Abstract

The invention relates to a high-hardness and high-abrasion-resistance iron alloy material. The material comprises the following components by weight percent: 0.8-1.2% of carbon, 0.6-0.65% of silicon, 1.1-1.3% of manganese, 1.4-1.6% of chromium, 0.1-0.2% of molybdenum, 0.05-0.1% of nickel, 0.8-1.2% of aluminium, 0.3-0.5% of copper, 0.02-0.03% of titanium, 0.03-0.06% of vanadium, 0.0005-0.001% of cerium, 0.002-0.003% of boron, 0.03-0.05% of cobalt and the balance of iron and inevitable impurities. The material has the following beneficial effects that use of noble metals and rare earth is reduced; and high hardness and high abrasion resistance of the iron alloy are also achieved by adopting the elements with high contents and low prices instead of the noble metals and rare earth.

Description

technical field [0001] The invention belongs to the field of metal casting, and refers to a material for metal casting, in particular to a high hardness and high wear resistance ferroalloy material. Background technique [0002] In the field of machinery and other fields, in order to increase the processing speed and reduce the processing procedures, many parts are processed by casting, especially for some parts with complex structures, the process of machining is very complicated. Casting can be formed at one time and has been widely used. [0003] On the other hand, by adopting the casting processing method, the properties of the alloy can be adjusted according to the needs of the product to be processed, that is, certain properties of the alloy can be improved by changing the material composition in the alloy. In the casting process of the current technology, in order to improve or enhance a certain property in the alloy, it is generally achieved by adding elements that ...
