Mapepala achitsulo chosapanga dzimbiri ali ndi pamwamba posalala, pulasitiki wambiri, kulimba, komanso mphamvu zamakanika, ndipo amalimbana ndi dzimbiri kuchokera ku mpweya wa acidic ndi alkaline, mayankho, ndi zinthu zina. Ndi chitsulo chosakanikirana chomwe sichichita dzimbiri mosavuta, koma sichimalimbana ndi dzimbiri konse. Mapepala achitsulo chosapanga dzimbiri amatanthauza mapepala achitsulo omwe amalimbana ndi dzimbiri kuchokera ku zinthu zofooka monga mlengalenga, nthunzi, ndi madzi, pomwe mapepala achitsulo osagwira asidi amatanthauza mapepala achitsulo omwe amalimbana ndi dzimbiri kuchokera ku zinthu zowononga monga ma acid, alkali, ndi mchere.
Mapepala achitsulo chosapanga dzimbiri amabwera m'magawo osiyanasiyana, ndipo mndandanda wofunika kwambiri pamalonda kuphatikizapo austenitic, ferritic, duplex, ndi martensitic. Mtundu uliwonse uli ndi mawonekedwe apadera a makina komanso kukana dzimbiri, zomwe zimapangitsa kuti ukhale woyenera kugwiritsidwa ntchito mwanjira inayake.
Chitsulo Chosapanga Dziwe cha Austenitic (Mndandanda wa 300)
304/304L: Chitsulo chosapanga dzimbiri chogwiritsidwa ntchito nthawi zonse. Chimalimba bwino ndi dzimbiri, chimatha kupangika, komanso chimatha kusunthika.
316/316L: Ndi kuwonjezera 2-3% molybdenum, imakhala yolimba kwambiri ku ma chloride (madzi a m'nyanja, mchere wochotsa icing).
321: Ndi kuwonjezera titaniyamu wokhazikika, zimalepheretsa kukhudzidwa kwa kutentha panthawi yowotcherera.
310S: Kutentha kwambiri (mpaka 1100°C), koyenera kugwiritsidwa ntchito pazigawo za uvuni.
Chitsulo Chosapanga Dzimbiri cha Ferritic (400 series, mwachitsanzo, 430, 409, 439) Mapepala achitsulo chosapanga dzimbiri cha Ferritic ali ndi 10.5%–27% chromium, mpweya wochepa kwambiri (<0.1%), ndipo ndi nickel yochepa kwambiri kapena yopanda. Ndi maginito ndipo amalimbana bwino ndi kusweka kwa dzimbiri, koma mawonekedwe awo ndi kulimba kwawo ndizochepa poyerekeza ndi chitsulo chosapanga dzimbiri cha austenitic. Sangalimbikitsidwe ndi kutentha. Ntchito zodziwika bwino: makina otulutsa utsi wamagalimoto, mapanelo omangira nyumba, ndi zida zamagetsi zamkati. M'malo ofatsa, giredi 430 ndi njira yotsika mtengo yodziwika bwino m'malo mwa giredi 304.
Chitsulo Chosapanga Dzimbiri Cha Duplex (monga, 2205, 2507) Chitsulo chosapanga dzimbiri cha Duplex chili ndi kapangidwe kakang'ono kopangidwa ndi zinthu za austenitic ndi ferritic (pafupifupi 50/50). Chifukwa cha kuchuluka kwa chromium (21-26%), kuchuluka kwa nickel (4-7%), ndi kuchuluka kwa molybdenum (0-4%), chitsulo chosapanga dzimbiri cha 2205 chili ndi mphamvu yochulukitsa pafupifupi kawiri kuposa chitsulo chosapanga dzimbiri cha austenitic, pomwe chimakhalabe ndi mphamvu yolimbana ndi chloride stress corrosion cracking. Chitsulo chosapanga dzimbiri cha 2205 chimagwiritsidwa ntchito kwambiri m'ma tanker a mankhwala, desalination ya madzi a m'nyanja, ndi pulp digesters. Mphamvu yake yayikulu imalola kugwiritsa ntchito mapepala opyapyala, motero kuchepetsa kulemera ndi mtengo.
