Ndeupi Musiyano Uripo Pakati pe17-4PH Nedzimwe Nsimbi Dzinosimbisa Mvura (PH)?

Nhanganyaya

Simbi dzisina kusimba dzinoomesa mvura (PH steels) imhando yesimbi dzisingapindi ngura dzinosanganisa simba resimbi dzemartensitic neaustenitic dzine simba rekudzivirira ngura. Pakati padzo,Simbi isina ngura ye17-4PHZvinofungidzirwa kuti ndiyo inonyanya kushandiswa nekuda kwehunhu hwayo hwemakanika uye nyore kugadzira. Asi inoenzaniswa sei nedzimwe mhando dzePH dzakadai se15-5PH, 13-8Mo, 17-7PH, uye Custom 465? Chinyorwa chino chinoongorora musiyano uripo mukugadzirwa, kurapwa kwekupisa, hunhu hwemakanika, kuramba ngura, uye mashandisirwo azvo.

Pfupiso yeNsimbi Dzisina Kuoma Dzemvura Dzinonaya

Simbi dzinoomesa mvura dzinowana simba radzo kubva pakuumbwa kwesimbi dzakapfava dziri musimbi panguva yekurapwa kwekupisa. Simbi idzi dzakakamurwa kuita mapoka matatu makuru:

1. Simbi dzeMartensitic PH(semuenzaniso,17-4PH, 15-5PH)
2. Simbi dzePH dzakaita seSemi-austenitic(semuenzaniso, 17-7PH)
3. Simbi dzeAustenitic PH(semuenzaniso, A286)
