1. Cov tsev neeg thiab cov muaj pes tsawg leeg
Tsis zoo: Tsev neeg ntawm Nickel-based superalloys, nrog npib tsib xee ua thawj lub caij (feem ntau 50-75% ni). Lawv kuj muaj cov chromium siab (14-23% cr Cov ntsiab lus hlau yog tsawg (feem ntau<10%, often <5%).
316L: Ib qho kev txo cov roj carbon aus roj carbon monustenic stainless hlau, ib feem ntawm cov tsev neeg hlau-raws li tsev neeg (hlau yog thawj lub caij, ~ 65-70% FE). Nws cov khoom tseem ceeb suav nrog 16-18% cr, 10-14% ni, 2-3% molybdenum (rau chloride tsis kam), thiab<0.03% carbon (the "L" denotes low carbon to reduce sensitization).
2. Corrosion Kuj
Inconel muaj kev tiv thaiv cov tshuaj zoo tshaj plaws rau kev txhoj puab heev (piv txwv li cov kua qaub muaj zog, alkalis, thiab oxidizing cov neeg sawv cev) vim nws cov ntsiab lus nickel siab. Nws txawj nyob hauv ib puag ncig xws li sulfuric acid, hydrochloric acid (hauv kev tswj cov kev mob), thiab qhov siab-kub curefosive gases.
316L muaj kev tiv thaiv corrosives, xws li dej hiav txwv, thiab cov organic acids (piv txwv li cov kua qaub) lossis huab cua kub.
Inconel (piv txwv li, Inconel 625 lossis 718) Outperforms 316L hauv chloride ib puag ncig, raws li nws siab dua molybdenum thiab qib nickel inhibit pitting thiab crevice corrosion.
316L Tsis kam Chloride Corrosion zoo dua li cov qauv stainless hlau (xws li muaj 304) tab sis tseem tuaj yeem raug kev txom nyem, lossis cov pa taws kub (piv txwv li dej hiav txwv kub).
Inconel yog tsim los rau huab cua sov heev (txog li 1,100℃/ igs dolt
316lxtizes cuam tshuam ntau dua 800℃(1,472℃f), txwv nws siv hauv kev siv kub txuas ntxiv.
3. Cov Khoom Siv Kho Tshuab
Inconel alloys (piv txwv li, Inconel 718) muaj ntau dua lub zog (900-1,300 mpa) thiab tawm lub zog ntawm 500 thiab lees lub zog ntawm 200-250 mpa. Qhov no yog vim tsis muaj cai nag lossis daus - Hardening Txheej txheem (piv txwv li, 'lossis "theem tsim) uas txhim kho lub zog.
316l yog coo pawg tab sis muaj qis dua lub zog tag nrho, cia siab rau nws cov qauv Austenitic rau kev nruj.
Inconel khaws kev tshwj xeeb lub zog thiab cov neeg nkag ntawm cov kub (txog 1,000 txog 1,832 Qib F) vim nws cov khoom siv alloy (piv txwv li cov alloy 718 stabilizes tivthaiv 718 Qhov no ua rau nws zoo rau kev ntxhov siab, cov ntawv thov kub zoo li roj turbine tuaj.
316l poob lub zog sai sai saum 600℃(1,112℃f) thiab tsis haum rau kev thauj khoom kub siab.
4. Sib Nqus Cov Khoom Siv
Tsis zoo: Feem ntau cov qhab nia tsis yog kev sib nqus lossis tsis muaj zog sib nqus, raws li cov qauv npib tsib xee thiab alloy-niobium Austenic lossis super-Austenitic lossis Super-Austenitic lossis Super-Austenitic lossis Super-Austenitic lossis Super-Austenitic Phase.
316L: Austenitic stainless hlau zoo li 316L feem ntau tsis muaj kev sib nqus hauv lub xeev annealed, tab sis kev ua haujlwm txias (piv txwv li txias me ntsis magnetism vim tias kev tsim ntawm martensite.
5. Weldability
Tsis zoo: Weldable tab sis yuav tsum tau ua tib zoo tuav kom tsis txhob tawg. Kev kub kub kub-kub (piv txwv li, inconel 718) yog nquag tawg vim yog cov cua sov, yog li kev kho cua sov sov, thiab tom qab) feem ntau tsim nyog.
316L: Zoo heev Veldability, txawm tias tsis muaj pwht, vim nws cov ntsiab lus carbon qis (tiv thaiv carbide nag lossis uas ua rau muaj kev txhim kho corrosion). Nws yog dav siv nyob rau hauv welded qauv zoo li pipelines thiab tso tsheb hlau luam.
6. Tus nqi thiab muaj
Tsis zoo: Tseem ceeb tshaj plaws kim dua 316L vim nws cov ntsiab lus npib tsib xee thiab cov khoom siv uas muaj txiaj ntsig (npib tsib xee). Feem ntau nws tshwj tseg rau kev ua tau zoo, muaj kev kub siab, lossis cov kev siv corrosion.
316L: Ntau cov nqis peev muaj thiab dav, ua kom nws cov ntawv thov zoo rau kev tiv thaiv kev txhim kho dav dav uas tsis tas yuav muaj lub zog.
7. Kev thov
Tsis zoo: Siv nyob rau hauv Aerospace (Turbeet cov cheebtsam), cov leeg hluav taws xob (high-kub ua), thiab roj / roj (downhole cov cuab yeej hauv cov hmoov av corrosive).
316L: Nquag nyob rau hauv cov khoom siv marine, khoom noj ua tshuab, kev tso tsheb hlau luam, qhov twg yog corrosion tawm tsam ib puag ncig me me yog xav tau).
Inconel excels nyob rau hauv high-kub, thiab corrosion ib puag ncig, thaum 316L yog ib qho kev xaiv corrosion ntau yam nyob rau hauv cov xwm txheej corrosion.
