SUS304 (SUS amatanthauza chitsulo chosapanga dzimbiri chachitsulo) chitsulo chosapanga dzimbiri cha austenite chimatchedwa SS304 kapena AISI 304 m'Chijapani.Kusiyana kwakukulu pakati pa zida ziwirizi sizinthu zakuthupi kapena mawonekedwe, koma momwe zimatchulidwira ku United States ndi Japan.
Komabe, pali kusiyana kwamakina pakati pazitsulo ziwirizi.Mu chitsanzo chimodzi, zitsanzo za SS304 zopezedwa kuchokera ku US ndi zitsanzo za SUS304 zotengedwa kuchokera ku Japan zidatumizidwa ku labotale kuti akayesedwe.
SUS304 ( JIS muyezo) ndi imodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri pazitsulo zosapanga dzimbiri.Amapangidwa ndi 18% Cr (chromium) ndi 8% Ni (nickel).Ikhoza kukhalabe ndi mphamvu ndi kukana kutentha pa kutentha kwakukulu ndi kochepa.Komanso ali weldability wabwino, katundu makina, ozizira workability ndi kukana dzimbiri pa firiji. SS304 (ANSI 304) ndi chitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito kwambiri popanga zida zina zosapanga dzimbiri, ndipo nthawi zambiri amagulidwa pansi paziziziritsa kapena kuzizira.Mofanana ndi SUS304, SS304 ilinso ndi 18% Cr ndi 8% Ni, choncho imatchedwa 18/8. SS304 ali weldability wabwino, kukana kutentha, kukana dzimbiri, otsika kutentha mphamvu, workability, makina katundu, kutentha mankhwala si owumitsidwa, kupinda, kupondaponda isothermal workability ndi zabwino.SS304 imagwiritsidwa ntchito kwambiri m'mafakitale ambiri, kuphatikiza chakudya, ntchito zamankhwala ndi zokongoletsa. Kuphatikizika kwa Chemical kwa SUS304 ndi SS 304

Kukana kwa dzimbiri kwa 304 chitsulo chosapanga dzimbiri Monga tonse tikudziwa, 304 zitsulo zosapanga dzimbiri zimagwira ntchito bwino m'malo osiyanasiyana am'mlengalenga komanso media zowononga.Komabe, m'malo otentha a chloride, kutentha kumapitilira 60 ° C, kumakhala kosavuta kuyika dzimbiri, kuphulika kwa mng'alu ndi kupsinjika kwamphamvu.Pakutentha kozungulira, imawonedwanso kuti imatha kupirira madzi akumwa omwe amakhala pafupifupi 200 mg/l chloride.Makhalidwe athupi a SUS304 ndi SS304
Zida ziwirizi zili pafupi kwambiri ndi thupi ndi mankhwala, choncho n'zosavuta kunena kuti ndizofanana.Momwemonso, kusiyana kwakukulu pakati pa mayiko awiriwa ndikuyimira pakati pa United States ndi Japan.Izi zikutanthauza kuti pokhapokha ngati malamulo enieni kapena zofunikira zikufotokozedwa ndi dziko kapena kasitomala, chinthu chilichonse chingagwiritsidwe ntchito mosiyana.
