高锰钢(1.20％碳、12.0％锰)是著名的特种钢之一,它被应用在需要有高硬度、抗磨,和冲击作用的机件上。从它的铸造性和金属学的观点上来说,是很少被人研究的。因为容易发生裂纹和其他缺陷,在铸造时就造成了很多的废品。文献上的材料载有当冲击载荷不大时,在它耐磨性的基础上,各种元素对它的影响。下面特别说明了钢的各种材料(参考书1至5)。确定锰钢的平均成份:1.2％碳、12.0 ％锰、小于1.0％矽、小于0.1％磷。在铸造厚铸件时,锰的含量大约是十倍于碳,
High manganese steel (1.20% carbon, 12.0% manganese) is one of the famous specialty steels and is used on parts that require high hardness, wear resistance, and impact. It has rarely been studied in terms of its castability and metallurgy. Because of cracks and other defects, casting creates a lot of scrap. The literature contains the impact of various elements on the basis of its wear resistance when the impact load is not large. The following describes the various materials of steel (References 1 to 5). Determine the average composition of manganese steel: 1.2% carbon, 12.0% manganese, less than 1.0% silicon, less than 0.1% phosphorus. When casting thick castings, the manganese content is about ten times that of carbon,
