Kukana kutentha kwa 309S 310S ndi 253MA kusiyana kwa chitsulo chosapanga dzimbiri.

Wamba kutentha zosagwira zosapanga zitsulo zambiri ogaŵikana mitundu itatu, 309S, 310S ndi 253MA, kutentha zosagwira zitsulo zambiri ntchito popanga boilers, turbines nthunzi, ng'anjo mafakitale ndi ndege, petrochemical ndi zigawo zina mafakitale mu mkulu kutentha ntchito. magawo.

1.309s: (OCr23Ni13) mbale yachitsulo chosapanga dzimbiri

Makhalidwe: Imatha kupirira kutentha mobwerezabwereza pansi pa 980 ℃, ndi mphamvu ya kutentha kwambiri, kukana kwa okosijeni ndi kukana kwa carburizing.

Kugwiritsa ntchito: zida za ng'anjo, zitha kugwiritsidwa ntchito popanga zitsulo zotentha, chromium yake yayikulu ndi nickel imatsimikizira kukana kwa dzimbiri komanso kukana kwa okosijeni.

Poyerekeza ndi aloyi ya austenitic 304, imakhala yamphamvu pang'ono kutentha.M'moyo weniweni, ukhoza kutenthedwa mobwerezabwereza pa 980 ° C kuti ukhalebe ndi ntchito yabwino.310s: (0Cr25Ni20) mbale yachitsulo chosapanga dzimbiri.

2.310s: (OCr25Ni20) mbale yachitsulo chosapanga dzimbiri

Makhalidwe: Chitsulo chosapanga dzimbiri cha chromium-nickel austenitic chokhala ndi makina abwino otenthetsera komanso kukana kwa dzimbiri muzofalitsa zotulutsa ma oxidizing.Oyenera kupanga zigawo zosiyanasiyana ng'anjo, kutentha kwambiri 1200 ℃, mosalekeza ntchito kutentha 1150 ℃.

Kugwiritsa ntchito: zida za ng'anjo, zida zoyeretsera magalimoto.

Chitsulo chosapanga dzimbiri cha 310S ndi chitsulo chosapanga dzimbiri cha austenitic chosapanga dzimbiri chomwe chimagwiritsidwa ntchito m'malo osiyanasiyana otentha komanso owononga.Ndi chisankho chabwino kwambiri pamafakitale a petrochemical, mankhwala, ndi kutentha, komanso zida za ng'anjo ndi ntchito zina zotentha kwambiri.Chovala chachitsulo chosapanga dzimbiri cha 310S ndi pepala lathyathyathya, lopyapyala lopangidwa kuchokera ku aloyiyi.

3.253MA (S30815) mbale yachitsulo chosapanga dzimbiri

Makhalidwe: 253MA ndi chitsulo chosapanga dzimbiri cha Austenitic chosagwira kutentha chomwe chimapangidwira ntchito zomwe zimafuna mphamvu zambiri zokwawa komanso kukana kwa dzimbiri.ntchito yake kutentha osiyanasiyana 850-1100 ℃.

253MA ndi mtundu wapadera wazitsulo zosapanga dzimbiri zomwe zimapangidwira ntchito zotentha kwambiri.Amapereka kukana kwambiri kwa okosijeni, sulfidation, ndi carburization pa kutentha kokwera.Izi zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza omwe amakhudza kutentha ndi dzimbiri, monga gawo la petrochemical, magetsi opangira magetsi, ndi ng'anjo zamafakitale.Mapepala a 253MA ndi zidutswa zopyapyala zopangidwa ndi aloyi iyi.Amagwiritsidwa ntchito pazinthu zosiyanasiyana zomwe kuphatikiza kukana kutentha kwambiri komanso kukana kwa dzimbiri ndikofunikira.Mapepalawa amatha kudulidwa ndikupangidwa m'mawonekedwe osiyanasiyana kuti akwaniritse zofunikira za polojekiti.

Mapepala a 253MA, Mapepala Opangidwa ndi Mankhwala

253MA Plate Mechanical katundu

253MA Plate Corrosion resistance ndi malo ogwiritsira ntchito kwambiri:

1.Kukaniza kwa Corrosion: 253MA ili ndi kukana kwa okosijeni kwabwino kwambiri, kukana kwa dzimbiri, komanso mphamvu zamakina zamphamvu kwambiri.Ndiwothandiza makamaka mkati mwa kutentha kwa 850 mpaka 1100 ° C.

2.Kutentha Kwambiri: Kuti mugwiritse ntchito bwino, 253MA ndi yoyenera kugwiritsidwa ntchito mkati mwa kutentha kwa 850 mpaka 1100 ° C.Pa kutentha pakati pa 600 ndi 850 ° C, kusintha kwapangidwe kumachitika, zomwe zimapangitsa kuti pakhale kuchepa kwa mphamvu pa kutentha.

3.Mechanical Strength: Aloyiyi imaposa zitsulo zosapanga dzimbiri wamba, monga 304 ndi 310S, potengera mphamvu yanthawi yayitali pa kutentha kosiyanasiyana ndi 20%.

4.Chemical Composition: 253MA imakhala ndi mankhwala oyenerera omwe amachititsa kuti azigwira ntchito mwapadera pa kutentha kwa 850-1100 ° C.Imawonetsa kukana kwambiri kwa okosijeni, kupirira kutentha mpaka 1150 ° C.Imaperekanso kukana kwamphamvu kwambiri komanso kulimba kwa fractures.

5.Kukaniza kwa Corrosion: Kuphatikiza pa mphamvu zake zotentha kwambiri, 253MA imawonetsa kukana kwambiri kutentha kwapamwamba komanso kuwononga burashi m'madera ambiri a mpweya.

6.Strength: Imakhala ndi mphamvu zokolola zambiri komanso mphamvu zolimba pa kutentha kwakukulu.

7.Formability ndi Weldability: 253MA imadziwika ndi mawonekedwe ake abwino, weldability, ndi machinability.
