AISI 316 thiab AISI 317yog ob qho tib si austenitic stainless hlau. Thaum Alloy 316 thiab 317 qhia qhov zoo sib xws li austenitic stainless hlau, qhov sib txawv ntawm lawv cov tshuaj muaj pes tsawg leeg, tshwj xeeb tshaj yog cov ntsiab lus molybdenum, ua rau muaj qhov sib txawv ntawm corrosion kuj. Stainless 317 feem ntau raug xaiv rau cov ntawv thov uas xav tau kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav tshuaj.
Qhov txawv ntawm AISI 316 thiab AISI 317 Stainless Steels:
1. Tshuaj muaj pes tsawg leeg:
AISI 316 stainless hlau (UNS S31600):
Chromium (Cr): 16-18%
Nickel (Ni): 10-14%
Molybdenum (Mo): 2-3%
Lwm cov ntsiab lus: Carbon (C), Silicon (Si), Manganese (Mn), Phosphorus (P), Sulfur (S)
AISI 317 stainless hlau (UNS S31700):
Chromium (Cr): 18-20%
Nickel (Ni): 11-15%
Molybdenum (Mo): 3-4%
Lwm cov ntsiab lus: Carbon (C), Silicon (Si), Manganese (Mn), Phosphorus (P), Sulfur (S)
Ua ntej, qib 317 stainless hlau muaj cov ntsiab lus siab dua me ntsis molybdenum piv rau qib 316 stainless hlau. Cov ntsiab lus molybdenum ntxiv nyob rau hauv TP317 pab txhim khu kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj lom neeg nruj dua.
Thib ob, AISI 317 muaj cov ntsiab lus nickel ntau dua li AISI 316. Nickel txhim khu kev tiv thaiv corrosion thiab pab ua kom lub zog thiab ductility ntawm cov khoom.
2. Corrosion Resistance:
AISI 317 UNS S31700feem ntau pom zoo corrosion kuj duaAISI 316 UNS S31600, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride. Cov ntsiab lus molybdenum siab dua hauv Alloy 317 muab kev txhim kho rau pitting thiab crevice corrosion.
3. Kev siv:
1.4401 AISI 316yog dav siv nyob rau hauv ntau yam kev siv, xws li marine ib puag ncig, tshuaj ua, thiab cov khoom siv kho mob. Nws muaj kev tiv thaiv corrosion zoo thiab raug nqi zoo.
1.4449 AISI 317feem ntau yog xaiv rau cov ntawv thov uas yuav tsum tau muaj kev tiv thaiv corrosion ntau dua, xws li hauv kev ua tshuaj lom neeg, cov ntaub so ntswg thiab cov ntawv lag luam, thiab ib puag ncig nrog cov tshuaj chloride siab.
4. Thaum tshav kub kub Resistance:
Ob leegAlloy 316 thiab 317muab cov cua sov zoo. Txawm li cas los xij, ntau dua molybdenum thiab nickel cov ntsiab lus hauvAISI stainless hlau 317tuaj yeem muab kev ua tau zoo me ntsis hauv cov ntawv thov kub.
5. Weldability:
Ob leeg alloys s31600 thiab s31700 yog feem ntau weldable siv cov txheej txheem vuam. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum ua raws li kev siv vuam kom zoo kom muaj kev tiv thaiv corrosion ntawm cov ntaub ntawv.
6. Tus nqi
Hais txog tus nqi, Qib316feem ntau tsis tshua kim dua317, uas tuaj yeem ua rau nws qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas tus nqi yog qhov tseem ceeb ntawm kev tsav tsheb. Txawm li cas los xij, rau cov ntawv thov uas muaj kev tiv thaiv corrosion, lub zog, thiab tawv yog qhov kev txhawj xeeb tseem ceeb, ss 317 yuav yog qhov kev xaiv zoo dua.
7. Cov neeg muab khoom
Peb lub tuam txhab yog ib tug kws tshaj lij thiab txhim khu kev qha ib-nres kev pab cuam chaw tsim tshuaj paus, tsum thiab exporter. Peb tuaj yeem muab 316 thiab317 stainless hlau ntawv, phaj, kav, raj, flanges thiab fittings, thiab lwm yam. Hu rau peb kom paub ntau ntxiv thiab hais lus dawb!
