He maitai kowiri tira te pereti maitai he maeneene te mata, he kaha ki te whakarewa, he ātete ki te waikura, he kaha ki te whakakanapa, he ātete ki te wera, he ātete ki te waikura me ētahi atu āhuatanga. He whānuitia te whakamahinga i roto i ngā momo ahumahi, ā, he rauemi nui i roto i ngā ahumahi hou. E ai ki te āhua hanganga, ka wehea te maitai kowiri tira ki te maitai kowiri tira austenitic, te maitai kowiri tira ferritic, te maitai kowiri tira martensitic, me te maitai kowiri tira takirua.Kowiri tira Austenitic: he kowiri tira me te hanganga austenitic i te pāmahana rūma. Kei roto i te maitai te Cr≈18%, Ni≈8%-25% me te C≈0.1%. He pakari me te kirihou te maitai, engari he iti te kaha.Kowiri tira MartensiticHe maitai ka taea te whakarerekē i ōna āhuatanga hangarau mā te whakamahana. He rerekē tōna kaha me tōna pakari i ngā pāmahana rerekē.Kowiri tira takiruaKo te Austenitic me te ferrite te haurua o te hanganga. Ina iti te ihirangi C, ko te ihirangi Cr he 18% ki te 28%, ā, ko te ihirangi Ni he 3% ki te 10%. Kei roto hoki i ētahi maitai ngā huānga whakarewa pēnei i te Mo, Cu, Si, Nb, Ti, me te N. He rite ngā āhuatanga o tēnei momo maitai ki te maitai kore waikura austenitic me te ferritic.Kowiri tira FerriticKei roto ko te 15% ki te 30% te chromium, ā, he hanganga karaihe poraka kei waenganui i te tinana. Kāore he nikara i roto i tēnei momo maitai, ā, i ētahi wā he iti noa te Mo, Ti, Nb me ētahi atu huānga kei roto. Ko ngā āhuatanga o tēnei momo maitai he kawe wera nui, he iti te tauwehenga whānui, he pai te ātete ki te waikura, me te ātete pai ki te waikura ahotea.
