AISI 904L zitsulo zosapanga dzimbiri kapena AISI 904L (WNR1.4539) ASTM A 249, N08904, X1NiCrMoCu25-20-5 ndi alloy apamwamba austenitic zitsulo zosapanga dzimbiri. Poyerekeza ndi 316L, SS904L ili ndi mpweya wocheperako (C), wokhala ndi chromium (Cr) wokwera kwambiri, komanso pafupifupi kuwirikiza kwa faifi tambala (Ni) ndi molybdenum (Mo) wa 316L, zomwe zimapatsa kutentha kwambiri...
904L (N08904,, 14539) chitsulo chosapanga dzimbiri cha austenitic chili ndi 19.0-21.0% chromium, 24.0-26.0% nickel, ndi 4.5% molybdenum. 904L super austenitic chitsulo chosapanga dzimbiri ndi chitsulo chochepa cha carbon, nickel high, molybdenum austenitic stainless acid-resistant steel, chomwe ndi chuma chaumwini chomwe chinayambitsidwa kuchokera ku kampani ya ku France ya H·S. Ili ndi mphamvu yabwino yosinthira-passivation, kukana kwa dzimbiri, kukana bwino kwa dzimbiri mumafuta osatulutsa okosijeni monga sulfuric acid, acetic acid, formic acid, phosphoric acid, kukana bwino kwa ma pitting mu media media ya chloride ion, komanso kukhazikika bwino kwa dzimbiri komanso kukana kupsinjika. Ndi oyenera ndende zosiyanasiyana sulfuric asidi pansi pa 70 ° C, ndipo ali ndi dzimbiri kukana mu asidi acetic wa ndende iliyonse ndi kutentha kulikonse pansi pa kupsyinjika yachibadwa, ndi asidi osakaniza formic acid ndi asidi asidi.
AISI 904L chitsulo chosapanga dzimbiri ndi alloy austenitic chitsulo chosapanga dzimbiri chokhala ndi mpweya wochepa kwambiri. Kuphatikiza kwa chromium yapamwamba, faifi tambala, molybdenum ndi mkuwa kumapereka chitsulo chabwino kukana dzimbiri. Kuwonjezera mkuwa kumapangitsa kukhala ndi asidi amphamvu kukana, akhoza kukana zosiyanasiyana organic ndi inorganic zidulo, makamaka kloridi mpata dzimbiri ndi nkhawa dzimbiri akulimbana, si kophweka dzimbiri mawanga ndi ming'alu, ndipo ali amphamvu pitting kukana. AISI 904L ili ndi kukana bwino kwa dzimbiri mu dilute sulfuric acid. Aloyi ndi chitsulo choyenera kusungunula sulfuric acid wamphamvu zowononga sing'anga. Imalimbananso ndi madzi a m'nyanja, imakhala ndi machinability ndi weldability, ndipo imagwiritsidwa ntchito kwambiri pomanga, mankhwala, zamankhwala ndi mafakitale ena.
AISI 904L chitsulo chosapanga dzimbiri chimagwiritsidwa ntchito mowirikiza mu makina amafuta ndi zida za petrochemical; sulfuric acid yosungirako ndi zipangizo zoyendera, monga osinthanitsa kutentha; flue gasi desulfurization zida mu zomera mphamvu, monga nsanja, zitoliro, zotsekera, zigawo zikuluzikulu mkati, sprayers, mafani, etc. mu machitidwe mankhwala asidi organic; zipangizo zoyeretsera madzi a m’nyanja, monga zosinthira kutentha kwa madzi a m’nyanja; zida zamakampani opanga mapepala, sulfuric acid, zida za nitric acid; zida zamagetsi, zotengera zokakamiza, zida za chakudya monga kupanga asidi ndi mafakitale opanga mankhwala.

-Zida zochizira madzi a m'nyanja, zosinthira kutentha kwamadzi am'nyanja, zida zamakampani opanga mapepala, sulfuric acid, zida za nitric acid, kupanga asidi, makampani opanga mankhwala ndi zida zina zamankhwala, zotengera zokakamiza, zida za chakudya.
Zomwe zimapangidwa ndi Womic Steel: mapaipi achitsulo osapanga dzimbiri a 904L akupezeka mumitundu yosiyanasiyana yopanga mu mzere wa Womic Steel Production, kuphatikiza mapaipi opanda msoko ndi mapaipi owotcherera. Kuzungulira kwakunja kwa mapaipi opanda msoko nthawi zambiri kumachokera ku 3 mpaka 720 mm (φ1 mpaka 1200 mm), ndi makulidwe a khoma la 0,4 mpaka 14 mm; m'mimba mwake akunja mipope welded zambiri ranges kuchokera 6 mpaka 508 mm, ndi khoma makulidwe a 0,3 kuti 15.0 mm.
Kuphatikiza apo, palinso mawonekedwe osiyanasiyana monga mapaipi apakati ndi mapaipi amakona anayi, mipiringidzo yachitsulo, mbale, zomangira zokhala ndi zitsulo zosapanga dzimbiri zomwe mungasankhe mu Womic Steel.
