Itsva Yekuenzanisa Tafura yeStainless Simbi Magiredhi
Simbi isina tsvina inoshandiswa zvakanyanya muindasitiri yekugadzira yepasi rose, asi nekuda kwezviyero zvakasiyana uye nzira dzekupa mazita dzesimbi isina tsvina munyika dzakasiyana siyana nematunhu, kazhinji pane zvimwe zvipingamupinyi mukunzwisisa nekutaurirana. Kuitira kubatsira mabhizinesi nevatengi kuona zvirinani uye kusarudza zvinhu zvakakodzera, JIEHUANG yakanyora tafura yekuenzanisa yepasirese yemagiredhi esimbi isina tsvina. Tafura iyi inofananidza miyero mikuru yepasirese (yakadai seyeChina yeGB standard, United States'ASTM standard, Europe's EN standard uye Japan's JIS standard) yekukurumidza kutariswa pakusarudza nekutenga simbi isina tsvina. Izvi hazvigone chete kunyatso kuvandudza kugona kwekutenga kwemhiri kwemuganhu, asi zvakare kubatsira kuve nechokwadi uye kuenderana kwekusarudzwa kwezvinhu.

RFQ:
1. Chii chinonzi corrosion resistance yemhando dzakasiyana-siyana dzesimbi?
304 isimbi ine chinangwa chakajairwa iyo inoshandiswa zvakanyanya kugadzira midziyo uye zvikamu zvinoda kuita kwakanaka kwakazara (corrosion resistance uye formability). 301 simbi isina tsvina inoratidza basa riri pachena kuoma kana rakaremara uye rinoshandiswa muzviitiko zvakasiyana zvinoda simba rakakwirira.
302 Stainless simbi inongosiyana-siyana ye304 Stainless simbi ine yakakwira kabhoni yemukati, iyo inogona kugadzirwa kuti ive nesimba repamusoro kuburikidza nechando kukunguruka.
302B isimbi isina tsvina ine yakakwira silicon yemukati uye ine yakakwirira kupikisa kune yakakwirira-tembiricha oxidation. 303 uye 303Se simbi isina tsvina ine sulfuri uye selenium zvakateerana, iyo inoshandiswa muzviitiko zvinonyanya kuda kutemwa kwemahara uye kumusoro kwepamusoro. 303Se Stainless simbi inoshandiswawo kugadzira zvikamu zvinoda kupisa kupisa nekuti pasi pemamiriro ezvinhu akadai, iyi simbi isina tsvina ine basa rakanaka rinopisa.
304L mutsauko we304 simbi isina tsvina ine yakaderera kabhoni yemukati uye inoshandiswa muzviitiko zvinoda welding. Iyo yakaderera kabhoni yemukati inoderedza kunaya kwemacarbides munzvimbo inobatwa nekupisa pedyo neweld, uye kunaya kwecarbides kunogona kukonzera intergranular corrosion (weld erosion) yesimbi isina tsvina mune dzimwe nharaunda.
304N initrogen-ine simbi isina tsvina, uye nitrogen inowedzerwa kuwedzera simba resimbi.
305 uye 384 simbi isina tsvina ine yakakwira nickel yemukati uye ine yakaderera yebasa kuomeswa mitengo, ichiita kuti ive yakakodzera kune dzakasiyana zviitiko zvine zvakakwirira zvinodiwa zvekutonhora kuumbwa.
308 simbi isina tsvina inoshandiswa kugadzira simbi dzewelding.
309, 310, 314 uye 330 masimbi asina tsvina ese ane yepamusoro nickel uye chromium zviri mukati kuitira kuvandudza oxidation kuramba uye kukambaira kwesimbi pakupisa kwakanyanya. 30S5 uye 310S akasiyana e309 uye 310 simbi isina tsvina, musiyano chete ndewekuti iwo ane yakaderera kabhoni yemukati kuitira kuderedza kunaya kwecarbides pedyo neweld. 330 simbi isina tsvina ine yakanyanya kupikisa ku carburization uye kutyisa kwekushisa.
316 uye 317 simbi dzisina simbi dzine aruminiyamu, saka kupikisa kwavo kwegomba munzvimbo dzemugungwa nemumaindasitiri emakemikari kuri nani kupfuura iyo ye304 simbi isina tsvina. Pakati pazvo, 316 simbi isina tsvina ine zvakasiyana-siyana zvinosanganisira yakaderera-kabhoni Stainless simbi 316L, yakakwirira-simba Stainless simbi 316N ine nitrogen, uye mahara-kucheka Stainless simbi 316F ine yakakwira sulfur content.
