Simbi isina tsvina isarudzo yakakurumbira yekugadzira zviridzwa.Kudzidza nezve simbi isina tsvina kunogona kubatsira vashandisi vezviridzwa kuti vave nehunyanzvi pakusarudza nekushandisa zviridzwa nemazvo.
Simbi isina tsvina, inowanzopfupikiswa seSS, inokwanisa kushingirira pakusangana nemhepo, chiutsi, mvura, uye zvimwe zvinyoro zvinopisa.Zvichakadaro, simbi inokwanisa kuramba mhedzisiro yekuora kwemakemikari kubva kuzvinhu zvakaita seasidhi, alkali, munyu, uye mamwe makemikari etchants, inozivikanwa seasidhi-resistant simbi.
Simbi isina simbi, inozivikanwawo sesimbi isina simbi isina asidi, inogona kumira nemhepo, chiutsi, mvura, uye zvinhu zvinopisa zvinyoro.Zvisinei, zvakakosha kuti uzive kuti haisi yese simbi isina tsvina inopesana nemakemikari ekuora.Kune rumwe rutivi, acid-resistant simbi yakagadzirirwa kurwisa mhedzisiro yemakemikari media senge acid, alkali, uye munyu.Kupokana kwekupokana kwesimbi isina tsvina kunotsanangurwa nealloying zvinhu mukati mesimbi.
Common classification
Kazhinji yakakamurwa ne metallographic organisation:
Munzvimbo yesangano remetallographic, simbi yenguva dzose inogara yakakamurwa mumapoka matatu: Austenitic Stainless simbi, ferritic Stainless simbi, uye martensitic Stainless simbi.Aya mapoka anoumba hwaro, uye kubva ipapo, biphase simbi, kunaya-yakaomeswa simbi isina tsvina, uye yakakwirira alloy simbi ine isingasviki 50% iron yakagadziridzwa kuti isangane nezvinodiwa uye kuita zvimwe zvinangwa.
1, Non-Magnetic Stainless Simbi
Mhando iyi yesimbi isina tsvina ine crystal structure inozivikanwa se austenitic, iyo inonyanya kusimbiswa kuburikidza nekushanda kunotonhora.Haisi magineti, asi iyo 200 ne300 yakatevedzana nhamba, senge 304, inowanzoshandiswa neAmerican Iron uye Steel Institute kuona iyi simbi.
2, Simbi isina Stainless Yakagadzirwa Kazhinji neSimbi
Iyi mhando yesimbi isina tsvina inonyanya kuve nekristaro chimiro chinodzorwa neferrite (chikamu A), iyo ine magineti.Iyo kazhinji haigone kuomeswa kuburikidza nekudziya, asi kushanda kunotonhora kunogona kukonzera kuwedzera kudiki kwesimba.IAmerican Iron and Steel Institute inotsanangura 430 uye 446 semuenzaniso.
3, Yakaoma Stainless Simbi
Iyi mhando yesimbi isina tsvina ine crystal structure inonzi martensitic iyo ine magnetic.Iyo mechanical properties inogona kuchinjwa kuburikidza nekupisa kurapwa.The American Iron and Steel Institute inotaura nezvayo se410, 420, uye 440. Martensite inotanga ne austenitic structure pakupisa kwakanyanya uye inogona kushanduka kuita martensite (kureva, inowedzera kuoma) kana ichitonhora nekumhanya kwayo kusvika kune tembiricha yekamuri.
4, Duplex Stainless Simbi
Mhando iyi yesimbi isina tsvina ine musanganiswa we austenitic uye ferritic structures.Chikamu chechikamu chidiki muchimiro chinowanzopfuura 15%, zvichiita kuti ive magineti uye inokwanisa kusimbiswa kuburikidza nekushanda kunotonhora.329 muenzaniso unozivikanwa werudzi urwu rwesimbi isina tsvina.Kana ichienzaniswa neaustenitic Stainless simbi, duplex simbi inoratidza simba rakakura uye kuwedzera kunoshamisa mukupokana kune intergranular corrosion, chloride stress corrosion, uye point corrosion.
5, Stainless Simbi ine Kunaya Kwemvura Kuomesa Kugona
Iyi mhando yesimbi isina tsvina ine matrix angave austenitic kana martensitic uye inogona kuomeswa kuburikidza nekunaya kwemvura kuoma.The American Iron
uyeSteel Institute inopa mazana matanhatu akateedzana manhamba kune aya masimbi, akadai se630, ayo anozivikanwawo se17-4PH.
Kazhinji, kunze kwealloys, austenitic simbi isina tsvina inopa yakasarudzika corrosion kuramba.Kunzvimbo dzisingaite ngura, ferritic Stainless simbi inogona kushandiswa, nepo munzvimbo dzine ngura zvinyoro-nyoro panodiwa simba rakawanda kana kuoma, martensitic Stainless simbi uye kunaya kwakaomarara simbi isina tsvina ndiyo sarudzo dzakakodzera.
