Chitsulo chosapanga dzimbiri cha Austenitic

Chitsulo chosapanga dzimbiri cha Austenitic chimatanthawuza chitsulo chosapanga dzimbiri chokhala ndi mawonekedwe austenitic kutentha kutentha. Chitsulo chosapanga dzimbiri cha Austenitic ndi chimodzi mwamagulu asanu azitsulo zosapanga dzimbiri ndi mawonekedwe a crystalline (pamodzi ndi ferritic, martensitic, duplex ndi mpweya wouma). Pamene chitsulo chili pafupifupi 18% Cr, 8% -25% Ni, ndi pafupifupi 0.1% C, ali khola austenite dongosolo. Chitsulo chosapanga dzimbiri cha Austenitic chromium-nickel chimaphatikizapo chitsulo chodziwika bwino cha 18Cr-8Ni ndi chitsulo chapamwamba cha Cr-Ni chopangidwa powonjezera Cr ndi Ni zomwe zili ndikuwonjezera Mo, Cu, Si, Nb, Ti ndi zinthu zina pamaziko awa. Chitsulo chosapanga dzimbiri cha Austenitic sichikhala ndi maginito ndipo chimakhala cholimba kwambiri komanso pulasitiki, koma mphamvu zake ndizochepa, ndipo sizingatheke kulimbitsa kupyolera mu kusintha kwa gawo. Ikhoza kulimbikitsidwa ndi ntchito yozizira. Ngati zinthu monga S, Ca, Se, Te ziwonjezedwa, zimakhala ndi machinability.

Auto Parts Cast ndi Investment Casting ya Autenitic Stainless Steel

 

Chitsulo chosapanga dzimbiri cha Austenitic chimatha kupanganso ma castings, nthawi zambiri ndindondomeko yopangira ndalama. Pofuna kupititsa patsogolo kusungunuka kwachitsulo chosungunula ndi kupititsa patsogolo ntchito yoponyera, ma alloy apangidwe a zitsulo zotayidwa ayenera kusinthidwa powonjezera zitsulo za silicon, kukulitsa kuchuluka kwa chromium ndi faifi tambala, ndikuwonjezera malire apamwamba a sulfure.

Chitsulo chosapanga dzimbiri cha Austenitic chiyenera kukhala cholimba-chothetsera chisanayambe kugwiritsidwa ntchito, kuti chiwonjezere njira yolimba yazitsulo zosiyanasiyana monga carbides muzitsulo za austenite masanjidwewo, komanso homogenizing kapangidwe kake ndikuchotsa kupsinjika, kuonetsetsa kuti kukana kwa dzimbiri ndi makina katundu. Njira yoyenera yothetsera vutoli ndi kuziziritsa kwamadzi mutatha kutentha pa 1050 ~ 1150 ℃ (zigawo zopyapyala zimathanso kuziziritsidwa ndi mpweya). The njira yothetsera kutentha zimadalira mlingo wa aloyi wa zitsulo: Molybdenum-free kapena otsika-molybdenum zitsulo magiredi ayenera kukhala otsika (≤1100 ℃), ndi apamwamba aloyi sukulu monga 00Cr20Ni18Mo-6CuN, 00Cr25Ni22Mo2N, etc. ayenera kukhala apamwamba ( 1080-1150) ℃).

Chitsulo chachitsulo chosapanga dzimbiri cha Austenitic 304, chomwe chimati chimabweretsa kukana dzimbiri ndi dzimbiri, ndipo chimakhala ndi pulasitiki yabwino kwambiri komanso yolimba, yomwe ndi yabwino kupondaponda komanso kupanga. Ndi kachulukidwe ka 7.93g / cm3, 304 chitsulo chosapanga dzimbiri ndi chitsulo chosapanga dzimbiri chodziwika bwino, chomwe chimatchedwanso 18/8 chitsulo chosapanga dzimbiri pamakampani. Zogulitsa zake zachitsulo zimagonjetsedwa ndi kutentha kwakukulu ndipo zimakhala ndi zinthu zabwino zowonongeka, choncho zimagwiritsidwa ntchito kwambiri m'mafakitale ndi mafakitale okongoletsera mipando ndi mafakitale a zakudya ndi zamankhwala.
