Is the high manganese steel frog cast or rolled?

After casting or forging. According to the relevant published data, high manganese steel has high hardness and brittleness, and the rolling and pouring processes easily lead to the fracture and cracking of the material, thus reducing the performance and service life of the material. In contrast, casting and forging can improve the density and uniformity of materials, and at the same time adjust the organizational structure of materials, thus improving the strength and wear resistance of frog.