Chitsulo chosapanga dzimbiri cha Martensitic (monga, 410, 420) chili ndi 11-17% ya chromium ndi carbon yambiri (0.1-1.2%), zomwe zimapangitsa kuti zikhale zolimba chifukwa cha kutentha. Ndi zamaginito, zolimba, komanso zosatha, koma kukana kwawo dzimbiri n'kochepa kuposa kwa zitsulo zosapanga dzimbiri za austenitic kapena duplex.
Kusiyana kwakukulu pakati pa mbale zachitsulo zosapanga dzimbiri 304 ndi 316: chitsulo chosapanga dzimbiri 304, chomwe timakumana nacho tsiku ndi tsiku, ndi muyezo wa chitsulo chosapanga dzimbiri chomwe chimadyedwa bwino komanso mfumu ya kugwiritsa ntchito bwino ndalama m'nyumba. Chili ndi mphamvu yolimbana ndi dzimbiri, kupewa dzimbiri, komanso kukana kutentha kwambiri. Pa makapu otetezedwa, ziwiya za patebulo, masinki akukhitchini, zida zopangira chakudya, ndi zida za m'bafa, 304 ndiye chisankho chabwino kwambiri. Ndi yotetezeka, yopanda poizoni, komanso yolimba dzimbiri kuti igwiritsidwe ntchito tsiku ndi tsiku, yoyenera zinthu zambiri zapakhomo, ndipo imapereka kulimba kwapadera.
Koma chitsulo chosapanga dzimbiri cha 316 ndi chinthu chapamwamba kwambiri chomwe chimagwiritsidwa ntchito m'mafakitale. Chimawonjezera molybdenum ku 304, zomwe zimapangitsa kuti chisagwere bwino, chisagwere asidi ndi alkali, komanso chimathandiza kuti chisagwere kutentha kwambiri komanso dzimbiri m'madzi a m'nyanja. Chimagwiritsidwa ntchito kwambiri m'ziwiya zapamwamba zakukhitchini, zida zamankhwala, mapaipi a mankhwala, komanso m'malo opezeka pagombe. Ngakhale kuti sichofunikira pa ntchito zapakhomo za tsiku ndi tsiku, 316 ndiye yankho labwino kwambiri pakugwiritsa ntchito komwe kumafuna kugonjetsedwa kwambiri ndi dzimbiri.
Kusiyana kwina kwakukulu kuli pamtengo wake; chifukwa cha kuchuluka kwa nickel ndi molybdenum, chitsulo chosapanga dzimbiri cha 316 nthawi zambiri chimakhala chokwera mtengo kuposa chitsulo chosapanga dzimbiri cha 304. Chifukwa chake, kusankha pakati pa zitsulo ziwirizi nthawi zambiri kumadalira zofunikira zinazake zogwiritsidwa ntchito, kuphatikizapo zoletsa bajeti ndi zinthu zachilengedwe.
Chitsulo chosapanga dzimbiri ndi chinthu chogwiritsidwa ntchito kwambiri paukadaulo, makamaka magiredi 304 ndi 316, omwe amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe awo apadera komanso ntchito zawo. Kaya ndi mafakitale opangira chakudya, zomangamanga, magalimoto, zamankhwala, mankhwala, kapena mphamvu, mapepala achitsulo chosapanga dzimbiri akhala chisankho chodalirika kwa mainjiniya ndi opanga. Pamene mafakitale akupitilizabe kusintha ndipo kufunikira kwa zipangizo zolimba komanso zosagwira dzimbiri kukupitirira kukula, kufunika kwa mapepala achitsulo chosapanga dzimbiri kudzangowonjezeka.
Ngati mukufuna kugula zinthu zopangidwa ndi chitsulo chosapanga dzimbiri, chonde dinani kuti tilumikizane nafe kuti tikupatseni upangiri. Jindalai Steel Group Co., Ltd. ikupatsani mayankho aukadaulo kwambiri.
