Duplex ibyuma bidafite ibyuma bifite ibiranga ibyuma bya austenitis bitagira ibyuma na ferritic ibyuma bidafite ibyuma kuko bifite austenite + ferrite ibyiciro bibiri kandi ibikubiye mubyiciro byombi ni bimwe. Imbaraga z'umusaruro zishobora kugera kuri 400Mpa ~ 550MPa, zikubye kabiri icyuma gisanzwe cya austenitis. Ugereranije nicyuma cya ferritic, ibyuma bya duplex bidafite ibyuma bifite ubukana bwinshi, ubushyuhe buke bwinzibacyuho, byateye imbere cyane kurwanya ruswa hagati yimikorere no gusudira; mugihe hagumijwe ibintu bimwe na bimwe biranga ferritic idafite ibyuma, nka 475 itt ubwitonzi, ubushyuhe Umuyoboro mwinshi, coefficente ntoya yo kwagura umurongo, superplasticity na magnetique. Ugereranije nicyuma cya austenitike, ibyuma bya duplex bitagira ibyuma bifite imbaraga nyinshi, cyane cyane imbaraga zumusaruro zateye imbere cyane, kandi kurwanya ruswa, kurwanya ruswa, kurwanya umunaniro wa ruswa nibindi bintu nabyo byateye imbere kuburyo bugaragara.
Duplex ibyuma bidafite ibyuma bishyirwa mubwoko bune: Cr18, Cr23 (ukuyemo Mo), Cr22 na Cr25 ukurikije imiterere yabyo. Kubijyanye na Cr25 duplex idafite ibyuma, irashobora kugabanywamo ibyuma bisanzwe kandi super duplex ibyuma. Muri byo, Cr22 na Cr25 zikoreshwa cyane. Ibyinshi mu byuma bya duplex bitagira umuyonga bikoreshwa mu Bushinwa bikorerwa muri Suwede. Amanota yihariye ni: 3RE60 (ubwoko bwa Cr18), SAF2304 (ubwoko bwa Cr23), SAF2205 (ubwoko bwa Cr22), na SAF2507 (ubwoko bwa Cr25).
