Austenitic Stainless Steel Grades, Makhalidwe ndi Ubwino

M'nthawi ino yofunafuna zatsopano komanso zida zogwira ntchito kwambiri, chitsulo chosapanga dzimbiri cha austenitic wakhala nyenyezi yowoneka bwino m'makampani amakono chifukwa cha mawonekedwe ake apadera, machitidwe osiyanasiyana, komanso maubwino osayerekezeka. M'nkhaniyi, tiyeni tiwulule chinsinsi cha austenitic zitsulo zosapanga dzimbiri ndikufufuza austenitic zosapanga dzimbiri magiredi, makhalidwe, ndi ubwino.

Kodi Austenitic Stainless Steel ndi chiyani?

Chitsulo chosapanga dzimbiri cha Austenitic ndi aloyi wachitsulo wokhala ndi chromium ndi faifi tambala monga zinthu zake zazikulu zopangira alloying, ndipo kapangidwe kake kamakhala kokwanira. Mapangidwe ake oyambira ndi Cr18Ni8 (18-8), omwe amatha kusinthidwa kukhala magiredi osiyanasiyana. Zomwe zili pamwamba pa chromium zimathandizira kwambiri kukana kwa dzimbiri kwa chitsulo, monga wandiweyani kwambiri komanso wolimba kwambiri wa chromium oxide woteteza wosanjikiza umapangidwira pamwamba.

Kuti muchepetse kuuma kwa chitsulo cha chromium, ndikuwongolera kulimba kwake komanso kulimba kwake, nickel osachepera 8% ayenera kuwonjezeredwa kuti apange chitsulo chokwanira cha austenitic chokhala ndi mawonekedwe apakati, omwe amatha kugwira ntchito mozizira, kuwotcherera mosavuta, ndipo amakhala ndi zabwino kwambiri. kutentha kwambiri komanso kutentha kwapansi, motero kukhala ndi ntchito zambiri.

Kodi Austenitic Stainless Steel ndi Zotani?

Chitsulo chosapanga dzimbiri cha Austenitic chimadziwika ndi kuchuluka kwa chromium ndi nickel. Zomwe zimapangidwa ndi chitsulo chosapanga dzimbiri cha austenitic ndi 18% chromium ndi 8% nickel. Kapangidwe kameneka kamapangitsa chitsulo kukhala ndi austenitic microstructure, chomwe chimapangitsa kuti chisawonongeke kwambiri poyerekeza ndi zitsulo zosapanga dzimbiri za ferritic ndi martensitic. Kuchuluka kwa chromium kumaperekanso chitsulo chosapanga dzimbiri cha austenitic kukana kutentha kwambiri. kumasulira ku Chingerezi.

Maphunziro a Austenitic Stainless Steel:

Chitsulo chosapanga dzimbiri cha Austenitic chimagawidwa m'magulu 200 ndi 300, okhala ndi 16% mpaka 30% chromium ndi 2% mpaka 20% nickel kuti apititse patsogolo mawonekedwe apamwamba, mawonekedwe, kukana dzimbiri, komanso kukana kuvala. Mitundu yodziwika bwino ya austenitic alloys ndi giredi 304 ndi 316.

Ena otchuka austenitic zitsulo zosapanga dzimbiri onjezerani 304L, 316L, 309S, 310S, 317L, 321, 347H, etc. Dual-gawo zosapanga dzimbiri magiredi, monga 2205 (22% chromium, 5% faifi tambala), amakhalanso m'gulu austenitic.

Magiredi a Austenitic Stainless Steel Opezeka: 301, 304, 304L, 304LN, 321, 347, S30430, 316, 316L, 316LN, S31653, Zamgululi, 317l.

Kodi Ubwino wa Austenitic Stainless Steel Ndi Chiyani?

Chitsulo chosapanga dzimbiri cha Austenitic ndi chitsulo chosapanga dzimbiri chokhala ndi austenite. Austenite ndi mtundu wachitsulo womwe umakhala wokhazikika pa kutentha kwambiri. Izi zimapangitsa chitsulo chosapanga dzimbiri cha austenitic kukhala choyenera kwa ntchito zomwe kutentha kwambiri kumakhala kofala, monga malo ogulitsa mafakitale.

Chitsulo chosapanga dzimbiri cha Austenitic chimakhalanso ndi kukana kwa dzimbiri. Izi zimapangitsa kuti zikhale zabwino kwa mapulogalamu omwe akhudzidwa ndi dzimbiri, monga kukonza chakudya kapena zida zamankhwala. Chitsulo chosapanga dzimbiri cha Austenitic ndichopanda maginito. Izi zimapangitsa kuti zikhale zabwino kwa mapulogalamu omwe safuna zipangizo zamagetsi, monga zida zamagetsi.

Zambiri za Austenitic Stainless Steel

Chitsulo chosapanga dzimbiri cha Austenitic chimakonda kuwonongeka kwa intergranular. Kugwiritsa ntchito zida za carbon ultra-low, kuwonjezera zinthu zomwe zimapanga carbides mosavuta (titaniyamu), komanso kugwiritsa ntchito mankhwala olimba ndi njira zothandizira kupewa dzimbiri la intergranular.

Chloride ions ndi owopsa kwambiri ku chitsulo chosapanga dzimbiri cha austenitic ndipo amayambitsa kupsinjika kwa dzimbiri. Chifukwa chake, zigawo zomwe zimakhala ndi kupsinjika kwamphamvu ndikukhudzana ndi ayoni a chloride (monga zotengera zokakamiza) ziyenera kuchepetsa kwambiri ma ayoni a chloride pakati, kapena kugwiritsa ntchito njira yolumikizira kuti athetse kupsinjika kotsalira.