Zvimiro uye nzvimbo dzekushandisa

Kusiyanisa ukuru
1, nekuti muchina wesimbi mukugadzira, kupisa kwemupumburu kunoratidzika kushoma, zvichikonzera ukobvu hwekumisikidzwa kwebhodhi kutsauka, kazhinji gobvu pamativi ese ehutete.Pakuyera ukobvu hwebhodhi, nyika inotaura kuti chikamu chepakati chemusoro webhodhi chinofanira kuyerwa.
2, chikonzero chekushivirira chiri maererano nemusika uye kudiwa kwevatengi, kazhinji kwakakamurwa kuva kushivirira kukuru uye kushivirira kudiki: semuenzaniso,
Imhando ipi yesimbi isina tsvina isiri nyore kuita ngura?
Pane zvinhu zvitatu zvakakosha zvinokanganisa simbi isina ngura:
1, zviri mukati me alloying elements.
Impact yeAlloying Elements Kazhinji, simbi ine inokwana 10.5% chromium inoratidza kuramba ngura.Uyezve, simbi isina tsvina ine mazinga epamusoro echromium uye nickel, sezvinowanikwa mu 304 simbi ine 8-10% nickel uye 18-20% chromium, inoratidza yakakwidziridzwa kusaita ngura uye kazhinji inoshingirira kuita ngura mumamiriro ezvinhu chaiwo.
2. Kufurira kweSmelting Process paCorrosion Resistance
Iyo corrosion resistance yesimbi isina simbi inogonawo kukanganiswa nekunyungudika muzvivako zvekugadzira.Miti mikuru-yesimbi isina tsvina yakashongedzerwa tekinoroji yepamberi uye michina yemazuva ano inogona kuve yakagadzikana uye yakavimbika mhando yechigadzirwa kuburikidza nekudzora kwakaringana kwealloying zvinhu, kubviswa kwetsvina kunoshanda, uye kutonga kwakaringana kwekutonhora kwekutonhora kwebillet.Izvi zvinoguma nemhando yepamusoro yemukati uye kuderedza kubatwa ne ngura.Sezvineiwo, zvigayo zvidiki zvesimbi zvine midziyo yechinyakare uye tekinoroji inogona kunetseka kubvisa tsvina panguva yekunyungudutswa, zvichitungamira mukuora kusingadzivisike kwezvigadzirwa zvavo.
3. mamiriro ekunze, mamiriro ekunze akaoma uye anofefetedza mhepo haisi nyore kuita ngura.
Mamiriro ekunze kwezvakatipoteredza, kunyanya yakaoma uye inofefetera zvakanaka, haikurudzire kuumbwa kwe ngura.Sezvineiwo, huwandu hwehunyoro hwemhepo, mamiriro ekunze ekunaya kwenguva refu, kana nharaunda dzine pH yakakwira mazinga anogona kutungamirira kukugadzira ngura.Kunyange 304 simbi isina simbi inova ngura kana ichiiswa pasi pemamiriro ekunze akaipa.
Simbi isina tsvina inoita ngura nzvimbo yekubata nayo?
1. Nzira dzemakemikari
Shandisa nzira dzemakemikari dzakaita sepickling paste kana kupfapfaidza kufambisa kupfuudzazve kwenzvimbo dzine ngura, kugadzira chromium oxide firimu rinodzoreredza kusaita ngura.Kutevera pickling, kunyatsogeza nemvura kwakakosha kubvisa zvese zvinosvibisa uye masara easidhi.Pedzisa nzira yekurapisa nekukwenenzvera nemidziyo yakakodzera uye nekusimbisa nenamo.Kune madiki madiki anotaridza ngura, musanganiswa we1: 1 wepeturu nemafuta unogona kuiswa nemucheka wakachena kubvisa ngura.
2. Mechanical nzira
Kushandiswa kwejecha kuputika, girazi kana ceramic particle shot blast, abrading, brushing, uye polishing inzira dzemuviri dzekubvisa hutachiona hwakasiiwa nekumbokwenenzverwa kana kuita abrading.Chero nzira yekusvibiswa, kunyanya yekunze iron particles, inogona kutungamira mukuora, kunyanya munzvimbo dzakanyorova.Saka, zvinokurudzirwa kuita kucheneswa kwepanyama kwenzvimbo pasi pemamiriro akaoma.Izvo zvakakosha kuti uzive kuti kushandiswa kwemaitiro emuviri kunogona chete kubvisa kusvibiswa kwepamusoro uye hakushandure iyo inherent corrosion resistance yezvinyorwa.Nekuda kweizvozvo, zvinokurudzirwa kupedzisa chirongwa ichi nekukwenenzvera nemidziyo yakakodzera uye nekusimbisa newakisi yekupolisha.
