He maitai waro-teitei te maitai kore waikura 440C, he maitai martensitic waro-teitei. He kaha teitei, he ātete ki te waikura taurite, ā, he pakari me te ātete ki te kakahu.
Whakaaturanga Ratonga Kotahi mō ngā Pereti Kowiri tira 440C:
Mō te pereti maitai kore waikura 440C, e pā ana ki tētahi wahi whakarewa papatahi i hangaia mai i te maitai kore waikura 440C. He maha ngā whakamahinga o ēnei pereti i roto i ngā mahi hanga me ngā mahi ahumahi e hiahiatia ana he taumata teitei o te pakeke me te ātete ki te waikura. Ka rerekē pea ngā rahi me ngā whakaritenga o te pereti i runga i ngā whakaritenga motuhake o te mahi. E mōhiotia ana te maitai kore waikura 440C mō tōna kaha ki te whakamahana kia teitei ake te pakeke i ngā taumata paerewa 440, pērā i te 440A me te 440B. Ka taea e tēnei whakamahana te whakarei ake i ōna āhuatanga miihini, tae atu ki tōna pakeke me te ātete ki te kakahu.
