65Mn inopisa yakakungurutswa simbi yakatenderedzwa mbariro

65Mn simbi iChinese GB yakajairwa chitubu giredhi, Manganese (Mn) inovandudza kuomarara, saka kusimba, kuomarara, kusimba uye kuoma kwakakwira kupfuura iyo ye65# simbi, asi ine overheat senitivity uye hasha brittleness. Kudzima kwemvura kunowanzoita mitswe. Iyo annealed state ine yakanaka machinability, yakaderera inotonhora deformation plasticity, uye kushomeka weldability.
65Mn high carbon steel inonyanya kushandiswa mukugadzira zvakasiyana-siyana zviduku-chikamu flat springs, zvitubu zvakatenderera, clockwork, nezvimwewo. Inogonawo kushandiswa kugadzira zvindori zvechitubu, zvitubu zvevhavha, zviputi zvekuvhundutsa, tsanga dzeclutch uye zvitubu zvekuputika.

Kuumbwa Kwemakemikari

Tafura iri pazasi inonyora 65Mn yakakwira kabhoni simbi kemikari yakagadzirwa zvichienderana nekupisa kwekuongorora.
