Ko te maitai e whakamahia ana i roto i te hanga o ngā peera slewing e wehea ana ki ngā momo e whā: 50Mn, 42CrMo, 20CrMnTi, me GCr15SiMn. Hei tātari i te ātete kakahu o ngā niho peera slewing, me whakakotahi ngā āhuatanga o te rauemi, ngā tukanga maimoatanga wera, me ngā horopaki tono. Ko te whakarāpopototanga e whai ake nei i runga i ngā mōhiohio e tika ana:

GCr15SiMn:He maitai waro-rahi te chromium, he pakeke 60-64HRC, he ātete pai ki te kakahu, ā, he pai ake te ātete ki te kakahu i te maitai GCr15, he pai mō te mahi kawenga nui. Ko te nui o te waro (1.05%) me te chromium (1.5%) ka hanga i ngā waro mārō, me te ātete kakahu e whā ngā wā i te 20CrMnTi, he pai mō ngā āhuatanga mahi ātete kakahu me te ātete ngenge. Kei roto i ōna mara tono ngā mīhini hangarau, ngā pou tuku waka, me ētahi atu.

20CrMnTi:Nō te rino waro-iti tēnei momo maitai, ā, ko tōna pakari mata ka whakapaitia mā te whakamahana me te tinei. Ka taea e ia te hanga i tētahi paparanga whakamahana pakari teitei ki runga i te mata o te niho, me te pupuri tonu i te pakari me te kaha o te uho. I muri i te whakamahana, ka taea e te pakari o te mata te eke ki te 58-64HRC, ā, ka mau tonu te pakari me te kaha o te uho, nō reira he pai te ātete ki te kakahu, he mea tino pai mō ngā āhuatanga mahi taumaha, tere-nui, pānga rānei, pērā i ngā peera slewing i roto i te mahi whakarewa, mīhini keri me ētahi atu mara.

42CrMo:Nō te maitai waro-waenga te maitai, ā, he maha ngā wā ka whiwhi i ngā āhuatanga miihini whānui mā te tinei me te whakamahana (tinei me te whakamahana pāmahana-tiketike), me te ātete kakahu taurite, he pai mō ngā āhuatanga me ngā kawenga taurite, ā, kāore he pānga kino. Heoi, ki te whakaritea ki te maitai waro-iti i tukinotia ki te waro-whakarewa, tera pea he iti ake te ātete kakahu o te mata. He pai ake hoki te pumau me te kaha ngenge o te 42CrMo, he pakeke ake te mata, he pai mō ngā taiao kakahu teitei. He pai ake te 42CrMo mō te hanga.ngā peera patu,he pai te kaha whakaputa me te pakari, ka taea te tu atu i ngā kawenga me ngā pānga teitei, ā, he pai hoki mō te whakahaere roa o ngā mīhini hanga. I muri i te tinei, te whakamahana rānei i ēnei rauemi, ka taea te whakarite kia pumau te mahi a ngā niho i te wā e whakamahia ana mō te wā roa, ā, he mea noa te whakamahi hei peera whiu mō ngā mīhini taumaha, ngā kerēne nui, me ētahi atu taputapu.

50Mn:He momo maitai waro konupūmā tēnei e whakamahia whānuitia ana i roto i ngā mahi e hiahia ana kia kaha te pakari me te ātete ki te pānga, engari he toharite tōna ātete ki te kakahu, ā, ka taea te whakatutuki i ngā whakaritenga kaha me te ātete kakahu o ngā niho whīra whānui. He maha ngā wā ka tukuna te maitai konupūmā ki te maimoatanga wera (pēnei i te tinei) hei whakanui ake i tōna pakeke, engari he iti iho tōna pakeke mata i te 20CrMnTi kua rongoatia ki te carburizing, ā, kāore pea e rite te pumau o tana mahi ki te maitai koranu i roto i ngā taiao kakahu taumaha. Ka taea e te pakeke o te mata niho te eke ki te 50-60HRC, e pai ai mō ngā whīra whīra i raro i ngā kawenga tikanga me ngā tikanga mahi.

Te whakatauranga ātete kakahu: I te nuinga, ko te GCr15SiMn te ātete kakahu pai rawa atu, ko te 42CrMo me te 20CrMnTi he ātete kakahu pai anō hoki i muri i te whakakākahu me te tinei. Ko te ātete kakahu e whakawhirinaki ana ki te paparanga whakakākahu, ā, he ngāwari ki te kakahu i muri i te whakamahinga roa; He ngoikore te ātete kakahu o te 50Mn. I te wā e whiriwhiri ana, me whai whakaaro hoki ki ngā āhuatanga whakahaere motuhake (pēnei i te kawenga, te tere, te auau pānga) me te arotautanga o ngā tukanga maimoatanga wera. 

Mō ngā wāhanga matua pēnei i ngā niho whīra, mēnā me whai whakaaro ki te ātete kakahu me te ātete pānga, he pai ake te 42CrMo, me te kaha taurite, te pakari, me te ātete kakahu; mēnā me taurite te pakari teitei me te ātete pānga, ā, i raro i ngā tikanga mahi kawenga noa, he kōwhiringa pai hoki te 50Mn.

I roto i ngā mahi whaihua, me whai whakaaro whānuitia ngā āhuatanga pēnei i ngā tikanga whakahaere taputapu, te rahi o te kawenga, te tere, te taiao mahi, me te whakakotahitanga me te hangarau maimoatanga wera kia tutuki ai ngā whakaritenga hoahoa i te kōwhiringa rauemi o ngā niho amo.
