Isingeniso
Izinsimbi ezingagqwali zingama-high-alloy steels.Lezi zinsimbi zitholakala ngamaqembu amane ahlanganisa i-martensitic, austenitic, ferritic kanye nezinsimbi eziqinile zemvula.Lawa maqembu akhiwa ngokusekelwe esakhiweni se-crystalline sezinsimbi ezingenasici.
Izinsimbi ezingenasici ziqukethe amanani amakhulu e-chromium uma ziqhathaniswa nezinye izinsimbi futhi ngaleyo ndlela zinokumelana nokugqwala okuhle.Iningi lezinsimbi ezingenasici liqukethe cishe u-10% we-chromium.
I-Grade 2205 insimbi engagqwali iyinsimbi engagqwali eyi-duplex umklamo wayo ovumela ukuhlanganisa ukumelana nomgodi, amandla aphezulu, ukugqwala kwengcindezi, ukugqwala kokuqhekeka kanye nokuqhekeka.Ibanga 2205 insimbi engagqwali imelana ne-sulfide stress corrosion kanye ne-chloride environment.
Iminingwane elandelayo inikezela ngesifinyezo sensimbi engagqwali yebanga 2205.
