304 / 304L Machubu Opanda Zitsulo Opanda Msokonezo
Chiyambi cha Zamalonda
Aloyi 304 (S30400) ndi 304L (S30403) zitsulo zosapanga dzimbiri ndizosiyana za 18 peresenti ya chromium - 8 peresenti ya nickel austenitic alloy, alloy omwe amadziwika kwambiri komanso omwe amagwiritsidwa ntchito mobwerezabwereza m'banja lazitsulo zosapanga dzimbiri. 304/L chitsulo chosapanga dzimbiri chili ndi zida zabwino kwambiri zopangira. Kusasunthika kwake kumapangitsa kuti ipangidwe mosavuta kuti ipse, kupindika ndi kupindika. Kugwiritsa ntchito bwino komanso kutsika kwa sulfure kumathandizira kutenthetsa kwabwino pamapulogalamu omwe amafunikira.
Mphamvu zazikulu, kukana kwa dzimbiri komanso kuchepetsedwa kwa kaboni kumapangitsa Alloy 304 ndi 304L Stainless Steels kukhala yothandiza pakugwiritsa ntchito komwe kuwotcherera kumafunika. Zogwiritsidwa ntchito zimaphatikizapo zomangira zomanga ndi zochepetsera, zida zowotcherera zama mankhwala, nsalu, mapepala, zida zopangira mankhwala ndi mafakitale.
Ubwino wina ndi kukana kwake kwa okosijeni, mawonekedwe abwino kwambiri, kuphweka kwa kupanga ndi kuyeretsa, mphamvu yabwino kwambiri ya kulemera kwa chiŵerengero ndi kulimba kwabwino pa kutentha kwa cryogenic Kwa malo owononga kwambiri, zomwe zili m'munsi mwa Type 304L zimakondedwa chifukwa cha chitetezo chake chachikulu cha intergranular corrosion.
Type 304L chitsulo chosapanga dzimbiri ndi mtundu wowonjezera wa kaboni wa 304 zitsuloaloyi. Kutsika kwa kaboni mu 304L kumachepetsa mpweya woyipa kapena wowopsa wa carbide chifukwa cha kuwotcherera. 304L imatha kugwiritsidwa ntchito "monga wowotcherera" m'malo ochita dzimbiri, ndipo imathetsa kufunikira kwa annealing.
Gululi lili ndi makina otsika pang'ono kuposa kalasi ya 304, koma amagwiritsidwabe ntchito kwambiri chifukwa cha kusinthasintha kwake. Monga chitsulo chosapanga dzimbiri cha Type 304, chimagwiritsidwa ntchito kwambiri popanga moŵa ndi kupanga vinyo, komanso pazifukwa zoposa zamakampani azakudya monga zotengera mankhwala, migodi, ndi zomangamanga. Ndibwino kuti mugwiritse ntchito m'zigawo zachitsulo monga mtedza ndi ma bolts omwe amakumana ndi madzi amchere.
