He aha te pānga o te nui o te Cr me te C ki te ātete kakahu o ngā pereti ātete kakahu?
Ko te waro te huānga matua mō te hanga i ngā kāpira. I te aroaro o te Cr, ka honoa te waro ki te chromium hei hanga i ngā kāpira chromium (Cr₇C₃, Cr₃C₂, me ētahi atu). Ka nui ake te ihirangi waro, ka nui ake te ihirangi kāpira, ā, ka pai ake te mārō whānui o te rauemi me te ātete ki te kakahu.
He huānga matua te chromium mō te hanganga o ngā warowaiha mārō pumau, ā, he pai hoki te pumau i te pāmahana teitei me te ātete ki te waikura. I roto i te pūnaha Cr-tiketike, ka tipu poutū ngā tioata warowaiha chromium, ā, ka whakaritea poutū ki te ahunga o te kakahu, ka āwhina i te ātete ki ngā karawarawa me te kakahu pānga. Hei tāpiri, ka taea hoki e te Cr te whai wāhi ki te whakatikatika i te witi i roto i te whakarewa me te whakapai ake i te kiato o te whakaritenga.
I roto i te hoahoa, ko te ihirangi Cr e whakahaeretia ana i te nuinga o te wā ki te 18%~30%, ā, ko te ihirangi C kei waenga i te 3%~5%. Ka taea e tēnei ōwehenga te hanga i te nui o ngā warowaihā momo Cr₇C₃ kua tohatohahia kia ōrite, he pakeke teitei, he iti hoki te tauwehenga waku, e whakapai ake ana i te roa o te ora o te rauemi i raro i ngā āhuatanga pēhanga teitei me te pānga teitei.
