Ukukhiqiza:
Insimbi ebizwa nge-duplex stainless steel kusixazululo sayo esiqinile sesigaba se-ferrite kanye ne-austenite ihlangana nengxenye ngayinye, ngokuvamile okuqukethwe okuncane kokuqukethwe nakho kuyadingeka ukuthi kufinyelele ku-30%.Esimeni se-C ephansi, okuqukethwe kwe-Cr kuka-18% kuya ku-28%, okuqukethwe kwe-Ni kuka-3% kuya ku-10%.Enye insimbi iqukethe i-Mo, Cu, Nb, Ti, N nezinye izakhi ze-alloying.
Izinzuzo.
Insimbi inezici zensimbi engagqwali ye-austenitic ne-ferritic,
1. uma kuqhathaniswa ne-ferrite, i-plasticity, ukuqina okuphezulu, akukho ukushisa kwegumbi, ukumelana nokugqwala kwe-intergranular nokusebenza kwe-welding kuthuthukiswa kakhulu, kuyilapho i-mainta ining iron Insimbi engagqwali efanelekayo engu-475 ℃ i-brittleness kanye ne-conductivity ephezulu yokushisa, ne-superplasticity nokunye.
2. Ukuqhathanisa ne-austenitic insimbi engagqwali, amandla aphezulu kanye nokumelana nokugqwala kwe-intergranular kanye nokumelana nokugqwala kokucindezeleka kwe-chloride kuye kwathuthuka kakhulu.
3. Insimbi engagqwali e-Duplex inokumelana okuhle kakhulu nokumelana nokugqwala kwe-pitting, kodwa futhi nengxenye yensimbi engagqwali ye-nickel.
