I-Super duplex engagqwali njenge-duplex iyisakhiwo esincane esixubile se-austenite ne-ferrite esithuthukise amandla ngaphezu kwamabanga ensimbi ye-ferritic ne-austenitic.Umehluko omkhulu ukuthi i-super duplex inokuqukethwe okuphezulu kwe-molybdenum ne-chromium okunikeza impahla ukumelana nokugqwala okukhulu.I-Super duplex inezinzuzo ezifanayo nezakwabo - inezindleko eziphansi zokukhiqiza uma iqhathaniswa namabanga afanayo e-ferritic nawe-austenitic futhi ngenxa yezinto zokwakha ezikhuphukayo eziqinile namandla okukhiqiza , ezimweni eziningi lokhu kunikeza umthengi inketho eyamukelekayo yokuthenga ugqinsi oluncane ngaphandle kwesidingo sokuyekethisa kukhwalithi nokusebenza.

Izici :
1 .Okuvelele ukumelana nokugqwala nokugqwala emanzini olwandle nakwezinye izindawo ezine-chloride, nezinga lokushisa elibalulekile le-pitting elingaphezu kuka-50°C.
2 .I-ductility enhle kakhulu namandla womthelela kukho kokubili izinga lokushisa le-ambient ne-sub-zero
3 .Ukumelana okuphezulu nokuhuzuka, ukuguguleka nokuguguleka kwe-cavitation
4 .Ukumelana okuhle kakhulu nokuqhekeka kokugqwala kwengcindezi ezindaweni eziqukethe i-chloride
5 .Imvume ye-ASME yokusetshenziswa komkhumbi ocindezelayo
