440C Rino me te Rino D2

Mō ngā maitai mahi-teitei mō ngā maripi, ngā taputapu tapahi, ngā peera, me ngā wāhanga tino tika,440C maitai kore waikuramemaitai taputapu D2e rua ngā kōwhiringa rongonui. E mōhiotia ana ngā rauemi e rua mō tō rātou pakeke, te ātete ki te kakahu, me te roa, engari he rerekē te hanganga, te ātete ki te waikura, te ngāwari ki te miihini, me te utu. He mea nui te mārama ki ngā rerekētanga i waenga i ēnei maitai kia taea ai e ngā miihini, ngā kaihanga, me ngā kaihoko te whakatau whakaaro nui mō te hoko.

I roto i tēnei tuhinga, ka tūhuratia e mātou ngā āhuatanga, ngā painga, ngā ngoikoretanga, me ngā whakamahinga pai rawa atu o te maitai 440C memaitai D2, me te whakamārama anō hoki me pēheasakysteele whakarato ana i ngā rauemi e rua hei whakatutuki i ngā whakaritenga ahumahi kanorau.

1. Whakataki ki te Rino 440C

He maitai kowiri tira martensitic waro-teitei te 440C, ā, he pai rawa te taurite o te pakeketanga, te ātete ki te waikura, me te ātete ki te kakahu. Nō te whānau maitai kowiri tira raupapa 400, ā, he maha ngā wā ka whakamahanahia kia eke ki te pakeketanga teitei.

Te Hanganga Matū (Tōhua):

• Waro: 0.95–1.20%

• Konupora: 16.0–18.0%

• Konupora: ≤1.0%

• Hiraka: ≤1.0%

• Molibdenum: 0.4–0.8%

Ngā Āhuatanga Matua o te Rino 440C:

• Te pakeketanga teitei (tae atu ki te HRC 58–60 i muri i te maimoatanga wera)

• He pai te ātete ki te waikura ki te whakataurite ki te nuinga o ngā maitai taputapu

• He ātete kakahu pai rawa atu

• He pai mō ngā tono kei reira te makuku me ngā matū ngawari

Ngā tono noa:

• Ngā mata maripi (ina koa mō ngā taiao o waho me te moana)

• Ngā taputapu pokanga

• Ngā peera hurihuri

• Ngā wāhanga takirere

• Ngā taputapu tapahi ahumahi

2. Whakataki ki te maitai D2

He maitai taputapu waro-nui, konupora-nui te maitai D2, e mōhiotia ana mō tōna ātete ki te kakahu me te pakari. E kiia ana he maitai haurua-waikura nā te mea he nui te ihirangi konupora, engari kāore e rite te ātete ki te waikura ki ngā maitai kore waikura tūturu pērā i te 440C.

Te Hanganga Matū (Tōhua):

• Waro: 1.40–1.60%

• Konupora: 11.0–13.0%

• Molibdenum: 0.7–1.2%

• Vanadium: 0.5–1.1%

• Konupora: ≤0.6%

Ngā Āhuatanga Matua o te maitai D2:

• He tino ātete ki te kakahu

• Te pakeketanga teitei (tae atu ki te HRC 60–62 i muri i te maimoatanga wera tika)

• He pai ake te pupuri i ngā taha i te 440C i roto i ngā tono whakamahinga maroke maha

• He iti ake te ātete ki te waikura ki te whakataurite ki ngā maitai kore waikura

Ngā tono noa:

• Ngā mate tapahi ahumahi

• Ngā pū me ngā taputapu hanga

• Ngā maripi taumaha

• Ngā mata kutikuti

• Ngā taputapu mō ngā kirihou me ngā konganuku

3. Te maitai 440C me te maitai D2: Ngā rerekētanga matua

3.1 Ātete ki te Waikura

• 440C:He nui ake te ātete ki te waikura nā te nui ake o te chromium (16–18%), ā, he pai mō ngā taiao makuku, ngā taiao waikura pakupaku rānei.

• D2:He pai te ātete ki te waikura me te poke, engari he iti iho i te 440C. Ka waikura pea mēnā ka roa te wā e pāngia ana e te makuku me te kore e tiakina tika.

Whakatau:Mō ngā taiao moana, mō ngā āhuatanga haumākū rānei, he pai ake te 440C.

3.2 Ātete ki te Mau

• 440C:He tino ātete ki te kakahu engari he iti iho i te D2 i ngā taiao maroke, taratara hoki.

