Abstract

The invention discloses a low-chrome wear-resistant alloy steel, and a preparation method thereof. The preparation method comprises following steps: technology target value determination, material preparation, melting, sampling and adjusting, casting and moulding, and hot treatment. The low-chrome wear-resistant alloy steel comprises, by weight, 0.25 to 0.35% of carbon, 0.6 to 1.5% of silicon, 0.8to 1.3% of manganese, phosphor<0.04%, sulfur<0.04%, 1 to 3.5% of chromium, 0.1 to 0.5% of nickel, 0.1 to 0.3% of molybdenum, 0.03 to 0.25% of boron, 0.1 to 0.3% of aluminium, 0.1 to 1.2% of cerium, 0.02 to 0.1% of tin, and the balance iron. According to the preparation method, both wear resistance and hardness requirements are satisfied, the toughness is increased greatly, impact resistance is excellent, impact energy is as high as 5 to 8 joules, and cobblestones can be crushed using the low-chrome wear-resistant alloy steel easily.

Description

technical field [0001] The invention relates to the technical field of alloy steel manufacture, in particular to a low-chromium wear-resistant alloy steel with impact resistance, high toughness and 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. The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, z...
