When the high manganese steel casting is subjected to impact interception and compressive stress, the metal surface has plastic deformation, rapidly produces processing hardening and inducing the martensite and ε phase, thus forming a hard and wear-resistant surface layer, and the patient part is still the austenitic tissue. The hardness of the surface layer is increased from about 200 HB to more than 500 HB, and the concentration bilong hatening leit inap long kamap 10~20mm, o moa{{6} taim ples i bagarap isi isi, strong bilong en i wok long go insait isi isi, strong bilong hat i wok long go insait oltaim aninit long wok bilong impak lod{{7} long taim bilong liklik impak lod na liklik stres wear, wear resistens bilong hai manganese stiel i no gutpela moa long ol narapela kain steel kain strongpela hat long pes bilong pes i antap i no gat magnetik, tasol ol inap yusim tu long ol hap i no inap bagarap na magnetisasen i no inap bagarap, olsem ilektromagnet kava bilong sut bilong saksen divais.
