Puna Mīhini Ahuwhenua Puna Kāri Āhua-S 12 * 45 Ngā Wāhanga Mīhini Ahuwhenua Ngā Taputapu Mīhini Ahuwhenua Puna Para me te Rake
Ko te puna momo-S (tauira: 12x45) he taputapu ngongo-whakakoi whakarewa i hangaia mō ngā mīhini ahuwhenua hou, e whakamahia whānuitia ana i roto i ngā mīhini parau whenua, ngā mīhini wetewete oneone, ngā mīhini wetewete hohonu, me ngā mīhini parau whenua me te whakarite whenua. Hei taputapu matua e hono ana i ngā wāhanga parau whenua (pēnei i ngā pito o te koko me ngā tokotoko taputapu) ki te anga, he mahi nui tāna ki te "ārai ngāwari" i te wā o te mahi parau whenua me tōna hanganga pihi āhua-S ahurei. Ka whakaratohia e tēnei hua he kaha whakaora whakarerekētanga pai me te whakarite i te pakari o te oneone mā te hoahoa āhuahanga kua arotauhia, he taurangi nui tēnei mō te tiaki i ngā mīhini ahuwhenua nui mai i te kino o te pānga pakari i raro i ngā āhuatanga whenua uaua.
Taupū pakeke: Ko te pakeke o te wāhi mahi kei waenganui i te HRC 42-48, e whakarite ana i te ātete ki te kakahu me te karo i te tūponotanga o te whati i puta mai i te pakarukaru nui.
Te maimoatanga mata: mā te whakamahi i te peita rehu, te peita rehu, te maimoatanga hiko rānei, he tino ātete ki te waikura me te waikura, ā, ka taea te urutau ki te haumākū tiketike me te taiao oneone ahuwhenua pH teitei.
Tauira/rahi hua: 12x45 (e pā ana ki te whānui whakawhiti-wāhanga rauemi o te 12mm, me ngā tawhā roa tāutanga, koki rānei e ai ki ngā paerewa raupapa 45).
Te hanganga rauemi: Ko te 65Mn (te maitai konupūmā 65) te 60Si2Mn rānei (te maitai puna konupūmā silicon) te rauemi matua. He momo maitai motuhake ēnei rauemi e rua mō te hanga puna, he tino teitei ngā rohenga pūmau me te ātete ki te ngenge.
Tukanga maimoatanga wera: Whai muri i te tinei me te whakamahana tika, ka whakarite kia whiwhi te hua i tētahi hanganga martensite whakamahana ōrite.
Te kaha ki te whakatauira me te karo i ngā arai: Ina tūtaki ki ngā mea pakeke (pērā i ngā toka, ngā pakiaka rākau) me ngā whenua pōkarekare i te wā e mahi ana i te mara, ka whakamahia e te puna āhua-S tōna āhua pīngore hei akiaki i te pito o te koko kia hiki ake, kia hoki whakamuri rānei, ka tere te tautuhi anō i muri i te karo i ngā arai. Mā tēnei āhuatanga "hoatu me te whakahoki" ka whakaiti i te tūponotanga o te piko, te whati rānei o ngā niho me te anga o te koko nā te pānga.
Ngā pānga o te pakaru oneone me te wiri: I raro i te whakahaere tere-teitei, ka puta he wiri pūmau auau-teitei me te iti te kaha o ngā puna āhua-S. Ka tukuna tēnei wiri ki te oneone mā te pito o te koko, ka taea te kuru i ngā poraka oneone nui kia rua ngā wā, me te whakaiti i te piri me te kohikohinga o te oneone ki te pito o te koko, ka whakaiti nui i te ātete ki te parau, ā, ka penapena i te whakapaunga wahie o te tarakihana.
Ngā rauemi kounga teitei me te roa o te ora: He mea hanga ki te maitai koranu 65Mn/60Si2Mn, kua tirotirohia te paparanga tango waro me te whakamātautau roa o te ora o te ngenge. I raro i ngā āhuatanga ahuwhenua noa, ka taea e tēnei puna te tu atu i ngā tekau mano o ngā piko hurihuri me te kore e whakarerekē tonu, e whati rānei, ā, he nui ake te roa o tōna ora ratonga i tō te rino noa, i ngā puna kāore anō kia rongoatia rānei.
