I le duplex stainless steel (DSS), o le austenite vaega ma le ferrite vaega tala mo le tusa ma le afa o le fausaga vaifofo mautu, ma e lua-vaega fausaga uiga.E le gata ina taofia uiga o ferritic uamea uʻamea, e pei o le tele conductivity vevela, laʻititi laina faʻalauteleina coefficient, tetee i pitting corrosion ma crevice corrosion, ma chloride stress corrosion, ae e iai foi le malosi, maualalo brittle suiga vevela ma tetee i intergranular corrosion. o austenitic uamea uamea.Faʻatasi ai ma faʻatinoga lelei ma isi faʻamanuiaga, e faʻaaogaina lautele i petrochemical, lomitusi ma vali, inisinia o le gataifale, alamanuia meaʻai ma pisinisi fai pepa.
Faatasi ai ma le tulaga o le faateleina o le tele o meafaigaluega tau alamanuia faʻaonaponei ma faʻaititia le tau o gaosiga, o nisi o vaega tetele e tele lava ina gaosia e ala i le faʻapipiʻiina o le duplex stainless steel layers corrosion-resistant i luga o substrates uʻamea maualalo.
Strip electroslag surface process e fa'aaogaina lautele i le gaosiga ona o lona tulaga lelei uelo mautu, tulaga maualuga o masini, ma maualuga le gaosiga lelei.
