Mafotokozedwe Akatundu
Pambuyo powonjezera Ti ngati chinthu chokhazikika, zitsulo zosapanga dzimbiri 321 zimawonetsa mphamvu zotentha kwambiri, zomwe zili bwino kuposa 316L chitsulo.Imakhala ndi kukana kwabwino kwambiri mumitundu yosiyanasiyana ya organic ndi inorganic acid ngakhale mosiyanasiyana komanso kutentha.Kuphatikiza apo, chitsulo chosapanga dzimbiri cha Type 321 chimagwira ntchito bwino m'malo oxidizing.Izi zimapangitsa kukhala koyenera kupanga zotengera zolimbana ndi asidi, zomangira zida ndi mapaipi.
Kupangidwa kwa 321 chitsulo chosapanga dzimbiri kumaphatikizapo faifi tambala (Ni), chromium (Cr) ndi titaniyamu (Ti), yomwe ndi austenitic zosapanga dzimbiri aloyi.Zofanana ndi 304 zitsulo zosapanga dzimbiri zomwe zili ndi zinthu zofanana.Komabe, kuwonjezera kwa titaniyamu kumakulitsa kukana kwake kwa dzimbiri m'malire a tirigu ndikuwonjezera mphamvu yake pakutentha kwambiri.Kuphatikiza kwa titaniyamu kumalepheretsa mapangidwe a chromium carbides mu alloy.
321 Chitsulo chosapanga dzimbiri chili ndi zinthu zabwino kwambiri potengera kupsinjika kwa kutentha kwambiri komanso kukana kwamphamvu.Makina ake amakina pansi pa kutentha kwambiri amaposa zitsulo zosapanga dzimbiri 304.Choncho, ndi yabwino kuwotcherera ntchito zokhudza zigawo zikuluzikulu ntchito pa kutentha kwambiri.
