Ibintu rusange
Alloy 2205 duplex idafite ibyuma ni Chromium 22%, Molybdenum 3%, 5-6% Nickel azote ivanze na duplex idafite ibyuma byerekana ibyuma rusange, byegereye kandi bihangayikishijwe no kwangirika kwangirika hiyongereyeho imbaraga nyinshi hamwe ningaruka zikomeye.
2205 ibyuma bidafite ingese
Alloy 2205 icyuma cya duplex kitagira ibyuma gitanga icyuma na crevice birwanya ruswa iruta 316L cyangwa 317L ibyuma bya austenitike bitagira ibyuma mubitangazamakuru hafi ya byose byangirika.Ifite kandi ruswa nyinshi hamwe nisuri yumunaniro hamwe no kwaguka kwinshi kwumuriro hamwe nubushyuhe bukabije bwumuriro kuruta austenitike.
Imbaraga zo gutanga umusaruro zikubye kabiri iz'icyuma cya austenitis.Ibi bituma umushushanya azigama ibiro kandi bigatuma amavuta arushanwe mugihe ugereranije na 316L cyangwa 317L.
2205 ibyuma bidafite ingese
Alloy 2205 duplex idafite isahani yicyuma irakwiriye cyane cyane kubisabwa bitwikiriye -50 ° F / + 600 ° F.Ubushyuhe hanze yuru rwego bushobora gutekerezwa ariko bukeneye kubuzwa, cyane cyane kububiko.
Kurwanya ruswa
Ruswa Rusange
Kubera chromium nyinshi (22%), molybdenum (3%), hamwe na azote (0.18%), ibintu birwanya ruswa byangiza 2205 duplex idafite ibyuma biruta iby 316L cyangwa 317L mubidukikije byinshi.
Kurwanya Ruswa
Chromium, molybdenum, na azote muri 2205 duplex idafite icyuma nacyo gitanga imbaraga nziza zo kwangirika no kwangirika ndetse no mubisubizo bya okiside na acide.
Isocorrosion Imirongo 4 mpy (0.1 mm / yr), mumuti wa acide sulfurike urimo 2000 ppm
Shimangira Kurwanya Ruswa
Duplex microstructure izwiho kunoza imitekerereze ya ruswa yangirika ibyuma bitagira umwanda.
Chloride ihangayikishijwe no kwangirika kwicyuma cya austenitis gishobora kutabaho mugihe ibintu nkenerwa byubushyuhe, guhangayika cyane, ogisijeni, na chloride bihari.Kubera ko ibi bintu bitagenzurwa byoroshye, gucika intege kwangirika byakunze kuba inzitizi yo gukoresha 304L, 316L, cyangwa 317L.

Kurwanya Umunaniro Kurwanya
Alloy 2205 duplex idafite isahani yicyuma ikomatanya imbaraga nyinshi hamwe no kurwanya ruswa nyinshi kugirango itange imbaraga zumunaniro mwinshi.Porogaramu aho ibikoresho bitunganyirizwa bigengwa n’ibidukikije byangirika ndetse no gupakira ibintu bishobora kugirira akamaro imitungo ya 2205 duplex idafite ibyuma.
