S31803 yeeb nkab tsum,tiv tauj pebkom tau txais kev tsocai dawb thiab qauv!
Lub npe "Duplex" yog hais txog nws dual -phase microstructure. S31803 yog engineered kom kwv yees li 50%ferritethiab 50%austenite.
- Ferritemuab lub zog tawm los siab thiab ua haujlwm rau kev ntxhov siab corrosion cracking (SCC).
- Austenitekom toughness thiab yooj yim ntawm fabrication.
Los ntawm kev sib txuas ob qho no, S31803 muab lub zog tawm los ze li ob npaug ntawm cov pa austenitic steels, tso cai rau cov phab ntsa nyias nyias thiab qhov hnyav hnyav hauv qhov loj - cov kav dej loj.

S31803 vs. S32205: Koj Xav Tau Qhov twg?
Thaum feem ntau siv interchangeably, muaj ib qho kev sib txawv.S32205yog qhov tseem ceeb ntawm "siab-kawg" version ntawm S31803.
S31803Nws muaj qhov dav dav rau Chromium thiab Molybdenum.
S32205nruj cov kab no mus rau sab sauv txwv kom lav qhov siab duaPREN(Pitting Resistance Tus lej sib npaug).
Cov mills niaj hnub no feem ntau tsim cov yeeb nkab "dual{0}} ntawv pov thawj" uas ua tau raws li ob qho qauv, ua kom muaj kev tiv thaiv corrosion ntau tshaj yam tsis tau nce nyiaj txiag.
Ntiaj teb no Applications thiab Geo-Targeted Utility
Qhov kev thov rauASTM A790 S31803 cov kav dejNws txawv ntawm thaj chaw, uas tau tsav los ntawm cov teeb meem ib puag ncig hauv zos:
- Ntug hiav txwv dej thiab Marine (Ntiaj teb):Siv nyob rau hauv seawater cooling systems thiab subsea pipelines qhov twg chloride pitting yog thawj hem.
- Roj & Roj (Texas / Aberdeen / Middle East):Zoo tagnrho rau "qaub" ib puag ncig uas muaj hydrogen sulfide thiab siab -siab flowlines.
- Chemical Processing (Lub teb chaws Yelemees / Is Nrias teb):Qhov tseem ceeb rau kev thauj cov organic thiab inorganic acids qhov twg cov qauv hlau yuav ntsib cov phab ntsa sai sai.
- Desalination (MENA Thaj Chaw):Cov ntsiab lus siab molybdenum yog qhov tseem ceeb rau kev tawm tsam cov brine txhoj puab heev hauv cov nroj tsuag rov qab osmosis.
Daim ntawv txheeb xyuas: Seamless vs. Welded
Thaum txiav txim S31803 kav, txoj kev tsim khoom tseem ceeb npaum li cov hlau:
Seamless S31803 Yeeb Nkab:Txaus siab rau siab - cov tshuab siab thiab cov ntawv thov dej hiav txwv tseem ceeb. Nws tshem tawm txoj kev pheej hmoo ntawm weld-seam corrosion.
Welded S31803 Yeeb Nkab:Tus nqi -kev daws teeb meem zoo rau cov kab loj - txoj kab uas hla hauv kev kho dej lossis kev txhawb nqa cov txheej txheem uas qhov kev xav tau siab qis dua.
Vim li cas thiaj xaiv S31803 tshaj Carbon Steel?
Thaum tus nqi them ua ntej ib tuj siab dua, lubtag nrho lifecycle tus nqiqis dua. Koj tshem tawm qhov xav tau ntawm cov txheej txheem kim kim, kev tiv thaiv cathodic, thiab kev saib xyuas tsis tu ncua.
