Alloyed high manganese steel frog and manufacturing process thereof
The invention discloses an alloyed high manganese steel frog and a manufacturing process thereof. The chemical compositions (wt%) of the alloyed high manganese steel frog are as follows: the C contentis 0.95 to 1.35, the Mn content is 11.0 to 14.0, the Cr content is 0.2 to 1.0, the Mo content is 0. 2 to 1.2, the V content is 0.05 to 0.35, the Si content is 0.3 to 0.8, the Ni content is 0.002 to 1.5, the Re content is 0.001 to 0.05, the Mg content is 0.001 to 0.005, the P content is less than or equal to 0.045, the S content is less than or equal to 0.03, and the balance is Fe. In the alloyedhigh manganese steel frog prepared by the invention, the crystal grain size is 1 to 2 grades finer than that of an ordinary high manganese steel frog, which can improve the toughness of the high manganese steel frog, reduce the crack growth rate and increase the service life.
本发明公开了一种合金化高锰钢辙叉及其制造工艺，该辙叉的化学组成(wt％)为：C：0.95～1.35、Mn：11.0～14.0、Cr：0.2～1.0、Mo：0.2～1.2、V：0.05～0.35、Si：0.3～0.8、Ni：0.002～1.5、Re：0.001～0.05、Mg：0.001～0.005、P：≦0.045、S：≦0.03，其余为Fe。本发明制备的合金化高锰钢辙叉，晶粒尺寸比普通高锰钢辙叉细化1～2级，可提高高锰钢辙叉韧性，减小裂纹扩展速率，提高使用寿命。
