Ishicilelwe ngu-sakysteel | Idethi: Juni 19, 2025

Isingeniso

Esimeni sezimboni zanamuhla,insimbi engagqwaliisibe ngenye yezinto ezibalulekile emikhakheni kusukela kwezokwakha namandla kuya ekunakekelweni kwezempilo kanye nasezimpahleni zasendlini. Yaziwa ngokumelana nokugqwala, amandla aphezulu, nokukhanga kobuhle, insimbi engagqwali iyaqhubeka nokulolonga umhlaba wesimanje.

Lesi sihloko sihlola umlando, izinhlobo, izinhlelo zokusebenza, izinzuzo, namathrendi esikhathi esizayo ensimbi engagqwali — enikeza ukuqonda kokuthi kungani ihlala iyinto ekhethwayo kuzo zonke izimboni zomhlaba. Kungakhathaliseki ukuthi ungumkhiqizi, unjiniyela, noma umtshali-zimali, ukuqonda inani lensimbi engagqwali kunganikeza umkhawulo wokuncintisana emakethe eguquguqukayo.

Iyini Insimbi Engagqwali?

Insimbi engagqwaliiwuhlobo lwengxubevange eyenziwe ngokuyinhloko ngensimbi ne-chromium, okungenani10.5% chromium ngobuningi. Ukuba khona kwe-chromium kwakha aungqimba lwe-chromium oxidengaphezulu, okuvimbela ukugqwala okwengeziwe futhi kuvimbele ukugqwala ukuthi kungasakazeki esakhiweni sangaphakathi sensimbi.

Kuye ngesicelo esihlosiwe, insimbi engagqwali ingase ihlanganise nezinye izakhi ezifanai-nickel, i-molybdenum, i-titanium, ne-nitrogen, okuthuthukisa izakhiwo zayo zemishini namakhemikhali.

Ukuvela Kwensimbi Engagqwali

Ukusungulwa kwensimbi engagqwali kudala emuva1913, lapho i-metallurgist yaseBrithaniUHarry Brearleywathola ingxubevange yensimbi ekwazi ukumelana nokugqwala ngenkathi ihlola imiphongolo yezibhamu. Lokhu kwaziswa okuguquguqukayo kwavula umnyango wezinhlelo zokusebenza ezimelana nokubola ezimpini, ezobunjiniyela, nasezimpahleni zabathengi.

Ngokuhamba kweminyaka, ukuthuthuka kwezobuchwepheshe kanye nokuqanjwa kabusha kwe-alloy kuye kwaholela ekuthuthukisweni kweamabanga angaphezu kwe-150yensimbi engagqwali, ngeimindeni emihlanu emikhulu: i-austenitic, i-ferritic, i-martensitic, i-duplex, kanye nokuqina kwemvula.
