904L|N08904 Aloyi Chitsulo chachitsulo
Kufotokozera Kwachidule:
904L austenitic zitsulo zosapanga dzimbiri ndi za low-carbon, high nickel, molybdenum austenitic chitsulo chosapanga dzimbiri chokhala ndi acid kukana.904L chitsulo chosapanga dzimbiri cha austenitic chili ndi kuthekera kosintha kosinthika, kukana kwa dzimbiri, kukana kwa dzimbiri mu ma acid omwe si oxidizing monga sulfuric acid, acetic acid, formic acid, ndi phosphoric acid, kukana bwino kuyika dzimbiri mu media media chloride ion, ndi zabwino. kukana dzimbiri kung'amba ndi kupsinjika maganizo.Oyenera ndende zosiyanasiyana za asidi sulfuric m'munsimu 70 ℃, ali zabwino dzimbiri kukana ndende iliyonse ndi kutentha kwa asidi asidi ndi chisakanizo cha asidi formic ndi asidi acetic pansi kuthamanga yachibadwa.
904L ndi mpweya wochepa kwambiri, high alloying austenitic zosapanga dzimbiri zitsulo zopangidwira malo owopsa owononga.Ili ndi kukana kwa dzimbiri bwino kuposa 316L ndi 317L, pomwe ikulinganiza mtengo ndi magwiridwe antchito, ndipo imakhala yotsika mtengo kwambiri.Chifukwa chowonjezera mkuwa wa 1.5%, imakhala ndi kukana kwa dzimbiri pochepetsa ma acid monga sulfuric acid ndi phosphoric acid.Lilinso ndi dzimbiri bwino kukana dzimbiri kupsinjika maganizo, pitting dzimbiri, ndi mpata dzimbiri chifukwa cha chloride ayoni, ndipo kukana bwino dzimbiri intergranular.Mu sulfuric acid koyera ndi ndende osiyanasiyana 0-98%, kutentha ntchito 904L akhoza kufika madigiri 40 Celsius.Mu asidi wa phosphoric wokhala ndi ndende ya 0-85%, kukana kwake kwa dzimbiri ndikwabwino kwambiri.Zonyansa zimakhudza kwambiri kukana kwa dzimbiri kwa mafakitale a phosphoric acid opangidwa ndiukadaulo wonyowa.Mwa mitundu yonse ya asidi phosphoric, 904L ali bwino dzimbiri kukana kuposa zitsulo zosapanga dzimbiri wamba.Mu acid oxidizing nitric acid, 904L imakhala ndi kukana kwa dzimbiri kochepa poyerekeza ndi magiredi apamwamba azitsulo opanda molybdenum.Mu hydrochloric acid, kugwiritsa ntchito 904L kumangokhala kutsika kwa 1-2%.Mkati mwa ndende iyi.Kukana kwa dzimbiri kwa 904L kuli bwino kuposa chitsulo chosapanga dzimbiri wamba.Chitsulo cha 904L chimakhala ndi kukana kwakukulu kwa dzimbiri.Kukana kwake kwa dzimbiri mu mng'alu mu njira ya chloride.Mphamvu ndi yabwino kwambiri.Nickel yochuluka ya 904L imachepetsa kuchuluka kwa dzimbiri m'maenje ndi m'ming'alu.Chitsulo chosapanga dzimbiri chodziwika bwino cha austenitic chikhoza kukhudzidwa ndi kupsinjika kwa dzimbiri m'malo okhala ndi chloride pa kutentha kopitilira 60 digiri Celsius.Powonjezera kuchuluka kwa nickel muzitsulo zosapanga dzimbiri, kulimbikitsana uku kumatha kuchepetsedwa.Chifukwa cha kuchuluka kwake kwa faifi tambala, 904L imawonetsa kukana kwambiri kupsinjika kwa corrosion kung'ambika mu njira za chloride, mayankho okhazikika a hydroxide, ndi malo okhala ndi hydrogen sulfide.
Petroleum ndi petrochemical zida, monga reactors mu zida petrochemical, yosungirako ndi mayendedwe zida sulfuric acid, monga exchangers kutentha, mphamvu zomera flue mpweya desulfurization zipangizo, makamaka ntchito nsanja thupi, chitoliro, mapanelo zitseko, zigawo zamkati, kachitidwe kutsitsi, etc. wa mayamwidwe nsanja, scrubbers ndi mafani mu machitidwe organic asidi mankhwala, zipangizo mankhwala madzi a m'nyanja, madzi a m'nyanja kutentha exchangers, papermaking zipangizo mafakitale, asidi sulfuric ndi nitric asidi zida, kupanga asidi, etc Makampani mankhwala ndi zida mankhwala, zotengera kuthamanga, zipangizo chakudya. , mafakitale opanga mankhwala: centrifuges, reactors, etc., zomera chakudya: soya msuzi akasinja, vinyo kuphika, akasinja mchere, zipangizo ndi mavalidwe, 904L ndi lofananira zitsulo kalasi kuti kuchepetsa sulfuric acid wamphamvu zikuwononga sing'anga.
Mbale, Mzere, bala, waya, forging, yosalala ndodo, kuwotcherera zinthu, flange, etc., akhoza kukonzedwa molingana ndi kujambula
