304 simbi isina tsvina ndiyo inonyanya kushandiswa chromium-nickel simbi isina tsvina. Sesimbi inoshandiswa nevakawanda, ine yakanaka corrosion resistance, heat resistance, yakaderera tembiricha simba uye mechanical properties; ine yakanaka inopisa inoshanda senge kutsika nekukotama, uye haina kupisa kurapwa kuomesa chiitiko (kushanda tembiricha -196℃～800℃).

Simbi isina nguraInox 304(AISI 304) ndiyo inonyanya kushandiswa mhando yesimbi isina tsvina nekuda kweiyo yakaenzanirana mechanika uye kemikari.

Heano maitiro ayo akakosha einox 304:

1. Corrosion Resistance

High resistance kune nguramunzvimbo dzakasiyana siyana, kunyanya mamiriro emuchadenga uye kusangana nemakemikari anoparadza senge acids uye chlorides.

Inoita zvakanaka munzvimbo dzine hunyoro kana hunyoro.

2. Composition

Rine dzinenge18% chromiumuye8% nickel, inowanzonzi18/8 simbi isina tsvina.

Inosanganisirawo zvishoma zvekabhoni (max 0.08%), manganese,uyesilicon.

3. Mechanical Properties

Kusimba simba: Around515 MPa (75 ksi).

Goho simba: Around205 MPa (30 ksi).

Elongation: Kusvika pa40%, zvichiratidza kuumbwa kwakanaka.

Kuoma: Yakapfava uye inogona kushanda-yakaomeswa kuburikidza nekushanda kunotonhora.

4. Formability uye Kugadzirwa

Yakagadzirwa nyoremune akasiyana maumbirwo nekuda kwekunaka kwayo ductility, ichiita kuti ive yakanakira kudhirowa kwakadzika, kudzvanya, uye kukotama.

Weldability yakanaka, kunyanya yakakodzera kune ese akajairwa welding matekiniki.

Kutonhora kushanda: Inogona kusimbiswa zvakanyanya nekushanda kunotonhora, asi kwete kuburikidza nekupisa kurapwa.

5. Heat Resistance

Oxidation kurambakusvika pa870°C (1598°F)mukushandiswa kwepakati uye kusvika925°C (1697°F)mubasa rinoramba riripo.

Hazvikurudzirwe kushandiswa munzvimbo dzinosanganisira kugara uchitarisana netembiricha iri pamusoro425-860°C (797-1580°F)nekuda kwenjodzi yekunaya kwecarbide, iyo inogona kuderedza kushomeka kwekudzivirira.

6. Hutsanana uye Aesthetic Chitarisiko

Zviri nyore kuchenesa nekuchengetedzanekuda kwenzvimbo yayo yakatsetseka, iyo inopesana nekukura kwebhakitiriya, ichiita kuti ive yakanaka pakugadzira chikafu uye midziyo yekicheni.

Inochengetedza inopenya uye inoyevedzapamusoro pekupedzisira, zvichiita kuti ive yakakurumbira mukuvaka, midziyo yekicheni, uye maapplication ekushongedza.

7. Non-Magnetic

Kazhinjiisiri-magneticmune yayo annealed fomu, asi inogona kuita zvishoma magineti mushure mekutonhora kushanda.

8. Applications

Inoshandiswa zvakanyanya mumidziyo yekugadzira chikafu, midziyo yekubikira, midziyo yemakemikari, yekuvharisa yekuvaka, uye michina yekurapa.

Yakanakira nharaunda inoda yakanaka corrosion kuramba, kusimba, uye kureruka kwekugadzira.

9. Mutengo-Kubudirira

Isingadhure pane yepamusoro-giredhi Stainless simbi (se316) apa ichipa zvakanakisa zvivakwa zvese, izvo zvinoita kuti ive yakakurumbira kune akawanda maapplication.

10.Kupokana kune Acids

Inopikisa kune akawanda organic acidsuye zvinyoro corrosive inorganic acids, kunyange ingasaita zvakanaka munzvimbo dzine acidic kana chloride-rich (semvura yegungwa), uko simbi isina tsvina 316 inodiwa.

Inox 304 isarudzo yakanakisa-yakatenderedza simbi isina tsvina kune dzakasiyana siyana nharaunda uye mashandisiro, kuenzanisa mutengo, kusimba, uye kuita.

