Uma kuqhathaniswa nepayipi lensimbi engagqwali ye-austenitic, ukushiyeka kwepayipi lensimbi engagqwali eliyi-duplex limi kanje:
I-1) i-universality yesicelo kanye ne-multi-faceted njengensimbi engagqwali ye-austenitic, isibonelo, izinga lokushisa lokusetshenziswa kwalo kufanele lilawulwe ku-250 degrees Celsius.
2) ukuqina kwayo kwepulasitiki kune-austenitic insimbi engagqwali ephansi, ebandayo, ubuchwepheshe bokucubungula okushisayo kanye nokwenza ukusebenza njengensimbi engagqwali ye-austenitic.
3) ubukhona bendawo yokushisa ephakathi nendawo, isidingo sokulawulwa okuqinile kokwelashwa kokushisa kanye nesistimu yenqubo yokushisela ukugwema ukuvela kwesigaba esiyingozi, ukusebenza komonakalo.
