He mata parau hurihuri, he ātete ki te pakaru, he matotoru hoki, he pai mō te parau me te tango i ngā kakau.
He mea hanga ēnei mata parau ahuwhenua kounga teitei mai i te maitai puna kounga teitei, me te mata i whakamahanahia kia tino ātete ki te pakaru. Mā te hoahoa pūtaiao ka taea te parau hohonu, te kapi pai, me te mata maeneene, ōrite i muri i te whakamahinga. He hototahi ki ngā momo mīhini ahuwhenua, he pakari te hurihanga, he ātete ki te whakarerekētanga, ā, he pai te whakaiti i te whakapaunga wahie, ka waiho hei whiringa pono mō ngā mahi ahuwhenua mīhini.
1. Maitai koranu kounga teitei: Ka āta whiriwhiria e mātou ngā maitai puna motuhake e tika ana mō ngā āhuatanga pānga nui me te kakahu nui, tae atu ki ngā maitai hanganga koranu kounga teitei pērā i te 60Si2Mn (60 silicon-manganese), 60Si2MnA, me te 28MnSiB. He tino teitei ngā pūwāhi tuku me ngā rohe ngāwari o ēnei rauemi, e āhei ai rātou ki te pupuri i te tinana taputapu me te kore e rerekē te āhua, e whati rānei i raro i te wiri nui me te taipana nui.
2、Hangarau whakamahana: Ka whakamahia he tukanga tinei martensitic, me te whakahaere pakari i te pāmahana whakamahana me te tere whakamatao kia tutuki ai te hanganga whakarewa tino pai o te mata. Ka whakahaeretia te pakeke o te hua kua oti i roto i te awhe pakeke Rockwell (HRC) o te 42-48, me ētahi whakatakotoranga e eke ana ki te HRC45±3. Mā tēnei awhe pakeke ka taea e te mata o te mata te tapahi ngāwari ki te oneone pakeke, ā, he tino ātete ki te kakahu, me te pupuri tonu i te pakari o te papa o te mata kia kore ai e pakaru.
Te whakaora i te koraha: Nā tōna kaha ki te uru ki te oneone, ka taea e ia te mahi tika ki runga i te koraha kua kikīhia, ka wawahi i te para parau mārō.
Te whakahaere taru me te rakau iti: Ka tapahia e ngā mata koi ngā pakiaka taru me ngā kakau rakau iti, ka ārai i te hononga me te aukati.
Mahi maha-mahi: Haunga te whakaora i te koraha, he pai hoki mō te parau hohonu, te tango i ngā kakau witi, me te tapahi i ngā tarutaru maroke i ngā mara kua pakeke, he nui te whakamahinga me te maha o ngā mahi.
