Mhedziso yeDuplex Stainless Steel

Super duplex simbi isina simbi inosiyaniswa kubva kune akajairwa duplex mamakisi neyakagadziridzwa zvakanyanya inodzivirira corrosion. Icho chinhu chakanyanya kusanganiswa zvinhu zvine kukwirira kwakakwira kweanopesana necorrosive zvinhu senge chromium (Cr) uye molybdenum (Mo). Yekutanga super duplex Stainless simbi giredhi, S32750, inosanganisira yakawanda se28.0% chromium, 3.5% molybdenum, uye 8.0% nickel (Ni). Izvi zvikamu zvinopa kupikisa kwakasiyana kune zvinosvibisa, kusanganisira acids, chlorides, uye caustic mhinduro.

Kazhinji, super duplex stainless simbi dzinovaka pamusoro pezvakagadziriswa mabhenefiti e duplex mamakisi ane yakagadziridzwa kugadzikana kwemakemikari. Izvi zvinoita kuti ive giredhi rakakodzera rekugadzira zvinhu zvakakosha muchikamu chepetrochemical, senge zvinopisa kupisa, boilers, uye midziyo yekumanikidza.

Kurongeka kweDuplex Stainless Steel

l Rudzi rwekutanga imhando yakaderera alloy, ine mumiriri giredhi reUNS S32304 (23Cr-4Ni-0.1N). Iyo simbi haina molybdenum, uye iyo PREN kukosha ndeye 24-25. Inogona kushandiswa pachinzvimbo cheAISI304 kana 316 mukushushikana nekuora kwekudzivirira.

l Rudzi rwechipiri nderwemhando yepakati alloy, mumiriri brand UNS S31803 (22Cr-5Ni-3Mo-0.15N), iyo PREN kukosha ndeye 32-33, uye kushora kwayo kuri pakati peAISI 316L uye 6% Mo + N austenitic simbi isina tsvina.

l Rudzi rwechitatu nderwemhando yepamusoro yealloy, iyo inowanzo ine 25% Cr, molybdenum uye nitrogen, uye mamwe anewo mhangura netungsten. The standard giredhi UNSS32550 (25Cr-6Ni-3Mo-2Cu-0.2N), PREN kukosha ndeye 38-39, uye kushorwa kwemhando yesimbi iyi yakakwirira kupfuura ye22% Cr duplex simbi isina tsvina.

l Rudzi rwechina ndeye super duplex simbi isina tsvina, iyo ine yakakwira molybdenum uye nitrogen. The standard giredhi UNS S32750 (25Cr-7Ni-3.7Mo-0.3N), uye mamwe anewo tungsten nemhangura. Iyo PREN kukosha yakakura kupfuura makumi mana, iyo inogona kuiswa kune yakaoma yepakati mamiriro. Iyo ine yakanaka corrosion resistance uye mechanic comprehensive properties, inogona kuenzaniswa ne super austenitic stainless simbi.

Mabhenefiti eDuplex Stainless Steel

Sezvambotaurwa pamusoro, Duplex inowanzoita zvirinani pane imwe neimwe simbi mhando inowanikwa mukati meiyo microstructure. Zvirinani zvakati, musanganiswa wehunhu hwakanaka hunobva ku austenite uye ferrite zvinhu zvinopa mhinduro iri nani yehuwandu hwehuwandu hwakasiyana hwekugadzira mamiriro.

l Anti-corrosive properties - Mhedzisiro ye molybdenum, chromium, uye nitrogen pakuramba kwemarara kweDuplex alloys yakakura. Duplex alloys akati wandei anogona kuenzanisa uye kudarika anti-corrosive performance yeakakurumbira austenitic mamakisi anosanganisira 304 uye 316. Anonyanya kushanda pakurwisa mutswe uye gomba gora.

l Stress corrosion cracking - SSC inouya semhedzisiro yezvinhu zvakati wandei zvemuchadenga - tembiricha uye hunyoro ndizvo zvinonyanya kuoneka. Tensile stress inongowedzera dambudziko. Normal austenitic mamakisi anotapukirwa zvakanyanya nekunetsekana nekutsemuka - Duplex simbi isina tsvina haisi.

l Kuoma - Duplex yakasimba kudarika ferritic steels - kunyangwe pamatembiricha akadzikira nepo isingaenderane nekuita kwemagiredhi eaustenitic muchikamu ichi.

l Simba - Duplex alloys inogona kusvika ku2 nguva yakasimba kupfuura zvese austenitic uye ferritic zvimiro. Kusimba kwepamusoro kunoreva kuti simbi inoramba yakasimba kunyangwe nehupamhi hwakadzikira izvo zvinonyanya kukosha pakudzikisa huremu.
