Igwe anaghị agba nchara nke Super duplex dị ka duplex bụ microstructure agwakọta nke austenite na ferrite nke megoro ike karịa ọkwa nchara ferritic na austenitic.Isi ihe dị iche bụ super duplex nwere molybdenum dị elu yana ọdịnaya chromium nke na-enye ihe ahụ nguzogide corrosion ka ukwuu.Super duplex nwere otu uru dị ka onye nke ya - ọ nwere ọnụ ahịa mmepụta dị ala ma e jiri ya tụnyere ụdị ferritic na austenitic na n'ihi ihe ndị ahụ na-abawanye tensile na ike na-amịpụta, n'ọtụtụ ọnọdụ nke a na-enye onye zụrụ ya nhọrọ nke ịzụrụ obere ọkpụrụkpụ na-enweghị mkpa imebi àgwà na arụmọrụ.

Atụmatụ:
1 .Mgbochi pụtara ìhè na olulu mmiri na corrosion crevice n'ime mmiri osimiri na chloride ndị ọzọ nwere gburugburu, yana oke ikpo ọkụ karịrị 50ºC.
2 .Ọkachamma ductility na ike mmetụta na ma ambient na obere okpomọkụ
3 .Nnukwu iguzogide abrasion, ozize na cavitation ozize
4 .Nguzogide dị oke mma maka mgbawa corrosion nrụgide na gburugburu chloride nwere
5 .Nkwado ASME maka ngwa arịa nrụgide
