2205 Duplex Overview
Duplex 2205 initrogen inowedzerwaduplex simbi isina tsvinaiyo yakagadzirwa kurwisa matambudziko akajairika ekuora akasangana ne300 akatevedzana masimbi asina tsvina."Duplex" inotsanangura mhuri yesimbi isina tsvina isina austenitic yakazara, se304 isina tsvina, kana kuti ferritic chete, se430 isina tsvina.Chimiro che2205 duplex simbi isina tsvina ine austenite madziva akakomberedzwa neinoenderera ferrite chikamu.Mune annealed mamiriro, 2205 ine inenge 40-50% ferrite.Inowanzonzi giredhi rebhiza rebasa, 2205 ndiyo giredhi rinonyanya kushandiswa mumhuri ine duplex yesimbi isina tsvina.
2205 duplex simbi isina tsvina yakamonerwa tubing/capillary tubing
Kushandiswa kwe2205 Duplex Stainless simbi kunofanira kuganhurirwa kune tembiricha iri pasi pe600° F. Kuwedzerwa tembiricha yakakwirisa kuratidzwa kunogona kukanganisa 2205 stainless.

Corrosion Resistance
2205 duplex Stainless simbi inodhura mhinduro kune akawanda maapplication uko mazana matatu akateedzana masimbi asina tsvina anotapukirwa ne chloride stress corrosion kuparuka.Stress corrosion cracking inoitika kana simbi dzisina tsvina dzinenge dziri pasi pekunetsekana, ichisangana nemhinduro dzine ma chlorides.Kuwedzera tembiricha kunowedzerawo kukonzeresa kwesimbi isina tsvina yekusimbisa ngura kutsemuka.
Kubatanidzwa kwechromium, molybdenum nenitrogen kunopa kumira kwakanaka kwe2205 kune chloride pitting uye crevice corrosion.Kupokana uku kwakakosha zvakanyanya kumasevhisi akadai senzvimbo dzemugungwa, mvura ine brackish, mashandiro anoita bleaching, akavharwa loop mvura masisitimu uye mamwe maapplication ekugadzirisa chikafu.Iyo yakakwira chromium, molybdenum uye nitrogen zviri mukati me2205 zvinopa kushora kwepamusoro kune akajairwa simbi isina tsvina, senge, 316L uye 317L munzvimbo zhinji.
