** 1. Thaum twg siv cov yeeb nkab stainless hlau? **
Cov yeeb nkab stainless hlau yog siv hauv cov ntawv thov uas yuav tsum muaj kev sib xyaw ua ke, xeb kuj, thiab kev nyiam huv. Cov siv sib xws li suav nrog:
* ** Kiv dej thiab cov dej ntws: ** Rau cov dej roj uas muaj ntsev thiab kav dej hauv cov tuam tsev uas tsis kam yog qhov tseem ceeb.
* ** Kev noj khoom haus thiab dej haus ua: ** Kev nyiam huv yog qhov chaw tu thiab huv (huv). Nws tsis ua kom saj lossis corrode.
* ** Tshuaj lom neeg thiab petrochemical Industries: ** Txhawm rau thauj cov tshuaj, roj av, thiab cov kuab tshuaj.
* ** Kev kho mob thiab cov ntaub ntawv: ** Rau siab - purity roj thiab kua kab thiab cov ntawv thov huv si.
* ** Kev tsim kho vajtse: ** Rau tes ua haujlwm, teeb meem, thiab cov txheej txheem sib xyaw ua ke hauv kev hnyav lossis av nkos.
* ** COV ROJ THIAB GAS: ** RAU DESHOLE tubing thiab nyob rau hauv ib puag ncig nrog cov tshuaj siab hnoos loj.
* ** High {{- qhov kev thov kub thiab siab: ** xws li cov rhaub, kev hloov pauv kub, thiab superheaters.
** 2. Dab tsi yog qhov sib txawv ntawm 304 thiab 316 Stainless hlau? **
Lub ntsiab sib txawv yog qhov sib ntxiv ntawm ** Molybdenum **.
* ** ** 304 Stainless hlau ** Muaj chromium (18 {{{{}} 20%) thiab npib tsib (8-10.5%). Nws yog qhov zoo tagnrho txhua lub sijhawm stainless hlau nrog zoo corrosion tsis kam.
* ** 316 stainless hlau ** muaj cov ntawv sib xws zoo sib xws thiab cov ntsiab lus npib tsib xee tab sis kuj muaj ** 2-3% Molybdenum **. Qhov no ntxiv tau nce ntxiv nws txoj kev tiv thaiv kom corrosion, tshwj xeeb tshaj tawm tsam chlorides thiab lwm yam kev muaj cov kuab tshuaj muaj. Qhov no ua rau 316 zoo dua rau kev siv hauv cov av marine thiab hauv kev siv cov tshuaj lom neeg.
** 3. Dab tsi pheej yig, 304 lossis 316 stainless? **
** 304 Stainless hlau yog tus pheej yig dua ** tshaj 316. Vim li cas 316. Cov ntsiab lus tsib xee hauv 316 kuj yog feem ntau dua me ntsis, ntxiv rau nws tus nqi.
** 4. Qhov twg yog qhov zoo dua, 302 lossis 304 stainless hlau? **
** 304 Stainless hlau yog feem ntau suav hais tias yog qhov zoo dua ** rau cov ntawv thov feem ntau.
* ** 302 stainless ** muaj cov ntsiab lus roj carbon ntau dua (0.15% max) tshaj 304 (0.08% Max).
* ** ** 304 qhov qis dua cov ntsiab lus cov pa roj carbon ntxiv ** ua rau nws tsis tshua muaj tsawg dua rau cov chromium carbon carbides ntawm cov ciaj ciam av) thaum lub sij hawm vuam, uas tuaj yeem ua rau corrosion. Qhov no ua rau 304 qhov kev xaiv rau kev siv Welded thiab muab lub npe "18/8" stainless.
* 302 yog tseem siv rau tsis yog - Welded cov khoom xws li springs thiab xas uas siab dua thiab corrosion {{}} Resistant qib.
** 5. Kuv yuav paub tau li cas yog tias kuv SS yog 304 lossis 316? **
Nws yog qhov nyuaj heev los qhia lawv sib nrug los ntawm kev pom lossis kov raws li lawv saib zoo ib yam. Koj yuav tsum tau ua ib qho kev xeem:
* ** Txoj kev zoo tshaj plaws: XRF Analyzer. ** Qhov no yog cov twj paj nruag sib txuas uas muaj tseeb qhia txog cov hlau uas muaj pes tsawg leeg. Nws yog tus kws tshaj lij, tsis - tus qauv kev puas tsuaj.
* ** Cov khoom siv tshuaj ntsuam xyuas cov khoom siv tshuaj: ** Koj tuaj yeem siv cov khoom siv ntsuas ntsuas uas pom Molybdenum. Ib qho kev sim ntawm kev ntsuas tau siv rau cov hlau. Yog hais tias tus poob tig ** brownish - liab lossis liab dawb **, nws qhia tau tias cov hlau yog 316), nws qhia tias qhov tsis muaj molybdenum.
* ** Qhov kev xeem sib txawv (tsis pom zoo): ** Qhov no yog qhov tsis muaj peev xwm rau kev sib txawv ntawm 304 thiab 316 thiab yuav tsum muaj tus kws tshaj lij. Lub txim ntws tau zoo heev.
