304L stainless hlaufeem ntau yog siv rau hnyav - ntsuas cov khoom lag luam, cov khoom siv tshuaj lom neeg, thiab cov khoom siv tsim kho uas yuav tsum tau siv vuam ntau.
304L lub luag haujlwm tseem ceeb yog tswj kev tiv thaiv corrosion nyob rau hauv "heat- cuam tshuam cheeb tsam" ntawm cov pob qij txha. Yog li ntawd, 304L dominates industries tshwj xeeb hauv kev ua tshuaj, khoom noj khoom haus thiab dej haus, kev kho dej, mining pom, thiab architectural lug.
Heavy Gauge Welded Industrial Thawv
304L yog qhov yuav tsum tau ua tshwj xeeb rau cov tso tsheb hlau luam loj, cov hlab ntsha siab, thiab cov boilers kom tsis txhob muaj kev sib txhuam ntawm kev sib tsoo ntawm vuam seams.
Hauv kev lag luam hnyav, peb feem ntau ua haujlwm nrog cov hlau phaj tuab dua 6 hli. Thaum koj welding ntu ntawm cov thickness no, cov hlau tseem kub rau lub sijhawm ntev. Nyob rau hauv tus qauv 304 steel, qhov kev kub ntxhov no ua rau chromium carbides tsim, depleting cov txheej txheem chromium nyob ze ntawm qhov vuam. Qhov no ua rau "intergranular corrosion," qhov twg thaj tsam weld rots tam sim ntawd thaum lub tank tas li ci.
304L tshem tawm qhov kev pheej hmoo no tag nrho. Vim tias cov ntsiab lus ntawm cov pa roj carbon tsawg, chromium carbides tsis tuaj yeem tsim, txawm tias thaum lub sij hawm ntev cua sov ntawm hnyav - ntsuas vuam. Yog li ntawd, yuav luag txhua qhov loj -scale industrial vat, boiler, los yog lub nkoj siab uas koj pom nyob rau hauv lub Hoobkas chaw yog fabricated los ntawm 304L kom ntseeg tau tias cov seams yog corrosion-resistant li lub hauv paus hlau.
Chemical thiab Petrochemical Processing Equipment
Cov hlau no yog siv rau cov kav dej, cov khoom siv hluav taws xob, thiab cov tso tsheb hlau luam uas siv cov tshuaj me me thiab cov organic acids.
Txawm hais tias muaj kev kub ntxhov hauv marine lossis chloride ib puag ncig feem ntau xav tau 316L kim dua (uas muaj molybdenum), 304L yog cov neeg ua haujlwm rau cov qauv tshuaj ib puag ncig. Nws muaj kev tiv thaiv zoo rau oxidizing acids, xws li nitric acid, uas yog siv ntau hauv cov chiv thiab cov khoom tawg. Hauv cov chaw no, mais ntawm cov kav dej thiab cov chaw ua liaj ua teb loj yog tsim los ntawm 304L.
Nws ua rau qhov sib npaug zoo tshaj plaws ntawm kev ua haujlwm thiab Tus Nqi Muag Khoom (COGS). Rau ib tus neeg saib xyuas cov nroj tsuag, siv 304L rau tsis yog -chloride chemical cia yog qhov kev txiav txim siab txog nyiaj txiag; nws muab cov tshuaj tsim nyog inertness yam tsis muaj tus nqi hwm ntawm ntau dua -nickel alloys. Yog hais tias cov txheej txheem tshuaj muaj xws li nitric acid los yog organic acids nyob rau hauv nruab nrab kub, 304L yog cov ntaub ntawv teev xaiv.
Khoom noj khoom haus thiab dej haus Manufacturing Infrastructure
304L yog tus qauv kev lag luam rau cov brewery tso tsheb hlau luam, cov tankers mis nyuj, thiab cov khoom noj khoom haus hoppers vim nws qhov chaw huv thiab huv.
Hauv kev lag luam zaub mov, qhov chaw tiav yog txhua yam. Cov kab mob zais hauv qhov microscopic pits thiab crevices . 304L yog siv ntawm no tsis yog rau nws cov weldability xwb tab sis kuj vim nws tuaj yeem polished kom huv si uas tiv thaiv kab mob colonization. Thaum lub brewery nruab ib lub 2,000-gallon fermentation tank, lawv siv 304L los xyuas kom meej tias cov welds yog du thiab tsis muaj corrosion.
Tsis tas li ntawd, cov hlau tsis yog -reactive; nws yuav tsis leach metallic flavors rau hauv acidic khoom xws li lws suav sauce, npias, los yog mis nyuj haus. Los ntawm cov silos loj heev tuav cov nplej mus rau pasteurization piping nyob rau hauv cov khoom noj siv mis nyuj, 304L ua kom tau raws li FDA thiab thoob ntiaj teb cov qauv kev nyab xeeb khoom noj khoom haus thaum tiv taus cov tshuaj hnyav, caustic siv nyob rau hauv txhua hnub "Clean-nyob rau hauv-Place" (CIP) kev huv huv.
