Ezweni lobunjiniyela obunembile, ukukhetha izinto zokwakha kuyikho konke. Kungakhathaliseki ukuthi kungokwezingxenye zezindiza, amagiya ezimoto, noma izingxenye zamathuluzi anokucindezeleka okukhulu, ukuthembeka kwezinto zokwakha kuchaza ukusebenza komkhiqizo. Phakathi kwezinsimbi ezahlukahlukene ze-alloy,Insimbi engu-4140isivele njengenye yezinto ezithembeke kakhulu zokusetshenziswa ngokunemba. Inhlanganisela yayo eyingqayizivele yamandla, ukuqina, kanye nokusebenza kahle kwemishini iyenza ibe yinto ebalulekile kwezobunjiniyela kanye nokukhiqiza.
Kulesi sihloko, i-sakysteel ihlola indima ebalulekile yensimbi engu-4140 ekusetshenzisweni okunembile, iqokomisa izakhiwo zayo, izinzuzo, kanye namacala okusetshenziswa kwayo kuzo zonke izimboni.
Iyini insimbi engu-4140?
Insimbi engu-4140 iyi-insimbi ye-chromium-molybdenum engxubevange ephansienikeza izakhiwo ezinhle kakhulu zemishini. Ingokwesistimu yokulinganisa insimbi ye-AISI-SAE futhi ihlukaniswe njengengxube yobunjiniyela esetshenziselwa izingxenye ezibhekene nokucindezeleka okukhulu kwemishini.
Ukwakheka kwamakhemikhali ayo kuhlanganisa:
-
Ikhabhoni:0.38–0.43%
