253MA (UNS S30815) waa bir aan lahayn austenitic kulayl u adkaysta oo loogu talagalay codsiyada u baahan xoog gurguurta oo wanaagsan iyo iska caabin daxalka wanaagsan.Heerkulka uu ku shaqeynayo waa 850 ~ 1100 ° C.
Halabuurka kiimikada ee 253MA waa dheellitiran, taas oo ka dhigaysa birta inay leedahay waxqabadka ugu habboon ee ugu habboon heerkulka heerkulka 850 ° C-1100 ° C, caabbinta oksaydhka oo aad u sarreeya, heerkulka oksaydhka ilaa 1150 ° C, iyo iska caabin aad u sarreeya.Kartida iyo xoogga dillaaca gurguurta;iska caabin heer sare ah oo u adkaysta daxalka heerkulka sare iyo caabbinta daxalka buraashka ee inta badan warbaahinta gaaska;xoogga wax-soo-saarka sare iyo xoogga xajinta heerkulka sare;qaabayn wanaagsan iyo weldability, iyo mashiin ku filan.
Marka lagu daro walxaha alloying chromium iyo nikkel, 253MA ahama birta sidoo kale ka kooban qadar yar oo biraha dhulka dhif ah, taas oo si weyn u hagaajinaysa awooddeeda antioxidant.Nitrojiin ayaa lagu daraa si loo hagaajiyo guryaha gurguurta oo ay birtan si buuxda u austenite ka dhigto.Inkasta oo maadada chromium iyo nikkelku ay aad u hooseeyaan, birta aan-daawaynta lahayn ee noocan oo kale ah waxay leeyihiin xaalado badan oo isku mid ah sifooyinka heerkulka sare sida birta daawaha ah ee aadka u daawaha ah iyo alwaaxyada saldhigga nikkel.
