Kuongorora kweDuplex Stainless Simbi

Super Duplex Stainless Simbi yakasarudzika kubva ku standard duplex makiredhi neyakainikwanira zvakanyatsovandudzwa zvinhu-zvinodzivirira. Icho chinhu chakarongeka chakarongeka neakasimudzirwa nekukwirisa zvinhu zveanti-zvinokatyamadza zvakadai se chromium (cr) uye molybdenamu (mo). Iyo yekutanga super duplex stainless simbi giredhi, ST32750, inosanganisira yakawanda se 28.0% chromium, 3.5% molybdenum, uye 8.0% nickel (ni). Izvi zvikamu zvinopa kudzikisira kwakasiyana kune vamiriri vanodzora, kusanganisira Acids, chlorides, uye mhinduro dzemukati.

Kazhinji, Super Duplex Stainless Steels inovaka pane yakapihwa mabhenefiti eCuplex mamakisi ane akagadziriswa makemikari kugadzikana. Izvi zvinoiita giredhi rakakodzera rekuita kuti zvigadzirise zvikamu zve petrochemical, sekutsinhana kwerudzi rwekupisa, boilers, uye kudzvanywa midziyo yemidziyo.

Kuongororwa kweDuplex Stainless Simbi

l iyo yekutanga mhando ndeye yakaderera ley mhando, ine giredhi rekumiririra reMunyudhi weS.2304 (23cr-4Ni-0.1n). Simbi haina molybdenum, uye kukosha kwekutanga ndeye 24-25. Inogona kushandiswa panzvimbo yeAII304 kana 316 mukushamwaridzana kupokana.

l Mhando yechipiri ndeyemhando yepamusoro yemhando yerudzi, iyo inomiririra brand isingamunyepedzeri

l Type yechitatu iri yemhando yepamusoro yemhando, iyo inowanzove ne25% cr, molybdenum ne nitrogen, uye vamwe zvakare vane ndarira uye tungsten. Iyo yakajairwa giredhi Unss32550 (25cr-6mo-3MO-3MO-2MO-0.29

l iyo yechina mhando is super duplex simbi simbi, iyo ine yakakwira molybdenum uye nitrogen. Iyo yakajairwa giredhi iri under s32750 (25cr-7ni-3.7mo-0,7mo-0.3n), uye vamwe zvakare vane tungsten uye mhangura. Iyo yekutanga kukosha yakakura kupfuura makumi mana, iyo inogona kuiswa kune yakaomesesa mamiriro epakati. Iyo ine yakanaka kurwisa kurwisa uye michina yakazara zvinhu, izvo zvinogona kufananidzwa neyekuenzaniswa neyeusimbe autenitic stainless simbi simbi.

Zvakanakira Duplex Stainless Simbi

Sezvakataurwa pamusoro, duplex inowanzoita zvirinani pane mhando dzeSimbi dzeSimbi dzinowanikwa mukati mercanture yayo. Zvirinani zvati, Iko kusanganiswa kwehunhu hwakanaka kunouya kubva kuAustenite uye Elrite Zvinhu zvinopa mhinduro iri nani yehuwandu hwehuwandu hwehuwandu hwemamiriro akasiyana ekugadzira.

l Anti-Curosive Properties - Mhedzisiro yeMolybdenum, Chromium, uye nitrogen pane Corrosion Rishance yeDuplex Alloys ane zvakawanda. Vanoverengeka vanoverengeka voliys vanogona kuwirirana uye kupfuudza anti-corrosives yekuzivikanwa kweAustenitic mamakisi anosanganisira 304 uye 316. Ivo vanonyanya kushanda pamusoro peClevice uye posta posta.

L Anoshungurudza Corrosion Kurovera - SSC inouya semhedzisiro yezvinhu zvinoverengeka zvematikirwo - tembiricha uye humidity kuve inonyanya kuvonekwa. Kushushikana kwetenile kunongowedzera dambudziko. Zvakajairika Austenitic mamakisi anokundwa zvakanyanya kune kushamisika corrosis - duplex simbi isina.

l kutenya - duplex kwakasimba kupfuura steels steels - kunyangwe pakudziya kwepazasi apo hakunganyatsoenderana nekuita kweAustenitic mamakisi mune ichi chikamu.

l Simba - Duplex Alloys dzinogona kusvika kaviri kusimba pane zvese zvinosimba pane zvese zveAustenitic uye ferritic zvivakwa. Simba repamusoro rinoreva kuti simbi inosara yakasimba kunyangwe yakaderedzwa ukobvu iyo inonyanya kukosha yekudzora uremu huwandu.
