Kawm paub txog ib hom khoom siv txhua hnub - 304}} stainless hlau
1. Cov khoom siv muaj pes tsawg
| Lub ntsiab | Cov ntsiab lus (%) | Lub luag hauj lwm |
|---|---|---|
| Chromium (cr) | 18–20% | Cov Ntawv Passive Oxide Txheej Rau Corrosion Kuj |
| Npib tsib caug (ni) | 8–10.5% | Txhim kho ductility thiab acid tiv taus |
| Carbon (c) | Tsawg dua los yog sib npaug rau 0.08% | Precludes rhiab kawg (chromium carbide nag lossis daus) |
| Manganese (mn) | Tsawg dua los yog sib npaug rau 2.0% | Txhim Kho Kev Ua Haujlwm |
| Hlau (FE) | Seem | Cov Qauv Txheej Txheem |
Cov Qauv Tsim:
ASTM A240: Uns s30400
ISO 15510: X5Cni18-10
2. Cov yam ntxwv tseem ceeb
A. Corrosion Kuj
Oxide Txheej: Tus kheej {-} kho cov duab zaj duab xis tiv thaiv oxidation thiab me me tshuaj.
Kev txwv: Txom Nyem rau Chlorides (xws li, qab ntsev) thiab cov kua qaub muaj zog acids (Ph<4).
B. Kev Ua Haujlwm Txhua Yam
Lub zog tensile: 515 MPa (min)
Paib lub zog: 205 MPa (min)
Kev nyuaj: 70-90 hrb (rockwell b)
C. Kev ntsuas hluav taws xob sib raug zoo
Kev sib sib zog nqus duab: Zoo heev rau Seamless sab hauv lub khob tsim.
Vuam: Tig / Laser Vuam khaws corrosion corrosion tsis kam nyob rau hauv tshav kub - cuam thaj chaw.
3. Kev tsim kho cov txheej txheem rau cov hwj
Ntawv Txoj Kev Ua: Txias {-}} rolled 304 nplooj ntawv (0.5-0.8 mm thickness) sticked rau khob daim.
Seamless teeb duab: Tshem tawm cov pob qij txha welded los tiv thaiv kev xeb corrosion.
Kev Hluav Taws Xob: Dissolves saum npoo hlau, enriching chromium concentration rau txhim kho passivation.
Passivation: Nitric acid kho kom tshem tawm cov paug thiab ntxiv dag zog rau cov oxide txheej.
4. Qhov zoo rau lub cheb tsev
| Yam zoo | Kev pab |
|---|---|
| Huv Si | Tsis - porous, yooj yim rau kev tawm suab nrov |
| Saj tsis ncaj neutrality | Tsis muaj xim hlau tom qab hloov |
| Yam ruaj khov | Tsis kam nrog kev kho hniav thiab deformation |
| Tus Nqi Muaj Zog | Qhov kev ua tau zoo - rau - tus nqi piv |
5. Kev siv tau
Kev Kuaj Corrosion: 72-teev ntsev tsuag tshuaj (Astm B117) - tsis muaj xeb liab.
Lead / Nickel Leaching: Ua raws liFDA 21 CFR 175.300thiabEU 10/2011.
Xim hlau dua: Grain loj (saab loj)
6. Qhov txwv & mitigations
| Tsab | Lus teb |
|---|---|
| Chloride pitting | Zam kev ntev - lub sij hawm sillwwwater cia; Siv 316 stainless rau ib puag ncig marine |
| Acid corrosion | Txwv tsis pub nthuav tawm cov kua txiv ntoo / vinegar; Tej hub txheej rau acidic dej |
| Nickel rhiab | Pom zoo 304L (cov pa roj carbon qis) lossis titanium rau kev ua xua-} prone cov neeg siv |
7. Kev lag luam kev siv
Niaj hnub dej fwj txhua hnub: Hydro flask qauv qhov ncauj, S'well Classic.
Cov Khoom Noj & Dej Haus: Noj su, tshuaj yej infusers.
Lub tshuab nqus hluav taws xob flasks: Universal hloov rau cov hwj yas.
8. Cov Lus Qhia Saib Xyuas
Ntxuav: Tshuaj txhuam hniav me + mos muag; Tsis txhob tshuaj chlorine ua kom dawb.
TO TAIS RHOOS: Soak nrog diluted vinegar (tsawg dua los yog sib npaug rau 30 mins).
Chaw ntim khoom: Khaws kom qhuav kom tiv thaiv cov chaw dej.
304 stainless hlau tseem nyob ntawmKev Lag Luam Benchmarkrau kev ua tau zoo ntawm kev ua tau zoo, kev nyab xeeb, thiab pheej yig hauv kev ntxuav khoom. Nws ua raws nrog cov zaub mov thoob ntiaj teb - Cov qauv kev nyab xeeb thiab rov ua dua tshiab) ntxiv rau cov khoom siv ntau ntxiv rau cov khoom lag luam hydration.
