Mn15Cr1高锰无磁耐磨钢性能特点

所属分类:行业动态 发布时间:2021-05-26 来源:https://www.lcnaimoban.com/ 浏览量:

Mn15Cr1是高锰无磁耐磨钢,Mnl5Cr1和Mnl8Cr2超高锰钢是在Mnl3的基础上进一步提高碳、锰的含量,同时又加入了铬元素制成的。
Mn15cr1 is a high manganese non magnetic wear-resistant steel. Mnl5cr1 and mnl8cr2 ultrahigh manganese steel are made on the basis of Mnl3 to further improve the content of carbon and manganese, and at the same time, chromium is added to the steel.
增加碳含量可以提高合金的耐磨性,增加锰含量可以提高合金的固溶度,提高超高锰钢的冲击韧性。
The increase of carbon content can improve the wear resistance of the alloy, increase the manganese content can improve the solid solubility of the alloy and improve the impact toughness of the ultrahigh manganese steel.
高锰钢加入铬元素后,形成铬合金渗碳体(Fe,Cr)3C,比渗碳体Fe3C稳定,该合金渗碳体分布在钢中,使高韧性的奥氏体基体中分布着弥散碳化物硬质点,从而提高硬化效果,强化耐磨性。
After adding chromium element to high manganese steel, the cementite (Fe, Cr) 3C of chromium alloy is formed, which is more stable than that of Fe3C. The cementite of this alloy is distributed in steel, which makes the hard point of dispersed carbide distributed in the high toughness austenite matrix, thus improving the hardening effect and strengthening the wear resistance.
NM500耐磨板
适当提高碳、锰、铬含量后,经水韧处理后的超高锰钢比常规高锰钢的初始硬度高,加工硬化率也明显增加。
After the content of carbon, manganese and chromium is properly increased, the initial hardness of uhmn steel after water toughening treatment is higher than that of conventional high manganese steel, and the hardening rate of the steel is also increased obviously.
