Chitsulo chosapanga dzimbiri
Chitsulo chosapanga dzimbiri ndi chitsulo chosapanga dzimbiri chokhala ndi chromium yochepera 10.5%.Pali magiredi osiyanasiyana komanso zomaliza zazitsulo zosapanga dzimbiri zomwe zimapangidwa kuti zigwirizane ndi malo omwe zinthuzo zidzagwiritsidwe ntchito.Mosiyana ndi chitsulo cha carbon, chitsulo chosapanga dzimbiri sichichita dzimbiri chikakhala ndi mpweya ndi chinyezi chifukwa cha kuchuluka kwa chromium komwe kulipo.Chromium imapanga filimu yosaoneka ya chromium oxide yomwe singalole mpweya kuwukira pamwamba ndikuletsa dzimbiri pazitsulo zachitsulo.

Zitsulo zosapanga dzimbiri zitha kugawidwa m'magulu 7:
Zitsulo Zosapanga dzimbiri za Ferritic
· Chromium ndiye gawo lawo lalikulu la aloyi
· Ductility ndi formability zochepa kuposa austenitic giredi
· Maginito
· Kusamva dzimbiri, kulimba kwambiri kuposa austenitic
· Sizingaumitsidwe ndi kutentha mankhwala
