ASTM A213 Stainless Hlau 321 S32100 kav dejyog pom tau dav rau lawv cov kev tiv thaiv corrosion tsis kam, uas ua rau lawv xaiv zoo tshaj plaws rau ntau yam kev siv thiab kev ua haujlwm siab. Cov xeeb ceem no feem ntau ntawm ob qho tseem ceeb: oxidation tsis kam ntawm nce kub thiab tiv taus intergranular corrosion, tshwj xeeb tshaj yog tom qab vuam.
Qhov tseem ceeb ntawmASTM A312 TP 321 1. 4541 kav dej
1. Oxidation Kuj
Stainless Steel 321 pipes exhibit excellent resistance to oxidation and scaling in high-temperature environments, maintaining structural integrity and performance at temperatures up to 900 degree (1652 degree F). Qhov no yog vim kev tsim cov txheej txheem khib nyiab oxide ruaj khov rau saum npoo av, uas ua raws li kev tiv thaiv kev tiv thaiv kev tiv thaiv ib puag ncig thiab tshuaj lom neeg.
Vim li cas cov teeb meem: nyob rau hauv cov chaw kub, oxidation tuaj yeem ua rau cov khoom tsis ua haujlwm, kev ua tiav.ASME SA213 Tp321 Seamless kav'Muaj peev xwm tiv thaiv cov mob no ua kom muaj kev vam meej thiab kev ntseeg tau.
2. Intergranular corrosion tsis kam
Qhov kev suav ntawm titanium nyob rau hauv stainless hlau 321 tiv thaiv kev tsim ntawm chromium carbides ntawm cov ciaj ciam av thaum lub zog kub. Cov carbides no, yog tias tsim, yuav deprete chromium los ntawm cov hlau matrix, rov ua nws raug rau intergranular corrosion.
Vim li cas cov teeb meem: intergranular corrosion feem ntau tshwm sim nyob rau hauv cov hlau stainless nthuav tawm tshwj xeeb rau cov mob tshwj xeeb, tshwj xeeb yog tom qab vuam.Werkstoff NR. 1.4541 yeeb nkabSunanium ruaj khov tshem tawm txoj kev pheej hmoo no, kom ntseeg tau cov khoom tseem muaj zog thiab corrosion-resistant txawm tias muaj ib puag ncig nyuaj.
Cov ntawv thov siv tus nqi zog cov kev zoo no
Qhov tshwj xeeb corrosion resistance yam ntxwv ntawm 321 stainless hlau kav ua rau lawv tsis tseem ceeb hauv ntau yam kev lag luam. Hauv qab no yog cov sectors tseem ceeb uas cov txiaj ntsig zoo ua tau lub luag haujlwm tseem ceeb:
1. AERPOSPACE thiab AViation
Daim ntawv thov: Cheebtsam zoo li kev tso ua manifolds, turbine tshuab, thiab kev hloov pauv kub.
Vim li cas: cov khoom siv tiv thaiv cov high-kub oxidation thiab cua sov ua tsis muaj kev ntseeg siab, tseem ceeb rau kev siv hluav taws xob.
2. Tshuaj lom neeg
Daim Ntawv Thov: Luam rau Tshuaj Txhuam Cov Tshuaj Txhuam Hniav, Cov Khoom Siv Hluav Taws Xob, thiab Cov Nkoj Cov Hlab.
Vim li cas: cov tsis kam mus rau oxidation thiab intergranular corrosion uaUNR UNS UNRENSESS STEEL YEEB NKABQhov zoo tagnrho rau thauj cov tshuaj tiv thaiv corrosive thiab kev ua haujlwm nyob rau hauv qhov chaw kub-ib puag ncig.
3. Petrochemical thiab Refining
Daim Ntawv Thov: Piping Systems rau kev ua kom zoo dua, catalytic crackers, thiab nplaim taws.
Vim li cas: qhov kub-ua tsis kam ntawm cov kev txuas nrog cov txiaj ntsig zoo heev nyob rau hauv cov kab mob tsis zoo.
4. Lub zog tiam
Daim Ntawv Thov: Boiler Tubes, Superheaters, thiab Reheaters.
Vim li cas: Lub peev xwm tiv taus oxidation ntawm kev nce siab kub uaASTM A213 TP 321 kavQhov tseem ceeb hauv cov nroj tsuag thermal.
5. Automotive thiab Tsheb Thauj Mus Los
Daim Ntawv Thov: Tso Tshuab thiab Catalytic Conversers.
Yog vim li cas: muaj kub kub kub thiab oxidation resistance kom ntseeg tau ntev-ntev ntev kev ua tau zoo hauv cov khoom lag luam hauv tsheb.
6. Kev ua zaub mov noj thiab cov chaw muag tshuaj
Daim Ntawv Thov: Cua Sov Pauv Tubing, Chav rhaub, thiab thauj khoom muaj cov khoom noj-cov khoom noj.
Vim li cas: tus321 Uncut S32100 Seamless Yeeb NkabQhov muaj peev xwm los tswj kev huv si thiab tiv taus corrosion nyob rau hauv kub tsis hloov pauv yog qhov tseem ceeb hauv cov lag luam no.
7. Roj thiab roj
Daim ntawv thov: Offshore thiab onshore raj xa dej, kev pauv hluav taws xob, tshav kub kub, thiab cov khoom siv ua cua sov.
Vim li cas: tsis kam mus rau qhov kev kub siab thiab cov ntsiab lus ntawm hydrogen sulfide thiab dej hiav txwv.
8. Lub Sijhawm Ib puag ncig
Daim Ntawv Thov: Cov khoom siv khib nyiab pov tseg thiab cov kuab tshuaj kuab tswj cov pa hluav taws xob.
Yog vim li cas: cov oxidation kub tiv thaiv tsis tu ncua nyob rau hauv theem siab nyob hauv kev ua phem nyob rau hauv theem siab ib puag ncig.
