The hardness of high manganese steel liners can be adjusted by different treatment processes, usually varying in the range of HB 180-800.
High manganese steel lining plate, as a wear-resistant material, its hardness can be increased by hardening treatment. Under impact load, the surface can produce a hardened layer, thus improving wear resistance. The specific hardness value depends on the type and degree of impact load sustained. Under low impact load, the hardness of high manganese steel liner can reach HB 300 ~ 400, while under high impact load, its hardness can be further increased to HB 500 ~ 800. In addition, the surface hardening layer of the high manganese steel liner can reach 10~20 mm depth, this high hardness hardening layer can resist the wear of the grinding medium.
The hardening of high manganese steel plate can be explosive hardening and peshot treatment process, through these treatments, the hardness of high manganese steel plate can be increased to 55 HRC, thus further improving its wear resistance. The machining hardening characteristic of this material makes it a very good choice as a wear-resistant protective liner in harsh working conditions.
In conclusion, the hardness of high manganese steel lining plate is an adjustable parameter, and the required hardness value can be achieved by appropriate hardening treatment to meet different working conditions and wear resistance requirements.
