Yaziwa ngamandla ayo angavamile, ukumelana okuphezulu nokugqwala, kanye nokwenza kalula imishini, iwumsebenzi oguquguqukayo ofanele izimboni ezihlukahlukene. Kulesi sihloko, sizohlola izici, izinhlelo zokusebenza, kanye nezinzuzo zensimbi engagqwali engu-17-4, kuhlanganise nokuthi kungani kuyisinqumo esikhethwayo ezimbonini eziningi.
Iyini i-17-4 Stainless Steel?
17-4 insimbi engagqwaliiyingxubevange yensimbi engagqwali ye-martensitic equkethe i-chromium engu-15-17% kanye ne-nickel engu-3-5%. Ibhalansi yakhiwe ngokuyinhloko ngensimbi, nezinye izakhi ezifana nethusi, i-molybdenum, ne-niobium yengezwe ukuze kuthuthukiswe izici zayo. Iyaziwa ngamandla ayo aphezulu, ukuqina, kanye nokumelana nokugqwala ezindaweni ezihlukahlukene.
Igama elithi “17-4″ libhekisela ekwakhiweni kwayo, ene-chromium engu-17% kanye ne-nickel engu-4%, enikeza insimbi izici zayo ezihlukile. Ngaphezu kwalokho, incazelo ye-AMS 5643, AISI 630, kanye ne-UNS S17400 zonke zibhekisela kwinto efanayo, ihlinzeka ngokungaguquguquki kuwo wonke amazinga ahlukahlukene asetshenziswa onjiniyela emhlabeni wonke.
Izakhiwo ezibalulekile ze-17-4 Stainless Steel
1. Amandla Aphezulu Nokuqina
Esinye sezici ezivelele ze-17-4 insimbi engagqwali amandla ayo. Ngenqubo yokwelapha ukushisa ebizwa ngokuthi ukuqiniswa kwemvula, le alloy ifinyelela amandla amangalisayo okubamba ukushisa, iyenze ifanelekele izinhlelo zokusebenza ezisebenza kahle kakhulu. Uma iqinisiwe, insimbi engagqwali engu-17-4 ingafinyelela amandla okukhiqiza afika ku-130 KSI (896 MPa) namandla aqinile we-160 KSI (1100 MPa).
2. Ukumelana Nokugqwala Okuhle Kakhulu
Ngenxa yokuqukethwe kwayo okuphezulu kwe-chromium,17-4 insimbi engagqwaliinokumelana okuhle kakhulu nokugqwala, ikakhulukazi ezindaweni ezigqwalile kancane.
