Problems solved by technology

[0004] It can be seen that in order to improve the wear resistance of high manganese steel, people have added more expensive and scarce alloy materials to high manganese steel. Although the performance of manganese steel has been improved, the cost has also increased significantly. It is also more complicated, and its price / performance ratio is not ideal

Abstract

The invention discloses a modified high manganese steel, which comprises the following parts: 1.1-1.4% C, 15-20% Mn, 0.5-1% Si, 0.3-2.5% Cr, 0.1-5% Re and Fe. The hardness of steel is improved by HV100-500 with higher impaction-proof and abrasion-proof property, which lengthens the lifetime by 2-4 times.

Description

technical field [0001] The invention relates to an alloy material, more specifically, relates to a high manganese steel material with high wear resistance. Background technique [0002] Manganese steel is a wear-resistant material with a long history. Its production technology has developed rapidly in recent years. Because of its high impact toughness and work hardening characteristics, it is still widely used in cement, metallurgy, mining, electric power, coal, etc. Products in grinding, crushing, loading, etc. [0003] Due to the unsatisfactory impact resistance and wear resistance of the original high manganese steel and alloy steel, the loss during use is relatively high. In order to further improve the impact resistance and wear resistance of high manganese steel, prolong its service life, and seek new steel types suitable for different working conditions, researchers from various countries have carried out research on the modification and realloying of high manganese ...
