Ko te 253MA (UNS S30815) he kowiri tira austenitic ātete-wera, i hangaia mō ngā mahi e hiahia ana ki te kaha ngoki me te ātete pai ki te waikura. Ko tōna awhe pāmahana mahi ko te 850~1100 °C.
He taurite te hanganga matū o te 253MA, ā, koia te mea e tino pai ai te mahi a te maitai i waenga i te 850°C ki te 1100°C, he tino teitei te ātete ki te waikura, tae atu ki te pāmahana waikura tae atu ki te 1150°C, ā, he tino teitei te ātete ki te ngokingoki. He kaha me te kaha pakaru ngokingoki; he tino pai te ātete ki te waikura pāmahana teitei me te ātete ki te waikura paraihe i roto i te nuinga o ngā mea hau; he teitei te kaha hua me te kaha kume i ngā pāmahana teitei; he pai te hanga me te whakarewa, ā, he nui te kaha miihini.
Haunga ngā huānga whakakoi ko te chromium me te nickel, he iti noa iho ngā konganuku whenua onge kei roto i te maitai kore waikura 253MA, ā, ka tino whakapai ake i tōna kaha ārai mate. Ka tāpirihia te hauota hei whakapai ake i ngā āhuatanga ngoki me te hanga i tēnei maitai kia tino austenite. Ahakoa he iti noa te ihirangi o te chromium me te nickel, he maha ngā āhuatanga pāmahana teitei o aua maitai kore waikura ki ngā maitai koranu tino whakakoi me ngā koranu turanga nickel.
