Simbi inonzi duplex stainless steel mu ferrite phase yayo yakasimba uye austenite inosangana nehafu yega yega, kazhinji huwandu hushoma hwehuwandu hunofanirawo kusvika 30%. Kana iri C yakaderera, Cr iri pakati pe18% kusvika 28%, Ni iri pakati pe3% kusvika 10%. Imwe simbi ine Mo, Cu, Nb, Ti, N nezvimwe zvinhu zve alloying.
Zvakanakira.
Simbi iyi ine hunhu hwesimbi isina ngura inonzi austenitic neferritic,
1. Kuenzanisa neferrite, plasticity, kuomarara kwakanyanya, kushaya simba kwekushisa kwemumba, kuramba ngura pakati pegranular uye kushanda kwewelding zvinovandudzika zvakanyanya, ukuwo zvichichengetedza simbi. Simbi isina tsvina yakakwana 475 ℃ brittleness uye high thermal conductivity, ine superplasticity nezvimwewo.
2. Kana tichienzanisa nesimbi isingasvibiswi inonzi austenitic, simba rayo guru uye kuramba ngura pakati pegranular uye kuramba ngura ye chloride stress kwavandudzika zvakanyanya.
3. Simbi isina ngura mbiri inogona kuramba ngura zvakanaka, asiwo ine chikamu chesimbi isina ngura ye nickel.
