He mata parau ātete-mau, he mea hanga ki te maitai konupora 65Mn, he pai mō te parau i ngā mara.
E mōhio ana mātou ki ngā āhuatanga whakakoi o te oneone i runga i ngā konganuku. Ka whakamahia e tēnei hua te maitai konupora nui kawemai, te maitai puna koranu kounga teitei 60Si2Mn rānei hei rauemi turanga. Mā te tukanga maimoatanga wera tinei isothermal patent, ka eke te pakeke o te mata o te parau ki te HRC 48-52, ā, ka mau tonu te ngāwari me te pakari o te pūtake. Mā tēnei āhuatanga "pakeke ki waho, pakari ki roto" e kore e taea anake te mahi ngāwari i te parau i roto i te kirikiri me te whenua pakeke, engari ka ārai hoki i te pakaru, i te pakaru rānei i puta mai i te pā ki ngā mea pakeke i te wā e whakamahia ana, ka roa ake tōna ora ratonga mā te 50%-80% ki te whakaritea ki ngā parau noa.
Hoahoa whakangawari koiora: Ka arotauhia te piko o te pito koko i runga i te hihiri oneone, ka whakaitihia te ātete ki te parau me te kawenga kukume tarakihana, me te penapena wahie inehia o te 8%-12%.
Hangarau mata whakakoi-ake: I te ngaunga o te parau, ka mau tonu te koki āhua koi o te wāhanga mahi o te mata parau, kia pumau ai te hohonu o te parau me te papa awaawa maeneene, kore-taumata.
Te tūnga tika o te kōhao: Mā te whakamahi i te hangarau tūnga tapahi taiaho, ka whakahaerehia te ātete tawhiti o te kōhao tāutanga i roto i te ±0.5mm, ka uru pai ki te ringa parau taketake, ā, ka whakakorea katoatia te wiri me te haruru rerekē i puta mai i ngā āputa.
Ka hipokina e tēnei raupapa parau ngā parau papa pokepoke paerewa mai i te 1L-325 ki te 1L-535, ā, he hototahi hoki ki ngā parau hurihuri waipēhi kawemai mai i ngā waitohu pēnei i a Reckon (Tiamana) me Besson (Wīwī). Ahakoa he oneone whero taumaha, he oneone albic kua whakakīia, he whenua kua whakakīia rānei he iti nei te kirikiri, ka whakaatuhia e ngā parau he pai rawa te uru ki te oneone me te kaha ki te huri, ka eke ki te tere pakaru oneone neke atu i te 90%, ka hangaia he hanganga moenga purapura tino pai mōu.
