Cu-containing austenite high-manganese wear-resistant steel bucket tooth and manufacturing method thereof
The invention belongs to the technical field of wear-resistant steel, and particularly relates to a Cu-containing austenite high-manganese wear-resistant steel bucket tooth and a manufacturing method thereof.The Cu-containing austenite high-manganese wear-resistant steel bucket tooth is prepared from, by mass, 1.1%-1.3% of C, 12.4%-12.6% of Mn, 0.4%-0.6% of Si, 1.7%-1.9% of Cr, 0.2%-0.4% of Mo, 0.4%-0.5% of Ni, 0.06%-0.08% of Al, 0.3%-0.5% of Cu, smaller than or equal to 0.01% of S, smaller than or equal to 0.02% of P and the balance Fe and inevitable impurity elements; traditional high manganese steel is subjected to microalloying treatment, Cu, Al, Ni and other elements are added, an improved casting process and an improved heat treatment process are matched, the hardness, impact toughness and wear resistance are excellent, the structure of the prepared Cu-containing austenite high-manganese wear-resistant steel bucket tooth comprises austenite and precipitates, the service life is long, and the service life is long. And the wear resistance is obviously improved compared with the traditional wear-resistant high-manganese steel.
本发明属于耐磨钢技术领域，具体为一种含Cu奥氏体高锰耐磨钢斗齿及其制造方法，所述含Cu奥氏体高锰耐磨钢斗齿，以质量百分比计，其组成包括，C：1.1～1.3％、Mn：12.4～12.6％、Si：0.4～0.6％、Cr：1.7～1.9％、Mo：0.2～0.4％、Ni：0.4～0.5％、Al：0.06～0.08％、Cu：0.3～0.5％、S≤0.01％、P≤0.02％，其余为Fe和不可避免的杂质元素；本发明对传统高锰钢进行微合金化处理，加入Cu、Al、Ni等元素，且匹配改进的铸造工艺和热处理工艺，硬度、冲击韧性及耐磨性能优良，制备的含Cu奥氏体高锰耐磨钢斗齿的组织包括奥氏体和析出物，其使用寿命长，耐磨性能较传统耐磨高锰钢有明显提升。