Zvakanakira uye maitiro einox 304:

1. Kunyanya kupisa kwekushisa
304 simbi isina tsvina inodiwa nevanhu vazhinji nekuda kwezvikonzero zvakawanda. Semuenzaniso, ine yakanaka yakakwirira tembiricha kuramba, iyo isingaenzaniswi neyakajairwa Stainless simbi. 304 simbi isina tsvina inogona kumira tembiricha yakakwira kusvika 800 madhigirii uye inogona kushandiswa muzviitiko zvakasiyana muhupenyu.

2. Corrosion resistance
304 simbi isina tsvina zvakare yakanaka kwazvo mukupokana nekuora. Nekuda kwekuti inoshandisa chromium-nickel elements, ine zvimiro zvemakemikari zvakatsiga uye haisi nyore kuita ngura. Nokudaro, 304 simbi isina tsvina inogona kushandiswa sechinhu chinorwisa-corrosion.

3. High kuoma
304 simbi isina tsvina ine hunhu hwekuoma kwakakwirira, izvo zvinozivikanwa nevanhu vazhinji. Naizvozvo, vanhu vanozozvigadzira kuita zvigadzirwa zvakasiyana, uye mhando yechigadzirwa zvakare yakakwira.

4. Low lead content
Chimwe chikonzero chekusarudza 304 simbi isina tsvina ndechekuti ine mutobvu mushoma uye haina kukuvadza kumuviri. Nokudaro, inonziwo chikafu-giredhi simbi isina tsvina uye inogona kushandiswa zvakananga kugadzira midziyo yezvokudya.

Nei inox 304 ndeimwe yeanonyanya kushandiswa uye anozivikanwa magiredhi esimbi isina tsvina

Inox 304 ndeimwe yeanonyanya kushandiswa simbi isina simbi mamakisi nekuda kwezvinhu zvakati wandei zvakakosha:

1. Corrosion Resistance

• Inopa kupikisa kwakanakisa kumarara munzvimbo dzakasiyana siyana, zvichiita kuti ive yakakodzera kune ese arimukati uye ekunze application.

2. Versatility

• Kuumbwa kwayo kwakaringana kunobvumira kushandiswa mumaindasitiri akati wandei, kusanganisira chikafu nechinwiwa, zvivakwa, zvemotokari, uye zvekurapa.

3. Zvakanaka Mechanical Properties

• Iyo ine yakakwira tensile simba uye yakanaka ductility, ichiigonesa kumirisana nemakanika kushushikana uye deformation pasina kutyora.

4. Kusununguka Kwekugadzira

• Inox 304 inogadzirwa zviri nyore uye inoumbwa kuita maumbirwo nehukuru hwakasiyana, izvo zvinorerutsa maitiro ekugadzira.

5. Weldability

• Inogona kugadzirwa nyore nyore uchishandisa ese akajairwa matekiniki, ichiita kuti ive yakakodzera kune zvimiro zvekushandisa.

6. Hutsanana Properties

• Nzvimbo yaro yakatsetseka uye kuramba kune mabhakitiriya inoita kuti ive yakanaka pakugadzira chikafu uye kushandiswa kwekurapa, uko hutsanana hunokosha.

7. Mutengo-Kubudirira

• Nepo ichipa zvivakwa zvakanakisa, kazhinji isingadhure pane mamwe masimbi emhando yepamusoro, zvichiita kuti ive sarudzo ine hupfumi kumapurojekiti mazhinji.

8. Non-Magnetic

• Mune mamiriro ayo anealed, haisi-magnetic, iyo yakakosha kune mamwe maapplication uko magineti inogona kunetsa.

9. Aesthetic Appeal

• Iyo inochengetedza inoyevedza kupera, ichiita kuti ive yakakodzera kune yekuvaka uye yekushongedza application.

10.Global Kuwanikwa

• Seyakajairwa alloy, inogadzirwa zvakanyanya uye inowanikwa zviri nyore, zvichiita kuti kutsvaga kuve nyore kune vanogadzira nevatengi.

Hunhu uhwu hunobatanidza kuita inox 304 ive yekuenda-kune zvinhu zvakasiyana-siyana zvekushandisa, zvichiita kuti ishandiswe zvakanyanya uye izivikanwe.

Mhedziso:

Inox 304 kana Stainless Steel 304 inozivikanwa nekunaka kwayo kusinga corrosion, kugoneka kwakanaka uye kusimba kwepamusoro. Iyo inowanzo ine 18% chromium uye 8% nickel uye inokodzera kuwanda kwekushandisa. Zvinhu izvi zvinoita kuti ive giredhi resimbi rinoshandiswa zvakanyanya pasi rose.
