He aha te mata wiri HSS?
Ko te wiri hurihuri HSS he momo taputapu keri i hangaia ki te maitai tere-rahi e whakamahia ana mō te tukatuka konganuku. He maitai koranu motuhake te HSS me te ātete pai ki te pakū, te pumau wera, me ngā āhuatanga tapahi, he mea tino pai mō ngā mahi mahi konganuku pēnei i te keri. Ko te wiri hurihuri (e mōhiotia ana ko te wiri auger, ko te wiri putorino porowhita rānei) he wiri me ngā putorino porowhita e taea ai e ngā maramara tapahi te puta wawe i te poka keri, ka whakaiti i te waku me te wera i te wā keri me te whakapai ake i te pai o te keri. Nā te hoahoa o ngā wiri hurihuri HSS he mea pai mō te whānuitanga o ngā rauemi konganuku rerekē, tae atu ki te maitai, te konumohe, te parahi me ngā koranu, me ētahi atu, tae atu ki te miihini momo rakau.
Ngā Āhuatanga o ngā Wiri Miro Rino Tere-Tiketike
1. Te Ātete Nui ki te Waro: He tino pai te ātete o ngā rauemi maitai tere-teitei ki te ware, e āhei ai ngā mata tapahi kia koi tonu mō te wā roa.
2. Te Pūmautanga Wera Teitei: Ka taea e te maitai tere-rahi te mahi i roto i ngā taiao pāmahana teitei me te kore e ngaro te pakeke, te rerekētanga rānei.
3. Mahi Tapahi Tino Pai: Mā te hoahoa awaawa porowhita o ngā wiri hurihuri ka whai hua te tapahi whakarewa me te whakaiti i te kohikohinga maramara.
4. Te Kounga Mīhini Pono: Ko ngā wiri miro maitai tere-teitei e tuku ana i ngā kōhao kua keria kounga teitei me ngā ine tika me ngā mata maeneene.
Ngā Momo HSS i Whakamahia e Mātou mō ā Mātou Wiri Whakakorikori
Ko ngā momo matua o te HSS e whakamahia ana e mātou ko: M42, M35, M2, 4341, 4241.
He rerekētanga kei waenganui i a rātou, ko te nuinga e pā ana ki te hanganga matū, te pakeke, te pumau o te wera me ngā wāhi tono. Kei raro nei ngā rerekētanga matua i waenganui i ēnei tohu HSS:
1. M42 HSS:
Kei roto i te M42 te 7%-8% o te cobalt (Co), te 8% o te molybdenum (Mo) me ētahi atu koranu. Mā tēnei ka pai ake te ātete ki te pakū me te pumau o te wera. He nui ake te pakeke o te M42, ā, ko tōna pakeketanga toka he 67.5-70 (HRC) ka taea te whakatutuki mā ngā tikanga maimoatanga wera.
2. M35 HSS:
Kei roto i te M35 te 4.5%-5% konukōre, ā, he tino ātete ki te pakū me te pumau ki te wera. He mārō ake te M35 i te HSS noa, ā, he maha ngā wā ka mau tonu tōna mārō i waenga i te 64.5 me te 67.59 (HRC). He pai te M35 mō te tapahi i ngā rauemi piripono pērā i te maitai kore waikura.
3. M2 HSS:
Kei roto i te M2 he nui te tungsten (W) me te molybdenum (Mo) ā, he pai hoki ōna āhuatanga tapahi. Ko te pakeke o te M2 kei roto i te awhe 63.5-67 (HRC), ā, he pai mō te miihini i ngā konganuku e hiahia ana ki ngā whakaritenga teitei ake.
4. 4341 HSS:
He maitai tere-rahi te 4341 HSS, he iti ake te nui o te koranu i te m2. Ko te pakeketanga he mea pupuri tonu ki runga ake i te 63 HRC, ā, he pai mō ngā mahi whakarewa whānui.
5. 4241 HSS:
Ko te 4241 HSS he HSS koranu iti hoki, he iti ake ngā huānga koranu. Ko te pakeketanga e mau tonu ana i te 59-63 HRC, ā, e whakamahia ana mō te mahi whakarewa whānui me te keri.
Ko te whiriwhiri i te taumata tika o te HSS e whakawhirinaki ana ki ō hiahia me te momo rauemi e tukatukahia ana. Ko te mārō, te ātete ki te pakū me te pumau o te wera ngā mea matua o te whiriwhiri.
