Duplex bakin karfe yana da halaye na austenitic bakin karfe da ferritic bakin karfe saboda yana da austenite + ferrite dual lokaci tsarin da abun ciki na biyu lokaci Tsarin ne m iri daya. Ƙarfin yawan amfanin ƙasa zai iya kaiwa 400Mpa ~ 550MPa, wanda shine sau biyu na talakawa austenitic bakin karfe. Idan aka kwatanta da ferritic bakin karfe, duplex bakin karfe yana da high tauri, low gaggautsa zafin jiki, muhimmanci inganta intergranular lalata juriya da waldi yi; yayin da yake riƙe da wasu halaye na bakin karfe na ferritic, irin su 475 ℃ brittleness, zafi High conductivity, kananan mikakke fadada coefficient, superplasticity da Magnetic Properties. Idan aka kwatanta da austenitic bakin karfe, duplex bakin karfe yana da mafi girma ƙarfi, musamman yawan amfanin ƙasa ƙarfi ne sosai inganta, da pitting lalata juriya, danniya lalata juriya, lalata gajiya juriya da sauran kaddarorin kuma sun inganta sosai.
Bakin Karfe Duplex an rarraba su zuwa nau'i hudu: Cr18, Cr23 (ban da Mo), Cr22 da Cr25 bisa tsarin sinadaran su. Amma ga Cr25 duplex bakin karfe, shi za a iya raba talakawa da kuma super duplex bakin karfe. Daga cikin su, Cr22 da Cr25 an fi amfani da su. Yawancin bakin karfen duplex da ake amfani da su a kasar Sin ana kera su ne a kasar Sweden. Takaitattun maki sune: 3RE60 (nau'in Cr18), SAF2304 (nau'in Cr23), SAF2205 (nau'in Cr22), da SAF2507 (nau'in Cr25).
