SS904L AISI 904L Stainless Steel (UNS N08904)

Kufotokozera Kwachidule:

UNS NO8904, yomwe imadziwika kuti 904L, ndi chitsulo chochepa cha carbon high alloy austenitic zosapanga dzimbiri chomwe chimagwiritsidwa ntchito kwambiri m'malo omwe zinthu zowonongeka za AISI 316L ndi AISI 317L sizokwanira. 904L imapereka kukana kwa chloride kupsinjika kwa dzimbiri, kukana kutsekereza, komanso kukana kwa dzimbiri kuposa 316L ndi 317L molybdenum zitsulo zosapanga dzimbiri.

AISI 904L chitsulo chosapanga dzimbiri (UNS N08904) ndi aloyi wapamwamba austenitic chitsulo chosapanga dzimbiri. Poyerekeza ndi 316L, SS904L ili ndi mpweya wocheperako (C), wokwera wa chromium (Cr), komanso pafupifupi kuwirikiza ka nickel (Ni) ndi molybdenum (Mo)316l ndi, zomwe zimapangitsa kuti zikhale ndi kutentha kwakukulu kwa okosijeni kukana, kukana kwa pitting, ndi kukana kuchepetsa asidi (mwachitsanzo, sulfuric acid). Nayitrojeni (N) imatha kuchepetsa kuchuluka kwa mpweya wa chromium carbide, potero imachepetsa kukhudzika kwa chidwi, imathandiziranso kukana kutsekeka ndi dzimbiri chifukwa cha ma chloride. Makamaka kuwonjezera kwake kwa mkuwa (Cu) kumapangitsa kuti zikhale zothandiza pamagulu onse a sulfuric acid.

Aloyi 904L imagwira ntchito bwino kuposa zitsulo zina zosapanga dzimbiri za austenitic chifukwa cha kuphatikizika kwakukulu kwa faifi tambala ndi molybdenum. Kalasiyi ndi yopanda maginito m'mikhalidwe yonse ndipo imakhala ndi mawonekedwe abwino komanso amawotcherera. Mapangidwe a austenitic amapatsanso girediyi kulimba kwambiri, ngakhale mpaka kutentha kwa cryogenic Zomwe zili mu chromium zimalimbikitsa ndikusunga filimu yokhazikika yomwe imateteza zinthuzo m'malo ambiri owononga. Palibe chiopsezo cha intercrystalline corrosion pakuzizira kapena kuwotcherera chifukwa cha kuchepa kwa mpweya. Kutentha kwake kwakukulu kwa ntchito ndi 450 ° C. Kalasi iyi ndiyothandiza kwambiri pakuwongolera ndi kugwiritsa ntchito machubu pomwe 316 ndi 317L sizoyenera.

Aloyi 904L poyambirira idapangidwa kuti ipirire malo okhala ndi dilute sulfuric acid. Amaperekanso kukana kwabwino kwa ma inorganic acid monga otentha phosphoric acid komanso ma organic acid ambiri.

Alloy 904L imawotcherera mosavuta ndikukonzedwa ndi njira zopangira masitolo.

Chitsulo chosapanga dzimbiri cha 904L (SS904L) chimagwiritsidwa ntchito mumafuta, mankhwala, feteleza, nsanja zachitukuko zam'madzi, akasinja, mapaipi ndi machubu ndi osinthanitsa kutentha. Rolex ndi opanga mawotchi ena amagwiritsanso ntchito kupanga mawotchi
