Maplate esimbi asingatsvigiri e201 ne304 ndiwo maviri emhando dzinonyanya kushandiswa musimbi isingatsvigiri yeaustenitic. Musiyano wavo mukuru uri mukugadzirwa kwemakemikari (nickel nechromium), izvo zvinotungamira kune kusiyana kwakasiyana mukudzivirira ngura, hunhu hwemakanika, mutengo, uye mamiriro ekushandiswa. Pasi apa pane kuenzanisa kwakadzama:
1. Musiyano Mukuru: Kuumbwa kweMakemikari
Nickel (Ni) nechromium (Cr) ndizvo zvinhu zvakakosha pakudzivirira ngura yesimbi isingasvibi. Musiyano uripo pakati pezvinhu izvi ndiwo musiyano mukuru uripo pakati pemhando mbiri idzi:
| Giredhi | Zviri Mukati meChromium (Cr) | Zviri Mukati meNickel (Ni) | Zviri MuManganese (Mn) | Kabhoni (C) Zviri Mukati | Chinhu Chekutsiva |
|---|---|---|---|---|---|
| 201 Simbi Isina Zvisimbiso | 16%–18% | 3.5%–5.5% | 5.5%–7.5% | ≤0.15% | Inoshandisa manganese yakawanda kutsiva chikamu chenickel kuderedza mitengo |
| 304 Simbi Isina Zvisimbiso | 18%–20% | 8%–10.5% | ≤2% | ≤0.08% | Yakawanda nickel uye chromium, hapana chinotsiva manganese |
2. Kusiyana Kwakakosha Kwekushanda
(1) Kuramba Kuora
- 201 Simbi Isina Zvisimbiso: Inodzivirira ngura zvishoma. Inogona kungotsungirira mamiriro ekunze akaoma kana mamiriro ekunze ane hunyoro zvishoma. Inowanzobatwa nengura munzvimbo dziri kumahombekombe, dzine acid-alkali, kana dzine munyu wakawanda, kunyanya panzvimbo dzine weld.
- 304 Simbi Isina Zvisimbiso: Inodzivirira ngura zvakanyanya. Inogona kudzivirira hunyoro, acid isina simba uye alkalis, uye kukanganiswa nemvura yekunze. Ndiyo sarudzo huru yekushandisa chikafu chepamusoro uye chemazuva ese, ichizadzisa zvinodiwa zvezuva nezuva zvisingakuvadzi ngura.
(2) Zvimiro zveMakanika
- 201 Simbi Isina Zvisimbiso: Kuomarara kwakanyanya uye simba rayo rakati kurei, asi kusimba kwayo kuri pasi pe304. Inowanzotsemuka panguva yekugadzirisa uye haina kunaka pakukotama nekutambanudza.
- 304 Simbi Isina Zvisimbiso: Inoshanda zvakanaka uye yakasimba, iri nyore kupeta, kudzvanya, uye kusundira. Haikanganisike kana kutsemuka mushure mekugadzirisa, zvichiita kuti ive yakakodzera mamiriro akaomarara ekugadzira.
(3) Kuramba Kupisa Kwakanyanya
- 201 Simbi Isina Zvisimbiso: Kudzivirira kupisa kwakanyanya kunosvika 300℃; inogona kuoxidation uye kushanduka kupfuura tembiricha iyi.
- 304 Simbi Isina Zvisimbiso: Kudzivirira kupisa kwakanyanya kunosvika 800℃, kunoshanda munzvimbo dzine tembiricha yepakati nepamusoro dzakadai semaovheni nematangi emukati memuchina wekupisa mvura.
(4) Mutengo
- 201 Simbi Isina Kugayiwa: Nekuda kwehuwandu hwayo hushoma hwe nickel, yakachipa ne30%–50% pane 304, zvichiita kuti ive giredhi resimbi isina kugayiwa.
- 304 Simbi Isina Zvisimbiso: Mutengo wakakwira, unoshanda sezvinhu zvakajairika zvekushandiswa kwezvinhu zvemhando yepamusoro uye zvemhando yepamusoro yechikafu.
3. Kuenzanisa Mamiriro Ekushandisa
| 201 Zvikumbiro zveSimbi Isina Stainless Plate | 304 Zvishandiso zveSimbi Isina Stainless Plate |
|---|---|
| Kushongedza mukati memba kwakaoma (mafuremu emasuo, masherufu, zvikwangwani) | Midziyo yekicheni (masinki, midziyo yekicheni, makabati ekuuraya utachiona) |
| Zvikamu zvechivako zvisingatakuri mutoro, machira ekudzivirira, mambure ekudzivirira kuba | Midziyo yekugadzira chikafu, zvishandiso zvekurapa, mapaipi emvura yekunwa |
| Fenzi dzekunze dzisinganyanyi kudiwa (nzvimbo dzisina ngura yakawanda/dzisina kumahombekombe) | Madziro emaketeni ekunze, madziro emabharukoni, matangi emukati emuchina wekudziisa mvura |
| Masherufu ekuchengetera zvinhu kwenguva pfupi, ngoro dzemaoko | Matangi emakemikari, zvinhu zvekuchenesa, maflask evacuum |
4. Mazano ekukurumidza ekuziva
- Kunyudzwa kweMagineti: 201 ine huwandu hwakawanda hwemanganese, zvichikonzera simba remagineti kupfuura 304, saka yakabatana zvakanyanya negineti. 304 haina simba remagineti kana simba remagineti.
- Kuongorora Zvinoonekwa: 201 ine kupenya kwakanyanya pamusoro uye inowanzoita ngura, nepo 304 ine nzvimbo yakajeka uye yakachena isingakuvadzi ngura mushure mekushandiswa kwenguva refu.
- Kuedzwa kweKemikari: Shandisa mvura yekuziva simbi isingatsvi. Kana ikadonhedzwa paplate, 201 ichatsvuka nekukurumidza, ukuwo 304 isingaratidzi kuchinja kweruvara pachena (kunyatsorongeka, kwakakodzera kuongororwa panzvimbo yacho).
