Thank you for your question. High manganese steel hammer is possess of toughness, which can make the surface hardened under the heavily stressed hammering action. In fact, the hardening phenomenon of high manganese steel hammer is not obvious when impact stress applying in hammer isn’t big, so there is not hard crust layer on the superficial layer. The hammer often be damaged by lots of materials when it starts to work, and the heavily stressed impact also causes sunken pit. Just because of these two functions, it is easy to be worn for high manganese steel hammer, and the service life is reduced gradually. According to those reasons, you can improve the hardening degree of hammer surface in order to make the surface hardened quickly. This method helps service life twice or triple longer than before.
