1. Zinthu zakuthupi
The thupi katundu 202 ndi lolingana 300 mndandanda zitsulo mu boma chithandizo mankhwala, katundu thupi la 200 mndandanda ndi 300 mndandanda pafupifupi ofanana. Komabe, kusintha kwa permeability pambuyo ntchito ozizira ndi osiyana. Chifukwa cha kusiyana kosiyana kwa mutagenic martensite panthawi yozizira, kuwonjezeka kwa permeability kumakhala kochepa kusiyana ndi mndandanda wa 200 ndi mndandanda wa 300.
2. Makhalidwe amakina
201 ndi 202 ndizosiyana ndi zida zina 200. Monga 301 ndi 302, onse ndi zitsulo zosapanga dzimbiri zosapanga dzimbiri za austenitic zokhala ndi katundu wowumitsa ntchito. Zitsulo izi zimakhala ndi zokhotakhota zolimba. 201 ndi 301 ndi 202 ndi 302 ali ndi mawonekedwe owumitsa ofanana. 201,301 Kuvuta kwa ntchito ndikokulirapo. Kuchuluka kwa martensite opangidwa kumasiyana pa giredi iliyonse. 202,304 martensite imapanga zochepa kwambiri, ndipo kugwira ntchito molimbika makamaka kumadalira kupunduka. Kwazitsulo pansi pa 204 ndi 204L, pafupifupi kuuma kwa ntchito kumadalira kusokoneza. The makina katundu ndi permeability wa CrMnN mndandanda zipangizo zikuwonetsedwa mu Table 5. Kuuma kwa zitsulo izi mu njira yothetsera boma ndi za HV250, ndipo mphamvu pambuyo ozizira anagubuduza kuumitsa ndi apamwamba, ndipo Hv akhoza kufika 500, koma permeability. akadali otsika kuposa 1.005 mdziko muno.

Kugwiritsa ntchito:

Chitoliro cha 202 chosapanga dzimbiri ndi cha mndandanda wa 200. Chitukuko choyambirira chinalowa m'malo mwa chitsulo chosapanga dzimbiri cha 18-8 chromium-nickel austenitic ndi manganese ndi nayitrogeni m'malo mwa faifi tambala. 18-8 mtundu wa Cr-Ni zitsulo zosapanga dzimbiri 301, 302, 304 (kuphatikizapo 321) zimapanga zoposa 50% za chiwerengero cha zitsulo zosapanga dzimbiri. Magulu azitsulowa ali ndi zinthu zabwino kwambiri monga kukana dzimbiri, makina amakina, kutentha kwambiri komanso kutsika kwa kutentha, kapangidwe kazinthu, ndi zokongoletsera. Amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana kuchokera kuzinthu zankhondo mpaka zankhondo komanso zomangamanga. Zida zapakhomo, zida zakukhitchini ndi ziwiya, zoyendera, chitetezo cha chilengedwe, zomangamanga zamatauni; ndege zankhondo, zakuthambo, mafakitale anyukiliya, zombo; minda ya mafakitale a mankhwala, feteleza, mafuta, nsalu, kusindikiza, mapepala, mphamvu. Table 1 imatchula mndandanda wa AISI200 wazitsulo zosapanga dzimbiri za manganese zomwe zili ndi austenitic. Choncho maphunziro oyambirira a 201, 202, 204, 205, 206 akugwirizana ndi Cr-Ni mndandanda 301, 302, 304, 305, 316. Kenaka, 211 inapangidwa kuti igwiritse ntchito magiredi achitsulo a carbon nitrogen, Mn, ndi Cu-added zitsulo. kwa ntchito yozizira. 201L, 201LN, etc. ndi kusintha kwa 201 kuthetsa vuto la intergranular stress corrosion.
High-nitrogen CrMnN austenitic zitsulo zosapanga dzimbiri zimakhala ndi mphamvu zambiri, zolimba, kukana kuvala kwambiri, zopanda maginito, kukana kwa dzimbiri ndi makhalidwe ena, ndipo zimakhala ndi zosowa zosiyanasiyana pamakampani. M'tsogolomu, padzakhala chitukuko chachikulu m'madera otsatirawa:
1. Chitsulo chapamwamba cha nayitrogeni CrMnNiN chokhala ndi mphamvu zambiri, kukana kwa dzimbiri komanso kulimba kwa kutentha kochepa kungagwiritsidwe ntchito pa ndege, zamlengalenga ndi zombo zokhala ndi ndodo zabwino kwambiri zogwirira ntchito, mawaya, forgings, mbale zapakati, ndi mbale zopyapyala kupanga zotengera, mapaipi, mavavu, Zingwe, etc.
2. Chitsulo chosavala chosavala, chopanda dzimbiri, cholimba kwambiri komanso chapamwamba cha nitrogen CrMnN austenitic chosapanga dzimbiri chingapereke zida zamakina zosagwira, zosavala komanso zopangira zida zamigodi zamakampani amigodi.
3. Non-magnetic, high-power, corrosion-resistant, high-nitrogen CrMnMoN austenitic zitsulo zosapanga dzimbiri, zomwe zingapereke makola obowola opanda maginito a minda ya mafuta, ndi mphete zopanda maginito zotetezera magetsi opanga magetsi. 4. High pitting resistance, crevice corrosion resistance and high nitrogen CrNiMnMoN Austenitic stainless steel ingathe kupereka zipangizo zopangira kutentha kwa madzi a m'nyanja, zipangizo zochotsera madzi a m'nyanja, ndi zipangizo zopangira gasi desulfurization m'mafakitale a m'mphepete mwa nyanja.
