Whakaahuatanga Poto:
Pae Papatahi UNS S44000, Pae Papatahi SS 440, Kaiwhakarato Pae Papatahi Kowiri tira 440, Kaihanga me te Kawemai i Haina.
Ko ngā maitai kore waikura he maitai koranu teitei, he ātete teitei ki te waikura ki ētahi atu maitai nā te nui o te chromium. I runga i tō rātou hanganga tioata, ka wehea kia toru ngā momo pēnei i te maitai ferritic, austenitic, me te martensitic. Ko tētahi atu rōpū maitai kore waikura ko ngā maitai whakapakeke-waikura. He huinga ēnei o ngā maitai martensitic me te austenitic. Ko te maitai kore waikura taumata 440C he maitai kore waikura martensitic waro teitei. He kaha teitei, he ātete waikura taurite, ā, he pai te pakeke me te ātete kakahu. Ka taea e te taumata 440C te whakatutuki, i muri i te maimoatanga wera, te kaha teitei, te pakeke me te ātete kakahu o ngā koranu koranu katoa. Ko tōna ihirangi waro teitei te take o ēnei āhuatanga, e tino pai ai te 440C mō ngā tono pēnei i ngā peera pōro me ngā wāhanga takirere.
