He hua parau pakari tēnei, ātete ki te pakaru, e tika ana mō te mahi ahuwhenua o ēnei rā. Hei wāhanga matua o ngā parau whenua, ngā parau hurihuri waipēhi, me ngā parau whao, ka pā tika tōna kounga ki te whai huatanga o te mahi me ngā utu whakahaere. He mea hanga motuhake mō ngā taiao oneone uaua, he whānui te whakamahinga o tēnei hua ki ngā mīhini mahi whenua maha e honoa ana ki ngā tarakihana, ā, he mea pai mō te mahi whenua hohonu, te mahi keri whenua, te keri awaawa, me te tango otaota.

Ka whakamahia e te hua ngā rauemi koranu kaha-teitei o te ahumahi pērā i te maitai manganese 65Mn, te maitai boron rānei, kia kore ai e ngāwari te whakapē, te pakaru rānei i raro i te pānga pēhanga teitei.

Ka whakamahia e mātou te hangarau hanga wera matatau me te hangarau maimoatanga wera isothermal hei whakatutuki i te taumata rahi o te kōhao o roto o te 8, kia mau tonu ai te pakeke me te kaha o te pānga. Ko ētahi tauira papai he ātete ki te kakahu me te pakeke o te mata tapahi kāore i raro i te 62 HRC, e hanga ana i te āhuatanga "pakari ki waho, pakari ki roto", e whakaroa ana i te whakapōuri o te mata tapahi.

Te ātete kakahu teitei: Mā te whakahaere tika i te tukanga maimoatanga wera, ka whakahaerehia te pakeke o ngā hua i waenga i te HRC 38-53 (i runga i te tauira). Ko te ātete kakahu he nui ake i te 3 ngā wā i ērā o ngā hua noa i te mākete, ā, ka whakatau pai i te raruraru "poto te ora" i puta mai i te nui o te quartz i roto i te oneone.

Hoahoa whakakoi-ake: Mā te whakamahi i te hangarau whakarewa hiato matatau, ka mau tonu te koi o te pito parau ahakoa te rerekētanga o te kakahu i ngā paparanga rauemi rerekē i te wā e whakamahia ana, ka whakaitihia te ātete ki te parau, ā, ka whakaitihia te whakapaunga wahie o te tarakihana, ka hua ake he penapena pūngao me te atawhai ki te taiao.

Hoahoa Hurihuri/Whakataurite: Ko ētahi tauira he hoahoa hurihuri-rua. Ina tawhito tetahi pito, ka taea te huri, ā, ka taea te whakamahi i tetahi atu pito, ka tutuki ai te "roa rua" me te whakaiti nui i ngā utu whakakapinga me te wā kore mahi.

Ahakoa e whakamahia ana mō te parau i te kōanga, te ngaki raumati, te parau hohonu rānei i te ngahuru, he tino pai te mahi a tēnei mata parau. He tino pai mō ngā oneone kua whakakīia, ngā oneone uku taumaha, me ngā wāhi kōhatu kei roto he kirikiri, ka pakaru pai te papa parau, ka whakapai ake i te hau me te pupuri wai o te oneone, ā, ka whakatakoto i te turanga pakari mō ngā hua nui o te hua.
