316L phais steel: ib qho kev qhia dav dav
316L phais steelYog cov siv tau tshwj xeeb siv hauv kev siv tshuaj kho mob vim nws cov biocompatibility zoo siab, zoo nkauj corrosion tsis kam, thiab cov khoom siv neeg kho tshuab. Qhov no txo cov pa roj carbon, molybdenum-muaj variant ntawm 316 stainless hlau yog feem ntau siv ntawm kev phais cov twj, cog, cov hniav nyiaj hniav kub, thiab lwm yam kws kho mob. Hauv tsab xov xwm no, peb yuav delve rau hauv cov yam ntxwv tseem ceeb, cov ntawv thov, thiab cov qauv, thiab cov qauv sib txawv, ntxiv rau nws qhov sib txawv piv rau cov qauv 316L.
Dab tsi yog316L phais steel?
316L stainless hlau yog ib daim ntawv carbon-qis ntawm 316 stainless hlau, tsim los txo txoj kev pheej hmoo ntawm carbide nag lossis uas tuaj yeem ua rau muaj kev cuam tshuam rau kev txhim kho corrosion. Daim ntawv sau "L" sawv ntsug rau "cov pa roj carbon tsawg," uas qhia tias cov ntsiab lus carbon ntawm no alloy yog tsawg dua {}}. 03%. Qhov no muaj kev sib xyaw ua kom ntseeg tau tias 316L yog cov teeb tsa zoo heev rau kev xeb thiab tswj kev ua kom muaj kev ntseeg siab ntawm lub cev, thiab cov txheej txheem ua kom muaj menyuam kom tsis muaj menyuam.
316L phais cov hlau sib xyaw:
| Lub ntsiab | Cov ntsiab lus ntau (%) |
|---|---|
| Carbon (c) | Tsawg dua los yog sib npaug rau 0. 03 |
| Chromium (cr) | 17.0–19.0 |
| Npib tsib caug (ni) | 13.0–15.0 |
| Molybdenum (mo) | 2.25–3.00 |
| Manganese (MN), silicon (si), phosphorus (p), leej faj (s) | Cov Nqi |
Lub xub ntiag ntawmMolybdenum (mo)Txhim kho kom cov chloride-ntxias pitting corrosion, uas yog qhov tseem ceeb tshwj xeeb rau cov roj kho, cov cuab yeej kho mob.
Cov Khoom Siv Tseem Ceeb ntawm 316L phais cov hlau
1. Cov ntsiab lus carbon tsawg
TusCov ntsiab lus muaj roj carbon tsawghauv 316L tiv thaiv carbide nag lossis thaum pib vuam, uas yuav cuam tshuam rauintergranular corrosionnyob rau hauv cov chaw hnyav. Qhov no ua rau 316L mas tsim nyog rauWelded Kho Mob Kho Mobuas yuav tsum muaj kev tiv thaiv corrosion zoo heev ntawm welded pob qij txha.
2. Zoo heev corrosion tsis kam
316L lub corrosion tsis kam yog zoo dua rau ntau lwm cov hlau uas tsis muaj qhov tshwj xeeb hauv cov chloride ib puag ncig xws li cov uas pom hauv tib neeg lub cev. TusmolybdenumCov ntsiab lus hauv 316L muab nws zoo heev tiv taus raupitting thiab crevice corrosionUas yog muaj ntau hauv kev kho mob thiab kev phais thov.
3. Cov hlau tsis sib nqus
Vim nwsAUSTENITICTus qauv, 316L yogTsis muaj hlau nplaum, uas ua rau nws zoo tagnrho rau cov ntawv thov kev kho mob uas yuav tsum muaj kev sib nqus kev kuaj mob (MRI). Cov cuab yeej no kom ntseeg tau tias kev siv kev kho mob yuav tsis cuam tshuam nrog kev ntsuas tshuab.
Cov ntawv thov ntawm 316L phais
Kev phais cov twj: Scalpels, Force, Txiab, thiab Kev phais riam
Kev cog lus: Orthopedic kev cog lus, suav nrog pob txha screws, daim hlau, thiab txha caj qaum
Cov Cuab Yeej Siv Hniav: Dental Forticps, cov pa dej paus canal, thiab lwm yam cuab yeej kho hniav
Cheebtsam Kho Mob: Xws li cov li qub, twj, thiab cov khoom siv hauv ib puag ncig tsis muaj menyuam
