AISI 904L stainless hlau los yog AISI 904L (WNR1.4539) ASTM A 249, N08904, X1NiCrMoCu25-20-5 yog lub siab alloy austenitic stainless hlau. Piv nrog rau 316L, SS904L muaj cov ntsiab lus qis dua (C) cov ntsiab lus, siab dua chromium (Cr) cov ntsiab lus, thiab li ob npaug ntawm cov npib tsib xee (Ni) thiab molybdenum (Mo) cov ntsiab lus ntawm 316L, muab nws kub dua ...
904L (N08904, 14539) super austenitic stainless hlau muaj 19.0-21.0% chromium, 24.0-26.0% nickel, thiab 4.5% molybdenum. 904L super austenitic stainless hlau yog cov pa roj carbon tsawg, siab nickel, molybdenum austenitic stainless acid-resistant steel, uas yog cov khoom siv tswv yim los ntawm Fabkis H·S tuam txhab. Nws muaj peev xwm ua kom zoo-passivation transformation muaj peev xwm, zoo heev corrosion kuj, zoo corrosion kuj nyob rau hauv non-oxidizing acids xws li sulfuric acid, acetic acid, formic acid, phosphoric acid, zoo pitting kuj nyob rau hauv nruab nrab chloride ion media, thiab zoo crevice corrosion thiab kev nyuaj siab. corrosion kuj. Nws yog haum rau ntau yam ntawm sulfuric acid hauv qab 70 ° C, thiab muaj corrosion kuj zoo nyob rau hauv acetic acid ntawm tej concentration thiab tej kub nyob rau hauv ib txwm siab, thiab sib tov acid ntawm formic acid thiab acetic acid.
AISI 904L stainless hlau yog high-alloy austenitic stainless hlau uas tsis tshua muaj carbon cov ntsiab lus. Kev sib xyaw ua ke ntawm high chromium, npib tsib xee, molybdenum thiab tooj liab muab cov hlau zoo zoo corrosion kuj. Qhov sib ntxiv ntawm tooj liab ua rau nws muaj zog acid tsis kam, tuaj yeem tiv taus ntau yam organic thiab inorganic acids, tshwj xeeb tshaj yog cov tshuaj chloride crevice corrosion thiab kev nyuaj siab corrosion cracking, tsis yooj yim kom muaj corrosion thiab tawg, thiab muaj zog pitting kuj. AISI 904L muaj corrosion kuj zoo nyob rau hauv dilute sulfuric acid. Lub alloy yog ib tug hlau haum rau dilute sulfuric acid muaj zog corrosive nruab nrab. Nws kuj yog resistant rau seawater, muaj zoo machinability thiab weldability, thiab yog dav siv nyob rau hauv kev tsim kho, tshuaj, kho mob thiab lwm yam lag luam.
AISI 904L stainless hlau feem ntau yog siv rau hauv reactors hauv roj av thiab petrochemical khoom; sulfuric acid cia thiab cov khoom siv thauj mus los, xws li cov khoom siv hluav taws xob; flue gas desulfurization khoom nyob rau hauv lub hwj chim nroj tsuag, xws li yees, flues, shutters, internal Cheebtsam, sprayers, kiv cua, thiab lwm yam nyob rau hauv cov organic acid kev kho mob systems; Cov khoom siv kho dej hiav txwv, xws li seawater heat exchangers; cov khoom siv kev lag luam ntawv, sulfuric acid, cov khoom siv nitric acid; Cov khoom siv tshuaj lom neeg, cov hlab ntsha siab, cov khoom siv khoom noj xws li acid ua thiab kev lag luam tshuaj.
