Problems solved by technology

[0004] In short, the existing low-alloy wear-resistant steel does not make full use of the V / Mo synergy to improve hardenability, and the total addition of alloy elements is relatively high, so the steel cost is high and the weldability is poor

Abstract

The invention discloses low-alloy wear-resistant steel and a manufacturing method thereof. The low-alloy wear-resistant steel comprises the following components in percentage by weight: 0.13-0.50 percent of C, 0.10-0.50 percent of Si, 0.30-1.50 percent of Mn, 0.125-0.40 percent of V, 0.05-0.30 percent of Mo, less than 0.020 percent of P, less than 0.010 percent of S and the balance of Fe and inevitable impurities. The low-alloy wear-resistant steel has the advantages of low cost, series strength, excellent low-temperature toughness and low welding carbon equivalent weight, and can be widely applied to mechanical products with high requirements on strength and wear resistance in engineering, ore mining, buildings, cement production, ports, electric power, metallurgy and the like.

Description

technical field [0001] The invention relates to a wear-resistant steel, in particular to a V / Mo synergistic low-alloy wear-resistant steel and a manufacturing method thereof. Background technique [0002] Wear-resistant steel plates are widely used in mechanical products such as engineering, mining, construction, cement production, ports, electric power and metallurgy that require high strength and high wear resistance, such as bulldozers, loaders, excavators, dump trucks and various mining machinery , grab bucket, stacker reclaimer, feeding bending structure, etc. In order to improve hardenability and obtain a quenched martensitic structure with uniform structure and properties along the thickness direction of the steel plate, the existing wear-resistant plates generally adopt higher carbon content and alloy element content, especially containing more Mo, Ni, Cr Such precious alloying elements increase the production cost of the steel plate, deteriorate the welding perform...
