Dhererka: 30 mitir (ugu badnaan)
Habka farsamada: sawir qabow ama rogid qabow
Xaaladda dusha sare: dusha sare ee xalka adag; nadiifin farsamo; dahaarka dhalaalaya
Daawaynta dhammaadka: PE (af fidsan), BE (Bevel)
Baakadaha: bac tolmo leh oo la duubay / sanduuq alwaax ah / baakad sanduuq alwaax ah oo dhoofin ah
Faallooyin: Tuubo bir ah oo aan caadi ahayn oo aan caadi ahayn ayaa loo habeyn karaa iyadoo loo eegayo shuruudaha macaamiisha
253MA (UNS S30815) waa bir aan miridh lahayn oo u adkaysta kulaylka oo loogu talagalay codsiyada u baahan xoog sare oo gurguurta iyo iska caabin wanaagsan oo daxalka ah. Heerkulka shaqadeedu waa 850~1100 °C.
Halabuurka kiimikada ee 253MA waa mid isku dheelitiran, taasoo ka dhigaysa birtu inay leedahay waxqabadka ugu habboon ee dhammaystiran ee heerkulka 850°C-1100°C, iska caabin oksaydh oo aad u sarreeya, heerkulka oksaydheynta ilaa 1150°C, iyo iska caabin aad u sarreeya oo gurguurta. Awoodda iyo xoogga dillaaca gurguurta; iska caabin aad u fiican oo ku wajahan miridhka heerkulka sare iyo iska caabinta miridhka burushka ee inta badan warbaahinta gaaska; xoog wax soo saar sare iyo xoog jiidis heerkul sare; qaab wanaagsan iyo alxan, iyo mashiin ku filan.
Marka laga soo tago walxaha isku-darka chromium iyo nickel, birta aan daxalka lahayn ee 253MA waxa kale oo ku jira xaddi yar oo biraha dhulka naadirka ah, taasoo si weyn u hagaajinaysa awooddeeda ka-hortagga oksaydhka. Nitrogen ayaa lagu daraa si loo hagaajiyo sifooyinka gurguurta oo looga dhigo birtan mid gebi ahaanba austenite ah. Inkasta oo waxyaabaha ku jira chromium iyo nickel ay yihiin kuwo hooseeya, biraha aan daxalka lahayn ee noocaas ah waxay leeyihiin xaalado badan isla sifooyinka heerkulka sare sida biraha isku-darka ah ee aadka u daxalka leh iyo biraha salka nikkel.
