Ko ngā pereti maitai ātete-kakahu he mea hanga mai i tētahi pereti maitai waro-iti me tētahi paparanga ātete-kakahu koranu, ko te paparanga ātete-kakahu koranu he 1/3 ki te 1/2 o te matotoru katoa. I te wā e whakamahia ana, ka whakaratohia e te rauemi turanga ngā āhuatanga whānui pēnei i te kaha, te pakari, me te ngāwari hei ātete i ngā kaha o waho, ko te paparanga ātete-kakahu koranu he ātete-kakahu e hāngai ana ki ngā āhuatanga mahi motuhake.
Ka honoa te paparanga ātete-kakahu o te koranu me te rauemi turanga ki te konganuku. Mā te whakamahi i ngā taputapu motuhake me te tukanga whakarewa aunoa, ka honoa ōrite te waea koranu pakeke-teitei, ā-whaiaro ki te rauemi turanga. Ka taea te paparanga hiato te kotahi, te rua, te maha rānei o ngā paparanga. Nā te rerekētanga o ngā ōwehenga whakaheke koranu, ka puta ngā kapiti whakawhiti ōrite i te wā o te tukanga whakapiri, he tohu tēnei o ngā pereti maitai ātete-kakahu.
Ko te paparanga ātete-mau o te koranu he mea hanga tuatahi ki te koranu chromium, me ētahi atu huānga koranu pērā i te manganese, te molybdenum, te niobium, me te nickel kua tāpirihia. He muka ngā waro i roto i te hanganga whakarewa, ā, ko ngā muka e anga poutū ana ki te mata. Ka taea e te pakeketanga moroiti o te waro te eke ki runga ake i te HV 1700-2000, ā, ka taea e te pakeketanga o te mata te eke ki te HRC 58-62. He tino pumau ngā waro koranu i ngā pāmahana teitei, e mau tonu ana te pakeketanga teitei me te ātete pai rawa atu ki te waikura, e āhei ai te mahi katoa i roto i ngā pāmahana tae atu ki te 500°C.
Ka puta te paparanga ātete-kakahu i roto i ngā tauira whaiti (2.5-3.5mm) whānui rānei (8-12mm), me ngā tauira piko (S me te W). He mea hanga te nuinga mai i ngā koranu chromium, kei roto hoki i ēnei koranu te manganese, te molybdenum, te niobium, te nickel, me te boron. Ka tohatohahia ngā carbide i roto i te tauira muka i roto i te hanganga whakarewa, me ngā muka e rere poutū ana ki te mata. Mēnā he 40-60% te nui o te carbide, ka taea e te pakeke moroiti te eke ki runga ake i te HV1700, ā, ka taea e te pakeke o te mata te eke ki te HRC58-62. E toru ngā wāhanga matua o ngā pereti maitai ātete-kakahu: te ātete-whānui, te ātete-pānga me te ātete-mahana teitei. Ka taea e te matotoru katoa o ngā pereti maitai ātete-kakahu te iti ki te 5.5 (2.5+3) mm me te matotoru ki te 30 (15+15) mm. Ka taea te huri i ngā pereti maitai ātete-kakahu hei hanga i ngā paipa ātete-kakahu me te diameter iti rawa o te DN200, ā, ka taea hoki te tukatuka hei tuke ātete-kakahu, hei tī ātete-kakahu me hei whakaiti ātete-kakahu.
