I-253MA (i-UNS S30815) yintsimbi ye-austenitic enganyangekiyo ekwazi ukumelana nobushushu eyenzelwe usetyenziso olufuna amandla aphezulu okurhubuluza kunye nokumelana nokugqwesa okuhle. Umgangatho wobushushu osebenzayo yi-850 ~ 1100 °C.
Ukwakhiwa kweekhemikhali ze-253MA zilungelelene, okwenza ukuba intsimbi ibe neyona ndlela ifanelekileyo yokusebenza ngokubanzi kwiqondo lokushisa kwe-850 ° C-1100 ° C, ukuxhathisa okuphezulu kakhulu kwe-oxidation, ukushisa kwe-oxidation ukuya kwi-1150 ° C, kunye nokumelana nokunyuka okuphezulu kakhulu. Ukukwazi kunye namandla okukrazuka okurhubuluzayo; ukuxhathisa okugqwesileyo kubushushu obuphezulu kunye nokuxhathisa kwi-brashi ye-corrosion kwimithombo yeendaba ezininzi zegesi; amandla aphezulu esivuno kunye namandla okuqina kumaqondo obushushu aphezulu; formability elungileyo kunye weldability, kunye machinability ngokwaneleyo.
Ukongeza kwizinto ezidibanisa i-chromium kunye ne-nickel, i-253MA yensimbi engenasici ikwaqulethe ixabiso elincinci leentsimbi zomhlaba ezinqabileyo, ngaloo ndlela iphucula kakhulu umthamo wayo we-antioxidant. I-nitrojeni yongezwa ukuphucula iipropati ezikhasayo kwaye wenze le ntsimbi i-austenite ngokupheleleyo. Nangona imixholo ye-chromium kunye ne-nickel isezantsi kakhulu, iintsimbi ezinjalo ezingenasici kwiimeko ezininzi zineempawu ezifanayo zobushushu obuphezulu njengentsimbi yealloyi edibeneyo kunye ne-nickel base alloys.
