Abstract

The invention discloses wear-resistant alloy steel and a preparation method thereof. The alloy steel, prepared by the steps of smelting waste iron, waste steel and alloy containing silicon, manganese, chromium and molybdenum by using an intermediate frequency furnace, sampling and adjusting, moulding by casting and performing heat treatment, comprises the following components in percentage by weight: 0.33 to 0.55 percent of carbon, 0.60 to 1.20 percent of silicon, 1.50 to 3.20 percent of manganese, less than 0.04 percent of phosphorus, less than 0.04 percent of sulfur, 5.60 to 8.30 percent of chromium, 0.20 to 0.30 percent of molybdenum, 0.05 to 0.80 percent of vanadium and the balance of iron. According to the alloy steel, the wear resistance is greatly improved and is 2 to 5 times of that of high-chromium cast iron and high-manganese steel, the brittleness is low and the relative production cost is low.

Description

technical field [0001] The invention relates to the technical field of alloy steel manufacture, in particular to a wear-resistant alloy steel which has strong wear resistance and low brittleness and is suitable for civil use and popularization and a preparation method thereof. Background technique [0002] Alloy steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements to ordinary carbon steel. According to the different elements added and appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties can be obtained. According to the content of alloy elements in steel, it can be divided into low alloy steel, medium alloy steel and high alloy steel. [0003] The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titaniu...
