65Mn simbi ndiro, manganese inovandudza kuoma, φ 12mm simbi inogona kudzimwa zvakakwana mumafuta, uye maitiro ayo epamusoro decarburization idiki pane iyo yesilicon simbi.Iyo yakazara mechanical zvivakwa mushure mekupisa kurapwa zviri nani pane iyo kabhoni simbi, asi ine overheating senitivity uye tempering brittleness.Inogona zvakare kushandiswa kugadzira mhete dzechitubu, zvitubu zvevharuvhu, zvitubu zveclutch, zvitubu zvemabhureki uye simbi inotonhorera inodhonzwa waya inotonhora coil zvitubu.Kusimba, kuoma, elasticity uye kuomarara kwe65Mn simbi ndiro yakakwirira kupfuura iyo ye65 simbi.Iine katsika kekupisa kunzwisiswa uye kushatisa brittleness, uye kudzima kwemvura kune tsika yekuumba mitswe.Iyo machinability mune annealed state inogamuchirwa, iyo inotonhora deformation plasticity yakaderera, uye weldability yakashata.
