Grade 3CR12 Stainless steel igiredhi yakaderera yechromium ine simbi isina tsvina yakagadzirwa nekugadzirisa zvinhu zvegiredhi 409 simbi.Inopikisa kunyorova uye kunyorova kupfeka.Yakatangwa neColumbus Stainless Company pasi pechiratidzo chakanyoreswa "3CR12"Mamwe mazita egiredhi iri anosanganisira UNS03/S4104/S4107/S4107/S4107/41907 S41907/41907.
Mamwe mazita akaenzana ne3CR12 mamakisi anosanganisira ASME SA240 mamakisi, ASTM A240/A240M mamakisi, uye EN 10088.2.Zvisinei, EN 10028.7 inovharawo kirasi 1.4003, iyo inoumba simbi isina tsvina yezvinangwa zvekumanikidza.
Zvikamu zvinotevera zvinopa zvivakwa zvakakosha zvegiredhi 3CR12 simbi isina simbi coil, shiti uye ndiro mukuteerana neEuronorm S41003, S40977, ASTM A240/A240M uye EN 10088.2 1.4003.
Izvo zviri pamusoro zvinongori kuenzanisa.Tafura iyi inotarisirwa kupa kuenzanisa kwezvinhu zvinoshanda zvakafanana, uye zvinyorwa hazvisi pamutemo.Mashoko ekutanga anogona kuongororwa kana kuenzana chaiko kuchidikanwa.
Giredhi 3CR12 simbi isina tsvina inogona kushandiswa mumashandisirwo apo aluminium, galvanized kana carbon steel inopa migumisiro yakaipa nekuda kwekudzivisa kwayo kune yakasimba acids uye mabhesi, pamwe nekutsemuka kunokonzerwa nekloride stress corrosion.Zvisinei, kusiyana neGiredhi 304, Giredhi 3CR12 ine kushorwa kwakaderera kune crevice uye gomba corrosion muhupo hwe chlorides.
Mumamiriro ezvinhu akadzikama, giredhi re3CR12 rakavandudza kushivirira kumvura nemakloridi, sezvo kusvibiswa kwekloride yemukati kunoderedzwa ne nitrate uye sulfate ions. Chimwe chezvakashata zvikuru zvegiredhi 3CR12 ndechokuti pamusoro pezvinhu zvakasvibiswa zvishoma kana zvichiratidzwa kune chero rudzi rwekushongedza kunogumira kune chero rudzi rwekushongedza.
3CR12 giredhi Stainless simbi inoratidzira kukanganisa kupikisa pakati pe600 ne750 ° C muhupo hwemhepo uye pakati pe450 ne600 ° C munzvimbo yakamanikidzwa. Nyaya yacho inova brittle nekuratidzwa kwenguva refu kune tembiricha pakati pe450 ne550 ° C.Zvisinei, iyo nyaya hairasikirwe.
Giredhi 3CR12 simbi isina tsvina yakanyungudutswa pa700 kusvika 750 ° C, yakakamurwa kuita zvikamu zve 25mm, chikamu chimwe nechimwe chakanyoroveswa kwemaawa 1.5. Zvadaro rega zvinhu zvitonhore.Kuchengetedza kunofanira kutorwa kudzivirira kuoma panguva yekupisa kupisa.Iyo mechanical properties uye kusagadzikana kwegorosi kwegiredhi iyi kunokonzerwa nekudzima kurapwa.
Nzira dzekugadzira dzinoshandiswa kune austenitic stainless steels dzinogona kushandiswa kugiredhi 3CR12 simbi isina tsvina.Fungisisa hutekinoroji hwekupisa hushoma hwakadai seGMAW (MIG) uye GTAW (TIG) .In welding, giredhi 309 filler wire pre-certified to AS 1554.6 inosarudzwa.Zvisinei, 30L wire 308L 308L grade 308L uye 308L wire 308L. anoshandiswawo muzviitiko zvakawanda.Chero ruvara rwechigadzirwa chakatengeswa chinogona kubviswa uchishandisa gasi rekutsigira kana maitiro akadai sekuchenesa uye pickling.
Iyo machinability ye3CR12 giredhi Stainless simbi inenge 60% yeiyo yesimbi yakapfava.Kushanda kwavo kuomarara mwero yakaderera pane yeaustenitic steels, saka hapana yakakosha machining nzira dzinodiwa.
Giredhi 3CR12 mashizha esimbi asina tsvina anowanikwa muhutano hweHot Rolled Annealed uye Pickled (HRAP) kupera, uye mapeji anowanikwa mu 2B kana 2D kupera.Kupera kwakasviba kunogonawo kugadzirwa kubva kune inopisa yakaputirwa zvinhu, zvichisiya nzvimbo yakasviba oxidized pamusoro pesimbi.3CR12 grade black finish ine yakanaka corrosion kupfeka kusagadzikana uye kushandiswa kwakaderera kwakakodzera kune friction.
