Embodiment Construction

[0044] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0045] The invention relates to an alloy steel with high strength and high wear resistance. The main composition is iron, and other elements except iron include carbon, manganese, molybdenum, nickel, copper, boron, titanium, magnesium and rare earth cerium, carbon The content is 0.35-0.50%.

[0046] Preferably, the weight percent range of each component of the alloy steel is: carbon 0.35-0.50%, manganese 0.25-0.30%, molybdenum 0.05-0.12%, nickel 1-5%, copper 0.05-0.12%, boron 0.04-0.08%, titanium 0.10-0.15%, magnesium 0.5-0.8%, rare earth cerium 0.01-0.03%, and the rest is iron.

[0047] The manganese content in the alloy steel of the present invention is relatively high, and when the manganese content is relatively high, manganese can replace iron or form alloy ceme...

Abstract

The invention provides alloy steel with high strength and high wear resistance. The alloy steel takes iron as a main, and further comprises other elements including carbon, manganese, molybdenum, nickel, copper, boron, titanium, magnesium and rare earth cerium, wherein the content of the carbon ranges from 0.35 to 0.50%. Preferably, the alloy comprises, by weight percent, 0.35 to 0.50% of carbon,0.25 to 0.30% of manganese, 0.05 to 0.12% of molybdenum, 1 to 5% of nickel, 0.05 to 0.12% of copper, 0.04 to 0.08% of boron, 0.10 to 0.15% of titanium, 0.5 to 0.89% of magnesium, 0.01 to 0.03% of rareearth cerium and the balance iron. The content of manganese in the alloy steel is higher, the manganese containing few impurities is hard and fragile, the manganese can enhance hardness of the iron,and cannot reduce ductility and toughness of the iron, and the strength of the alloy steel can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to an alloy steel with high strength and high wear resistance. Background technique [0002] In addition to iron and carbon, alloy steel is called alloy steel by adding other alloying elements. Adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel constitutes an iron-carbon alloy. 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. [0003] There are many types of alloy steel, usually divided into low alloy steel (content <5%), medium alloy steel (content 5% ~ 10%), high alloy steel (content >10%) according to the content of alloy elements; divided into high quality according to the quality Alloy steel,...
