Kodi pepala la 304 zitsulo zosapanga dzimbiri limapangidwa bwanji?

304 zitsulo zosapanga dzimbiri ndi mtundu wa chitsulo chosapanga dzimbiri cha austenitic chomwe chimagwiritsidwa ntchito kwambiri pamafakitale osiyanasiyana chifukwa cha kukana kwake kwa dzimbiri, mphamvu, komanso ductility. Zimapangidwa ndi zinthu zapadera zomwe zimapatsa mawonekedwe ake apadera komanso mawonekedwe ake.

 

Chigawo chachikulu

Zigawo zazikulu za pepala 304 zosapanga dzimbiri ndi chitsulo, kaboni, chromium, ndi faifi tambala. Chitsulo ndicho maziko, kupereka chitsulo ndi mphamvu zake ndi ductility. Mpweya umawonjezedwa kuti chitsulocho chikhale cholimba komanso kuti chikhale cholimba, koma chiyenera kukhala chochepa kwambiri kuti chisachepetse kukana kwa dzimbiri.

 

Chromium element

Chromium ndiye chinthu chofunikira kwambiri mu 304 chitsulo chosapanga dzimbiri, chifukwa ndi chomwe chimapangitsa kuti chisawonongeke. Chromium imapanga zosanjikiza zoteteza za oxide pamwamba pa chitsulo zikakumana ndi okosijeni, kuteteza dzimbiri ndi dzimbiri. Muzitsulo zosapanga dzimbiri 304, zomwe zili mu chromium zimakhala pafupifupi 18-20% polemera.

 

Nickel element

Nickel ndi gawo lina lofunika la 304 zitsulo zosapanga dzimbiri, zomwe zimapezeka mumagulu a 8-10% ndi kulemera kwake. Nickel imapangitsa kuti chitsulocho chikhale cholimba komanso cholimba, chomwe chimachititsa kuti chisaphwanyeke komanso kusweka. Imawonjezeranso kukana kwa dzimbiri, makamaka m'malo okhala ndi chloride.

 

Zinthu zina zochepa

Kuphatikiza pa zinthu zazikuluzikuluzi, zitsulo zosapanga dzimbiri 304 zimathanso kukhala ndi zinthu zina zazing'ono monga manganese, silicon, sulfure, phosphorous, ndi nayitrogeni. Zinthuzi zimawonjezedwa kuti zisinthe zitsulo zachitsulo ndikuwongolera magwiridwe antchito ake.

 

Mwachidule, mapangidwe a 304 zitsulo zosapanga dzimbiri amachokera ku chitsulo, ndi chromium ndi faifi tambala monga zinthu zofunika alloying. Zinthuzi, pamodzi ndi zinthu zina zing'onozing'ono, zimapatsa zitsulo zosapanga dzimbiri 304 kuti zisamachite dzimbiri, ductility, komanso kutentha kwambiri. Kuphatikizika kwapadera kumeneku kumapangitsa pepala lachitsulo chosapanga dzimbiri la 304 kukhala zinthu zosunthika zomwe zimayenera kugwiritsidwa ntchito mosiyanasiyana.
