Mawu Oyamba
Zitsulo zosapanga dzimbiri ndi zitsulo zokhala ndi aloyi wapamwamba kwambiri zomwe zimalimbana ndi dzimbiri kuposa zitsulo zina chifukwa cha kukhalapo kwa chromium yambiri yomwe ili pakati pa 4 mpaka 30%.Zitsulo zosapanga dzimbiri zimagawidwa kukhala martensitic, ferritic ndi austenitic kutengera mawonekedwe awo a crystalline.Mu addititon, amapanga gulu lina lodziwika kuti zitsulo zolimba-mvula, zomwe zimakhala ndi zitsulo za martensitic ndi austenitic.
Tsamba lotsatirali lipereka zambiri zazitsulo zosapanga dzimbiri 347H, zomwe ndi zolimba pang'ono kuposa zitsulo za grade 304.
