Abstract

The invention relates to the technical field of metal welding materials, in particular to an impact-resistant abrasion-resistant composite steel plate. The impact-resistant abrasion-resistant composite steel plate comprises a base plate layer and an abrasion-resistant layer, wherein the base plate layer is a common steel plate, and the abrasion-resistant layer is a high-strength alloy composite layer. The abrasion-resistant layer comprises, by weight, 25.00%-55.00% of chromium, 3.00%-8.00% of carbon, 0.50%-4.00% of manganese, 0.10%-3.00% of silicon, 0.25%-3.00% of nickel, 0.25%-3.00% of molybdenum, 0.10%-1.50% of vanadium, and the balance iron and inevitable impurities. The impact-resistant abrasion-resistant composite steel plate overcomes the defects that precious metal adding in a traditional abrasion-resistant layer is high and the abrasion resistance is low caused by low C content. By adding a small amount of vanadium with lower cost, the abrasion resistance of the abrasion-resistant layer is improved. According to the impact-resistant abrasion-resistant composite steel plate, the C content is increased within the range of components and proportions, but the abrasion-resistantlayer still has better toughness, so that the composite steel plate has better abrasion-resistant strength and toughness.

Description

technical field

[0001] The invention relates to the technical field of metal welding materials, in particular to an impact-resistant and wear-resistant composite steel plate. Background technique

[0002] The traditional double-metal composite wear-resistant steel plate is composed of low-carbon steel plate and alloy wear-resistant layer. The wear-resistant layer generally accounts for 1 / 3-1 / 2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity against external forces, and the wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions. Wear-resistant steel plate has high wear resistance and good impact performance, can be cut, bent, welded, etc., and can be connected with other structures by welding, plug welding, bolt connection, etc., which saves time and Convenient and other features, it is widely used in metallurgy, coal, cement, electric pow...
