前言高锰钢问世到现在已有100年的历史,由于该钢具有较高力学性能及在重力冲击和挤压条件下引起铸件表面加工硬化,因而具有高抗磨性能,故在冶金、矿山机械、履带式拖拉机和坦克等方面得到了很广泛的应用。近年国内外尽管开展了代用锰钢的研究,但由于历史原因或锰资源的富有,故高锰钢铸件的生产量仍十分可观,因此高锰钢质量控制是不容忽视的实际问题。一、化学成份: 1.碳: 碳是该钢中基本元素之一,它能强化固溶
Preface High manganese steel come out to now has 100 years of history, due to the high mechanical properties of the steel and caused by gravity impact and extrusion conditions caused by work hardening of the casting surface, which has high wear resistance, it is in the metallurgy, mining machinery , Crawler tractors and tanks has been very widely used. In recent years, despite the development of alternative manganese steel at home and abroad, due to historical reasons or the richness of manganese resources, the production of high manganese steel castings is still considerable. Therefore, the quality control of high manganese steel is an actual problem that can not be ignored. First, the chemical composition: 1. Carbon: Carbon is one of the basic elements of the steel, it can strengthen the solution
