Te whakaputanga:
Ko te mea e kiia nei ko te maitai kore waikura takirua i roto i tana otinga totoka o te wāhanga ferrite me te austenite e tutuki ana i ia haurua, ko te tikanga he iti ake te ihirangi o te ihirangi me eke ki te 30%. Mena he iti te C, ko te ihirangi Cr he 18% ki te 28%, ko te ihirangi Ni he 3% ki te 10%. Kei roto hoki i ētahi maitai te Mo, Cu, Nb, Ti, N me ētahi atu huānga whakarewa.
Ngā Painga.
He rite ngā āhuatanga o te maitai ki te maitai kore waikura austenitic me te ferritic,
1. Ki te whakataurite ki te ferrite, he pai ake te kirihou, te pakari teitei, te kore pakarukaru i te pāmahana rūma, te ātete ki te waikura intergranular me te mahi whakarewa, me te pupuri tonu i te rino he pakarukaru maitai kore waikura 475 ℃ me te kawe wera teitei, me te superplasticity me ētahi atu.
2. Ki te whakatauritea ki te maitai kore waikura austenitic, kua tino pai ake te kaha me te ātete ki te waikura intergranular me te ātete ki te waikura ahotea chloride.
3. He tino pai te ātete o te maitai kore waikura takirua ki te waikura pakaru, engari he pai anō hoki te ātete ki te waikura nikara.
