Isingeniso
Izinsimbi ezingagqwali ziyizinsimbi ezine-alloy ephezulu. Lezi zinsimbi zitholakala ngamaqembu amane ahlanganisa izinsimbi ze-martensitic, i-austenitic, i-ferritic kanye nezinsimbi eziqiniswe yimvula. La maqembu akhiwa ngokusekelwe esakhiweni sekristalu sezinsimbi ezingagqwali.
Izinsimbi ezingagqwali ziqukethe inani elikhulu le-chromium uma kuqhathaniswa nezinye izinsimbi ngakho-ke zinokumelana okuhle nokugqwala. Iningi lezinsimbi ezingagqwali liqukethe cishe u-10% we-chromium.
Insimbi engagqwali yebanga 2205 iyinsimbi engagqwali ephindwe kabili eklanywe ngayo eyenza kube lula ukuhlanganisa ukumelana okuthuthukisiwe nokuqhekeka, amandla aphezulu, ukugqwala kokucindezeleka, ukugqwala kwemisele kanye nokuqhekeka. Insimbi engagqwali yebanga 2205 imelana nokugqwala kokucindezeleka kwe-sulfide kanye nezindawo ze-chloride.
Ishidi ledatha elilandelayo linikeza umbono jikelele wensimbi engagqwali yebanga lika-2205.
