Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhovcov ntsiab lus ntawm nickel hauv316L stainless hlau, nws lub luag haujlwm hauv cov qauv ntawm cov hlau, thiab vim li cas qhov no tseem ceeb rau kev ua tau zoo, kev tiv thaiv corrosion, biocompatibility, thiab tus nqi.
Ua ib lub tuam txhab ua lag luam ntawm cov khoom siv stainless hlau,sakysteelPeb cog lus tias yuav muab cov khoom siv uas muaj kev pom tseeb thiab kev nkag siab txog kev siv tshuab. Cia peb saib ze dua ntawm 316L stainless hlau thiab lub luag haujlwm ntawm nickel hauv nws cov kev ua tau zoo.
1. Cov Tshuaj Lom Zem ntawm 316L Stainless Steel
316L stainless hlau yog ib feem ntawm covtsev neeg austeniticntawm cov hlau tsis xeb, uas tau txhais los ntawm lawv lub ntsej muag-centered cubic (FCC) siv lead ua qauv ruaj khov los ntawmnpib tsib.
Cov tshuaj lom neeg sib xyaw ua ke ntawm 316L yog:
-
Chromium (Cr): 16.0 – 18.0%
-
Nickel (Ni): 10.0 – 14.0%
-
Molybdenum (Mo): 2.0 – 3.0%
-
Cov pa roj carbon (C)≤ 0.03%
-
Manganese (Mn)≤ 2.0%
-
Silicon (Si)≤ 1.0%
-
Hlau (Fe): Sib npaug
LubCov ntsiab lus nickel ntawm 316L feem ntau yog nruab nrab ntawm 10 thiab 14 feem pua, nyob ntawm seb cov qauv tshwj xeeb thiab cov qauv uas tau ua raws li (ASTM, EN, JIS, thiab lwm yam).
2. Vim li cas thiaj ntxiv nickel rau hauv 316L Stainless Steel?
Nickel ua si ntau yamlub luag haujlwm tseem ceebHauv kev coj tus cwj pwm tshuaj lom neeg thiab kev kho tshuab ntawm 316L:
a) Kev Ruaj Ntseg ntawm Austenitic Structure
Nickel pab kom ruaj khovtheem austeniticntawm cov hlau tsis xeb, uas muab nws zoo heev formability, ductility, thiab toughness. Austenitic stainless hlau zoo li 316L tseem tsis yog magnetic thiab khaws lawv lub zog txawm tias nyob rau hauv cryogenic kub.
b) Kev Tiv Thaiv Kev Sib Tsoo Zoo Dua
Nickel, ua ke nrog chromium thiab molybdenum, txhim kho zoo heevkev tiv thaiv xeb, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj chloride ntau xws li:
-
Dej hiav txwv
-
Cov thoob tshuaj lom neeg
-
Cov khoom siv ua zaub mov
-
Cov cuab yeej phais thiab kho hniav
c) Kev Txhim Kho Weldability
Nickel pab txhawb rautxo qhov kev tawg yooj yimnyob rau hauv cov pob qij txha welded, tso cai rau 316L siv dav hauv cov qauv welded thiab cov kav dej tsis muaj kev kho cua sov tom qab vuam.
d) Lub Zog Kho Tshuab thiab Kev Ua Tau Yooj Yim
Nickel ua rau lub zog nce ntxivyield thiab tensile zogntawm cov hlau tsis muaj kev cuam tshuam nws qhov yooj ywm, ua rau 316L zoo tagnrho rau cov hlab ntsha siab, cov raj xa dej yooj ywm, thiab lwm yam khoom thauj khoom.
3. Qhov txawv ntawm 304 thiab 316L hauv cov ntsiab lus ntawm Nickel
Lwm cov hlau tsis xeb uas siv ntau yog304, uas kuj muaj nickel tab sis tsis muaj molybdenum. Qhov sib txawv tseem ceeb yog:
| Vaj tse | 304 Cov Hlau Stainless | 316L Stainless hlau |
|---|---|---|
| Cov ntsiab lus ntawm npib tsib xee | 8 – 10.5% | 10 – 14% |
| Molybdenum | Tsis muaj dab tsi | 2 – 3% |
| Kev Tiv Thaiv Kev Xeb | Zoo | Zoo heev, tshwj xeeb tshaj yog nyob rau hauv chlorides |
Vim nwscov ntsiab lus nickel thiab molybdenum ntau dua, 316L muaj kev tiv thaiv corrosion zoo dua piv rau 304.
4. Puas yog 316L Stainless Steel Magnetic?
