following components in percentage by weight: 0.6-1% of carbon, 0.4-0.8% of silicon, 0.4-0.85% of magnesium, 0.4-1.0% of manganese, 9-13% of chromium, 1.5-1.9% of molybdenum, 0.1-0.22% of nickel, 0.05-0.20% of titanium, 0.005-0.04% of phosphorus, 0.005-0.04% of sulfur, and the balance of iron. A formula is reasonable, manufacturing is easy, the service life is long, quite high strength, toughness, wear resistance and impact resistance are achieved, the frequency of replacing the wear-resistant and corrosion-resistant liner platein a factory is reduced, the labor intensity is lowered, raw materials are easy to obtain, a manufacturing method is simple, and energy is effectively saved.
