Ina pātai mai ngā kaihoko ki a mātou mō ngā mata wiri HSS, ko tētahi o ngā pātai e tino pātaihia ana ko: "He aha te rerekētanga i waenganui i te M42, te M35, te M2 — ā, me pēhea te 4341?"
He pātai tika tēnei. He rauemi maitai tere-teitei (HSS) katoa ēnei, ā, i te mata, he āhua ōrite tonu. Engari ko te momo e whiriwhiria e koe he pānga nui ki te roa o te ora o tō wiri, ki tōna mahi i raro i te wera, me te mea he tika mō te rauemi e tapahia ana e koe.
Anei tētahi whakamārama māmā.
He aha te HSS, ā, he aha te hiranga o te māka?
Ko te HSS he whakarāpopototanga mō te High-Speed Steel — he koranu maitai taputapu i hangaia hei tapahi i te konganuku i ngā tere teitei me te kore e ngaro tōna pakeke. Kāore i rite ki te maitai waro, ka mau tonu te mata tapahi o te HSS ahakoa ka wera i te wā e keri ana.
Engari kāore i te rite katoa ngā HSS. Ko te momo — M42, M35, M2, 4341, me ētahi atu — e pā ana ki te hanganga motuhake o te koranu. Ko ngā rerekētanga iti o ngā huānga pēnei i te tungsten, te molybdenum, te vanadium, me te cobalt ka arahi ki ngā rerekētanga nui o te mahi.
Kia mōhio: He rerekē te huarahi a te M42 i te M35 — he nui rawa te molybdenum e whakamahia ana, kaua ki te tungsten taumaha, e homai ana he pakari wera pai ake i te utu koranu kiato ake.
Ko te HRC teitei ake he pai ake te ātete ki te kakahu — engari he paku pakarukaru anō hoki. Ko te M42 te mea tino uaua, engari me whai tautuhinga pumau, pakari hoki kia kore ai e pakaru. Ko te 4341 te mea tino ngawari me te tino pakari, ā, he mea ngāwari te whakamahi whānui.
M42 — Te Tohu Mahi-Teitei mō ngā Konukōre Uaua
Kei te tihi o te taumata HSS te M42. Me te 8% o te cobalt me te nui rawa o te molybdenum (HS2-9-1-8, e mōhiotia ana ko HSSCo8, SKH59, P2M9K8, S500 rānei), kua hangaia mō ngā rauemi ka tere te pakaru o te wiri HSS paerewa.
Kei te kōrero tātou mō ngā koranu nikara, te taitaniuma, ngā maitai whakapakeke, ngā koranu tino ātete-wera — arā, ngā rauemi e whakawhirinakihia ana e te ao rererangi, te ao tiaki whenua, me te ao hanga matatau. Ka taea e M42 te whakahaere i ēnei mea nā te mea ka taea e ia te tu atu i ngā pāmahana neke atu i te 680°C me te pupuri tonu i te mata tapahi koi, pai.
Ko te painga, he pakarukaru ake te M42 i ngā momo i raro iho. He pai ake te mahi i roto i ngā whakatakotoranga pakari, whakahaeretia, e whakaitihia ai te wiri. He nui ake hoki te utu — engari mō te whakamahinga tika, ko te roa o te ora o te taputapu he mea tika.
M35 — Ina Keria Ana e Koe Ngā Rauemi Pakari
Ka tāpirihia e te M35 te 5% konupora ki te turanga M2 (nō reira te ingoa rerekē ko HSSCo5, ko HS6-5-2-5 rānei). Mā taua nui o te konupora ka tino whakanuia te ātete wera o te keri — tae atu ki te 630–650°C — ā, ka panaia te pakeke ki te 63–66 HRC.
Mō ngā kaituku e tuku ana ki ngā ahumahi pēnei i te motuka, te HVAC, te hanga māmā rānei — he wāhi noa te mahi maitai kore waikura — he whakapai ake atamai te M35 i te M2. He pakeke ake, he ātete ki te pakarukaru, ā, he roa ake te ora o te taputapu i roto i ngā āhuatanga uaua me te kore e pāngia e te pakarukaru o te M42.
Whakaarohia te M35 hei tino pai: he pai ake i te HSS paerewa, engari he whai hua tonu, he pono hoki i roto i te whānuitanga o ngā taiao awheawhe.
M2 — Te Paerewa e Whai Hua ana mō te nuinga o ngā Mahi
Ko te M2 te momo HSS e whakamahia whānuitia ana i te ao. Ko tōna ingoa katoa ko HS6-5-2 (e mōhiotia ana ko SKH51, ko P6M5 rānei), e whakaata ana i tōna hanganga: 6% tungsten, 5% molybdenum, 2% vanadium — kāore he cobalt.
Koinei te rauemi matua mō te keri whānui puta noa i te whānuitanga o ngā konganuku - te maitai ngawari, te konumohe, te parahi, te rino maka, me ētahi atu. He tino huri ngā keri M2, he rite tonu, ā, he iti te utu. Mō te nuinga o ngā taiao awheawhe me te hanga paerewa, ko te M2 tonu te mea e hiahiatia ana e koe.
Ki te kore te kaihoko e tohu i tētahi taumata, ko te M2 tonu te mea e whiwhi ana rātou — ā, mō te nuinga o ngā tono, he pai noa iho tēnā.
4341 — Te Kōwhiringa Taumata-Whakaurunga Pakari, Maha-Wāhi
Ko te 4341 (e tuhia ana ko W4Mo3Cr4VSi) he momo HSS tungsten-molybdenum e iti iho ana i te M2 i roto i te mahi, engari he tino pakari me te ātete ki te pānga. He tino rongonui i roto i ngā mākete e tino arohia ana te whai huatanga o te utu.
Ki te whakatauritea ki te M2, he iti ake te pakeke o te 4341, ā, he iti ake te pakeke wera — arā, kāore e pai te mau i ngā pāmahana tiketike. Engari mō te keri i ngā konganuku ngohengohe, i ngā mahi rānei e whakakapia pinepinetia ana ngā keri kaua e tiakina, ka oti pai te mahi me te whai hua.
He mea noa te 4341 mō ngā huinga mata keri kua tākaihia e hokona ana mā roto i ngā hongere hokohoko me ngā taputapu, he mea nui ake te utu i te mahi tino pai. Ehara i te mea koia te taputapu pai rawa atu mō ngā koranu pakari — engari mō ngā mahi māmā o ia rā, he tika te tūranga.
