S32304 Khoom Khoom
UNS S32304 belongs rau Asmeskas tus qauv dual-theem steel, tus qauv siv: ASTM A240 / A270M-2017
UNS S32304 alloy yog duplex stainless hlau uas muaj 23% chromium thiab 4% npib tsib xee.Cov khoom tiv thaiv corrosion ntawm 2304 alloy zoo ib yam li 316L.Tsis tas li ntawd, nws cov khoom siv kho tshuab, lub zog tawm los, yog ob npaug ntawm 304L / 316L austenitic qib.Cov yam ntxwv no ua rau cov neeg tsim qauv txo qhov hnyav ntawm cov khoom thaum tsim cov khoom, tshwj xeeb tshaj yog cov hlab ntsha siab.
Qhov no alloy yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv -50 ° C / + 300 ° C (-58 ° F / 572 ° F) kub ntau yam.Cov cua kub qis dua tuaj yeem siv tau raws li kev txwv nruj me ntsis (tshwj xeeb tshaj yog rau cov qauv welded).Piv nrog rau 304 thiab 316 austenite, 2304 alloy muaj zog tiv thaiv corrosion vim nws ob-theem microstructure, qis nickel cov ntsiab lus thiab cov ntsiab lus chromium ntau dua.
S32304 Cov Khoom Siv Cov Khoom Siv
2304 duplex stainless hlau muaj cov cuab yeej zoo thiab lub cev muaj zog, tiv thaiv kev ntxhov siab corrosion thiab lwm yam corrosion thiab zoo weldability, ua rau nws muaj peev xwm hloov austenitic stainless hlau xws li 304, 304L, 316, 316L thiab lwm yam.Nws tuaj yeem siv rau hauv kev tsim cov khoom siv amine rov qab, cov khoom siv fermentation rau hydrocarbons, thiab lwm yam. Tsis tas li ntawd, nws kuj tseem siv tau los ua cov khoom siv hluav taws xob hauv kev tsim khoom, cov tshuab nqus tsev preheaters hauv kev lag luam pulp thiab ntawv, thiab tsheb ciav hlau lub rooj zaum hauv cov av ntub. tshav kub thiab thaj chaw sab nraud.
1.Feem ntau cov teb siv los ntawm 304 thiab 316
2.Pulp thiab ntawv kev lag luam (chips, nti cia tso tsheb hlau luam, dub los yog dawb kua tso tsheb hlau luam, sorters)
3. Caustic kua, organic acid (anti-SCC)
4. kev lag luam zaub mov
5. Lub nkoj siab (kom txo qhov hnyav)
6. Mining (abrasive/corrosion)