Kev kho dej thiab kev tswj cov khib nyiab
Cov chaw dej hauv nroog cia siab rau 304L rau cov kav dej, baffles, thiab cov kav dej vim nws lub zog siab thiab ua haujlwm tsis tu ncua.
Cov nroj tsuag kho dej yog qhov hnyav ib puag ncig uas muaj cov av noo siab thiab tsis tu ncua submersion. Cov pa roj carbon steel yuav xeb tawm hauv lub hlis; plastics feem ntau tsis muaj qhov tsim nyog rigidity . 304L muab cov kev daws teeb meem. Nws yog siv los tsim cov rooj vag uas tswj cov dej ntws (weirs), cov ntxaij lim dej uas ntes cov khib nyiab, thiab cov kav dej aeration uas tso cov pa oxygen rau hauv cov dej khib nyiab. Lub npe "L" yog qhov tseem ceeb ntawm no vim tias cov txheej txheem nyuaj no yuav tsum tau siv vuam ntau thaum sib dhos.
Yog hais tias cov welds yuav corrode, cov qauv kev ncaj ncees ntawm cov dej tswj systems yuav ua tsis tau tejyam, ua rau muaj kev puas tsuaj los yog dej nyab . 304L ua kom lub neej kev pab cuam ntsuas nyob rau hauv lub xyoo caum es tsis yog ntau xyoo, txo cov kev siv nyiaj hauv nroog loj.
Architectural Moldings thiab Sab nrauv Trim
Architects qhia 304L rau lub tsev facades, tes tuav, thiab of the elevator interiors kom muaj kev zoo nkauj zoo nkauj nyob rau hauv siab - chaw tsheb.
Thaum feem ntau cuam tshuam nrog kev lag luam hnyav, 304L muaj qhov tseem ceeb hauv kev tsim kho. Txawm li cas los xij, nws siv ntawm no yog nuanced. Rau cov nroog hauv av (tawm ntawm ntug dej hiav txwv ntsev), 304L yog tus qauv rau sab nrauv cladding thiab qhov rais thav ntawv. Nws muab qhov niaj hnub, sleek aesthetic uas txhais tau tias niaj hnub skyscrapers.
Qib "L" tshwj xeeb tshaj yog rau cov khoom siv xws li cov kab hluav taws xob hnyav lossis kev cai -welded railings hauv khw malls thiab tshav dav hlau. Hauv cov chaw siab no - tsheb thauj neeg pej xeem, cov khoom siv yuav tsum tiv taus qhov cuam tshuam ntawm lub cev thiab lub sijhawm tu kom huv si.
304L muaj qhov nyuaj los tiv thaiv denting thiab kev ruaj ntseg tshuaj los tiv thaiv cov neeg ua haujlwm tu siv los ntawm cov neeg ua haujlwm saib xyuas, ua kom lub tsev zoo li tshiab kaum xyoo tom qab kev tsim kho.
Mining thiab Filtration Screens
Woven hlau ntaub thiab perforated daim hlau ua los ntawm 304L yog ib qho tseem ceeb rau sifting thiab pom nyob rau hauv mining ua hauj lwm vim abrasion kuj.
Hauv cov mining thiab quarrying sector, cov ntaub ntawv ntsib ob qho kev hem thawj: ntub corrosion thiab lub cev abrasion . 304L yog dav siv los tsim "wedge wire" cov ntxaij vab tshaus thiab cov ntaub lim dej. Cov ntxaij vab tshaus no txheeb cov pob zeb hnyav, thee, thiab cov ntxhia. Lub alloy ua hauj lwm hardens sai heev, txhais tau tias nws yuav nyuaj thiab check dua li nws yog cuam tshuam los ntawm pob zeb thiab khib nyiab.
Cov cuab yeej no, ua ke nrog nws qhov kev tiv thaiv corrosion, ua rau 304L zoo tagnrho rau "kev tshuaj ntsuam ntub dej" qhov twg dej yog txau rau cov ore kom cais nws. Cov hlau softer yuav hnav sai sai; tus qauv carbon steel yuav xeb thiab paug cov khoom. 304L ciaj sia lub cev pounding thaum tiv thaiv cov kua qaub mine dej feem ntau tam sim no nyob rau hauv ib puag ncig extraction.
Xaus
Yog tias koj qhov phiaj xwm cuam tshuam nrog vuam hlau tuab dua li ob peb millimeters, lossis yog tias koj tab tom tsim cov txheej txheem tsim kom siv tau ntau xyoo hauv cov khoom siv tshuaj, khoom noj, lossis dej ua haujlwm, 304L tsis yog ib qho kev xaiv xwb - nws yog qhov yuav tsum tau ua. Nws muaj ntau yam ntawm 300-series austenitic steels nrog rau kev lees paub ntxiv tias koj qhov project cov qauv seams yuav nyob twj ywm zoo li cov khoom siv nws tus kheej.
