Ibha Eyisicaba Yensimbi Engagqwali engu-440c
Incazelo emfushane:
Amabha Ayisicaba e-UNS S44000, Amabha Ayisicaba e-SS 440, Umhlinzeki, Umkhiqizi kanye Nomthumeli Wezitsha Ezensimbi Engagqwali engu-440 eShayina.
Izinsimbi ezingagqwali ziyizinsimbi ezine-alloy ephezulu ezinokumelana nokugqwala okuphezulu uma kuqhathaniswa nezinye izinsimbi ngenxa yokuba khona kwenani elikhulu le-chromium. Ngokusekelwe esakhiweni sazo sekristalu, zihlukaniswe ngezinhlobo ezintathu njengezinsimbi ze-ferritic, austenitic, kanye ne-martensitic. Elinye iqembu lezinsimbi ezingagqwali yizinsimbi eziqiniswe yimvula. Ziyinhlanganisela yezinsimbi ze-martensitic neze-austenitic. Insimbi engagqwali ye-Grade 440C iyinsimbi engagqwali ye-martensitic ene-carbon ephezulu. Inamandla aphezulu, ukumelana nokugqwala okumaphakathi, kanye nokuqina okuhle kanye nokumelana nokugqwala. I-Grade 440C iyakwazi ukuthola, ngemva kokwelashwa ngokushisa, amandla aphezulu, ubulukhuni kanye nokumelana nokugqwala kwazo zonke izinsimbi ezingagqwali. Okuqukethwe kwayo okuphezulu kakhulu kwekhabhoni kunesibopho salezi zici, okwenza i-440C ifaneleke kakhulu ekusetshenzisweni okufana nama-ball bearings kanye nezingxenye ze-valve.
