Gulu la 3CR12 zitsulo zosapanga dzimbiri ndi mtengo wotsika wa chromium wokhala ndi chitsulo chosapanga dzimbiri chopangidwa ndi kusintha zinthu zazitsulo za grade 409. Imakana kuwononga pang'ono ndi kuvala konyowa.Inapangidwa poyamba ndi Columbus Stainless Company pansi pa chizindikiro cholembedwa "3CR12".
Maudindo ena ofanana ndi masukulu a 3CR12 akuphatikizapo masukulu a ASME SA240, ASTM A240/A240M giredi, ndi EN 10088.2.Komabe, EN 10028.7 imaphatikizanso kalasi ya 1.4003, yomwe imapanga zitsulo zosapanga dzimbiri pazokakamiza.
Magawo otsatirawa adzapereka zinthu zofunika za kalasi ya 3CR12 koyilo yachitsulo chosapanga dzimbiri, pepala ndi mbale potsatira Euronorm S41003, S40977, ASTM A240/A240M ndi EN 10088.2 1.4003.
Zomwe zili pamwambazi ndizofanizira movutikira.Gome ili likufuna kupereka kufananitsa kwa zida zogwirira ntchito, ndipo zofotokozera sizili zalamulo.Zolemba zoyambirira zitha kutsimikiziridwa ngati zofunikira zenizeni zikufunika.
Kalasi 3CR12 zitsulo zosapanga dzimbiri angagwiritsidwe ntchito ntchito pamene aluminiyamu, kanasonkhezereka kapena mpweya zitsulo amapereka zotsatira zoipa chifukwa cha kukana zidulo amphamvu ndi zapansi, komanso akulimbana chifukwa chloride nkhawa corrosion.
Pansi ozungulira mikhalidwe, ndi kalasi 3CR12 bwino kulolerana kwa madzi ndi mankhwala enaake, monga corrosiveness wa zinthu za kolorayidi ndi mitigated ndi nitrate ndi sulphate ayoni. Mmodzi wa kuipa waukulu kalasi 3CR12 ndi kuti pamwamba pa zinthu zina dzimbiri pang'ono dzimbiri pamene anaonekera kwa zinthu zokongoletsa ndi malire kwa chilengedwe.
Chitsulo chosapanga dzimbiri cha 3CR12 chikuwonetsa kukana koyipa pakati pa 600 ndi 750 ° C pamaso pa mpweya komanso pakati pa 450 ndi 600 ° C m'malo oponderezedwa. Zinthuzo zimakhala zopanda mphamvu ndi kukhudzana ndi kutentha kwa nthawi yayitali pakati pa 450 ndi 550 ° C.
Gulu la 3CR12 zitsulo zosapanga dzimbiri zimayikidwa pa 700 mpaka 750 ° C, zimagawidwa m'magawo a 25mm, chigawo chilichonse chimanyowa kwa maola 1.5. Kenaka mulole zinthuzo zizizizira.Kusamala kumayenera kutengedwa kuti zisawonongeke panthawi ya kutentha.
Njira zowotcherera zomwe zimagwiritsidwa ntchito pazitsulo zosapanga dzimbiri za austenitic zingagwiritsidwe ntchito pazitsulo zosapanga dzimbiri 3CR12. Ganizirani njira zamakono zopangira kutentha monga GMAW (MIG) ndi GTAW (TIG) .Mu kuwotcherera, waya wa grade 309 filler pre-certified to AS 1554.6 ndi okondedwa. amagwiritsidwanso ntchito nthawi zambiri.Kusintha kulikonse muzinthu zogulitsidwa kumatha kuchotsedwa pogwiritsa ntchito mpweya wothandizira kapena njira monga kuyeretsa ndi pickling.
The machinability 3CR12 kalasi zitsulo zosapanga dzimbiri ndi pafupifupi 60% ya zitsulo wofatsa.Ntchito yawo kuumitsa mlingo ndi otsika kuposa zitsulo austenitic, kotero palibe makina makina apadera chofunika.
Mapepala a zitsulo zosapanga dzimbiri 3CR12 akupezeka mumtundu wa Hot Rolled Annealed and Pickled (HRAP), ndipo ma coil amapezeka mu 2B kapena 2D finish.
