17-4PH 630 Ibha Yensimbi Engagqwali
Incazelo emfushane:
I-Saky Steel's 17-4PH / 630 / 1.4542 ingenye yezinsimbi ezingenasici ze-chromium-nickel alloy ethandwa kakhulu futhi evame ukusetshenziswa kakhulu enesengezo sethusi, imvula eqiniswe ngesakhiwo se-martensitic.Ibonakala ngokumelana nokugqwala okuphezulu ngenkathi igcina izakhiwo zamandla aphezulu, kufaka phakathi ubulukhuni.Insimbi ingasebenza ebangeni lokushisa ukusuka -29 ℃ kuya ku-343 ℃, kuyilapho igcina amapharamitha amahle kakhulu.Ngaphezu kwalokho, izinto ezikuleli banga zibonakala nge-ductility enhle futhi ukumelana nokugqwala kwazo kuqhathaniswa ne-1.4301 / X5CrNi18-10.
I-17-4PH, eyaziwa nangokuthi i-UNS S17400, iyinsimbi engagqwali eqinile enemvula ye-martensitic.Kuyinto eguquguqukayo futhi esetshenziswa kabanzi ezimbonini ezahlukahlukene, njenge-aerospace, nuclear, petrochemical, kanye nokucubungula ukudla.
I-17-4PH inamandla aphezulu, ukumelana nokugqwala okuhle, nobulukhuni obuhle uma kuqhathaniswa nezinye izinsimbi ezingenasici.Ingxube ye-chromium engu-17%, i-nickel engu-4%, ithusi engu-4%, nenani elincane le-molybdenum ne-niobium.Ukuhlanganiswa kwalezi zakhi kunikeza insimbi izici zayo eziyingqayizivele.
Sekukonke, i-17-4PH iwumsebenzi oguquguqukayo kakhulu futhi owusizo onikeza ibhalansi enhle yezakhiwo kuhlelo olubanzi lwezinhlelo zokusebenza.

| Ukwelashwa Kokushisa: |
Ukwelashwa kwesixazululo (Isimo A) — Izinsimbi ezingenasici zeBanga 630 zishisisa ku-1040°C amahora angu-0.5, bese zipholiswa ngomoya zibe ngu-30°C.Izingxenye ezincane zala mabanga zingacinywa ngamafutha.
Ukuqina - Izinsimbi ezingenasici zeBanga 630 ziqiniswa ngobudala emazingeni okushisa aphansi ukuze kuzuzwe izakhiwo ezidingekayo.Phakathi nenqubo, ukushintsha kombala okukha phezulu kwenzeka kulandelwa ukushwabana ku-0.10% esimweni H1150, kanye no-0.05% esimweni H900.