321, 347 uye 348 simbi isina tsvina yakagadzikana netitanium, niobium, tantalum uye niobium zvakateerana, yakakodzera kune welding zvikamu zvinoshandiswa pakupisa kwakanyanya. 348 isimbi isina tsvina yakakodzera indasitiri yemagetsi enyukireya, uye ine zvimwe zvinorambidzwa pahuwandu hwetantalum necobalt.
2. Sei simbi isina tsvina iriwo magineti?
Mhinduro: Vanhu vanowanzo funga kuti magineti anogona kukwezva simbi isina tsvina kuti ione kunaka kwayo uye huchokwadi. Kana iyo isingakwezve magineti, inoonekwa seyakanaka uye yechokwadi; kana ichikwezva magineti, inoonekwa sekunyepedzera. Muchokwadi, iyi inzira ine divi rimwe chete, isingaite uye isiriyo yekuzivisa nzira.
Kune akawanda marudzi eStainless simbi, ayo anogona kukamurwa mumapoka akati wandei zvichienderana nechimiro chesangano patembiricha yekamuri:
1. Austenite: se304, 321, 316, 310, zvichingodaro;
2. Martensite kana ferrite: zvakadai se430, 420, 410, nezvimwewo;
Austenite isiri-magnetic kana isina simba remagineti, nepo martensite kana ferrite iine magineti.
Mazhinji esimbi isina tsvina inoshandiswa pakushongedza chubhu mapepa ndeye austenitic 304 zvinhu, izvo kazhinji zvisiri zvemagineti kana zvisina simba magineti. Nekudaro, nekuda kwekuchinja kwemakemikari kuumbwa kana akasiyana ekugadzirisa mamiriro akakonzerwa nekunyungudika, magineti anogonawo kuitika, asi izvi hazvigone kutorwa seyekunyepedzera kana kusakodzera. Chikonzero chii?
Sezvataurwa pamusoro apa, austenite isiri-magnetic kana isina simba remagineti, nepo martensite kana ferrite iine magineti. Pamusana pekuparadzaniswa kwechikamu kana kusagadziriswa kwekupisa panguva yekunyunguduka, zvishoma zvemartensite kana ferrite chimiro chichakonzerwa mu austenitic 304 simbi isina tsvina. Nenzira iyi, 304 simbi isina tsvina ichave isina simba remagineti.
Mukuwedzera, mushure mekushanda kunotonhora, chimiro chesangano che 304 simbi isina tsvina chichashandurawo kuva martensite. Iyo yakakura kutonhora kwekushanda deformation, iyo yakawanda martensite shanduko, uye yakakura magineti yesimbi. Semuyenzaniso, batch yesimbi mitsetse, painoburitsa Φ76 machubhu, hapana pachena magineti induction, uye painoburitsa Φ9.5 machubhu. Iyo magineti induction inova pachena nekuda kweiyo yakakura kutonhora beng deformation. The deformation of square and rectangular tubes yakakura kudarika iyo yeround tubes, kunyanya makona, uye deformation yakanyanyisa uye magnetism iri pachena.
Kubvisa zvachose magineti ye304 simbi yakakonzerwa nezvikonzero zviri pamusoro, yakakwirira-tembiricha yakasimba mhinduro kurapwa inogona kushandiswa kudzoreredza yakagadzika austenite chimiro, nekudaro kubvisa iyo magineti.
Zvinofanira kutaurwa kunyanya kuti magineti ye304 simbi isina tsvina inokonzerwa nezvikonzero zviri pamusoro yakasiyana zvachose nemagnetism yezvimwe zvinhu zvakadai se430 uye carbon steel, kureva, magnetism ye304 simbi inogara ichiratidza magnetism isina simba.
Izvi zvinotitaurira kuti kana simbi isina tsvina ine magnetism isina simba kana pasina magineti zvachose, inofanira kutongwa se 3-4 kana 316 zvinhu; kana yakafanana nemagnetism ye carbon steel, inoratidza magnetism yakasimba, saka inotongwa kuti haisi 304 zvinhu.
Tinokurudzira kuti kana uchitenga zvigadzirwa zvesimbi isina tsvina, unofanirwa kusarudza zvigadzirwa kubva kune vagadziri vane mbiri, usakara zvekuchipa, uye chenjera kunyengedzwa.
