253MA (UNS S30815) ndi chitsulo chosapanga dzimbiri cha austenitic chosagwira kutentha chomwe chapangidwira ntchito zomwe zimafuna mphamvu zambiri zoyenda komanso kukana dzimbiri. Kutentha kwake kogwira ntchito ndi 850~1100 °C.
Kapangidwe ka mankhwala ka 253MA ndi koyenera, zomwe zimapangitsa kuti chitsulocho chikhale ndi magwiridwe antchito abwino kwambiri pa kutentha kwa 850°C-1100°C, kukana kwambiri okosijeni, kutentha kwa okosijeni mpaka 1150°C, komanso kukana kwambiri kokosijeni. Mphamvu ndi kulimba kwa kuphulika kwa kukosijeni; kukana bwino kwambiri kukosijeni ndi kukana kokosijeni pa kutentha kwakukulu m'malo ambiri opangidwa ndi mpweya; mphamvu yogwira ntchito kwambiri komanso mphamvu yokoka pa kutentha kwakukulu; kupangika bwino komanso kusinthasintha, komanso makina okwanira.
Kuwonjezera pa zinthu zosakaniza chromium ndi nickel, chitsulo chosapanga dzimbiri cha 253MA chilinso ndi zitsulo zochepa zapadziko lapansi, motero zimawonjezera mphamvu yake yolimbana ndi ma antioxidants. Nayitrogeni imawonjezedwa kuti ikonze mphamvu zoyambira ndikupangitsa chitsulochi kukhala austenite kwathunthu. Ngakhale kuti chromium ndi nickel zili zochepa, zitsulo zosapanga dzimbiri zotere nthawi zambiri zimakhala ndi mphamvu zofanana ndi zitsulo za alloy zosakanikirana kwambiri komanso zitsulo za nickel base.