• D2:He ātete pai ki te kakahu, inā koa i roto i ngā mahi taputapu e whakamahi ana i ngā rauemi mārō me te pānga auau.

Whakatau:Mō te ātete nui ki te kakahu i ngā āhuatanga mahi maroke, ka eke te D2 ki te taumata 440C.

3.3 Te Mārō me te Pupuri i te Tapa

• 440C:Ka taea te eke ki te HRC 58–60, ka mau tonu te koi o te mata mō te wā roa, engari kāore e roa pērā i te D2 ina tapahi taumaha.

• D2:Ka taea te whakatutuki i te HRC 60–62, ā, he maha ngā wā ka roa ake te koi nā te mea he nui ake te waro me ngā warowaiha vanadium.

Whakatau:Ko te tikanga he pai ake te pupuri mata o te D2 mō ngā taputapu tapahi taumaha.

3.4 Te Pakari

• 440C:He pakari pai, engari kāore i te rite te ātete ki te pānga ki ētahi maitai waro-iti.

• D2:He paku pai ake te pakari i te 440C, engari ka pakaru pea ina pāngia kinotia.

Whakatau:He rite tonu te taumata pakari o ngā mea e rua; e taunakihia ana kia whakamātauhia i runga i te tono motuhake.

3.5 Te Āheitanga ki te Mīhini

• 440C:He māmā ake te mīhini i te āhua whakamahana i te D2.

• D2:He uaua ki te mīhini nā te ātete nui ki te kakahu; me whakamahi taputapu motuhake.

Whakatau:He māmā ake te whakamahi i te 440C i roto i te mīhini, ā, ka whakaitihia ngā utu whakaputa i ētahi wā.

3.6 Te Maimoatanga Wera

• 440C:Me tino tika te maimoatanga wera hei whakatutuki i te pakeketanga me te ātete ki te waikura.

• D2:He pai te urupare ki te maimoatanga wera engari ka ngāwari te whakapohehe nā te nui o te waro i roto.

3.7 Ngā Whakaaroaro Utu

• 440C:He nui ake te utu i ētahi wā nā ngā āhuatanga o te kowiri tira.

• D2:He iti ake te utu mō ia taumaha engari ka nui ake pea ngā utu miihini.

4. Te Kōwhiri i waenganui i te Rino 440C me te Rino D2

I te wā e whiriwhiri ana i waenga i ēnei maitai e rua, whakaarohia ēnei mea e whai ake nei:

• Kōwhiria te 440C mēnā:

  • He mea nui te ātete ki te waikura

  • Ko te tono ka uru ki te makuku, ki ngā matū, ki ngā taiao moana rānei

  • Me ngāwari ake te mahi miihini e hiahiatia ana e koe

• Kōwhiria a D2 mēnā:

  • Ko te ātete ki te kakahu me te pupuri i te taha ngā mea matua

  • Ka whakamahia te taputapu i roto i ngā taiao maroke, i ngā taiao whakakoi rānei

  • Ko te pakeketanga nui e hiahiatia ana mō te tapahi me te hanga i ngā rauemi mārō

5. Ngā Akoranga Take Ahumahi

Akoranga Take 1: Kaihanga Maripi Moana

I whiriwhiria e te kaihanga maripi ruku te maitai kore waikura 440C nā te mea he tino ātete ki te waikura me te pakeke. Ko te mutunga iho he roa ake te ora o te hua i roto i ngā taiao wai tote.

Akoranga Take 2: Te Wheketere Tānga Whakarewa

I whiriwhiria e tētahi kaihanga taputapu tā te maitai D2 mō āna huinga mate, me te whakamahi i te ātete nui ki te kakahu hei whakaroa i te roa o te ora o te taputapu me te whakaiti i te auau o te whakakapinga.

6. Ngā Tohutohu Tiaki

Ahakoa te maitai e whiriwhiria, mā te tiaki tika ka roa ake tōna ora:

• Puritia kia maroke ngā taputapu ina kore e whakamahia

• Tāpirihia he hinu tiaki, he paninga rānei ina rongoatia mō te wā roa

• Āraia te pānga nui rawa atu ka pakaru pea

• Whakakoi i te wā tika kia mau tonu ai te whai huatanga o te tapahi

7. Whakamutunga

Ngā mea e rua440C maitaimemaitai D2he rauemi tino pai, kua whakamātauhia ngā mahi ahumahi me ngā mahi taputapu. Ko te kōwhiringa e whakawhirinaki ana ki te taurite i waenga i te ātete ki te waikura, te ātete ki te kakahu, te ngāwari ki te miihini, me te utu.

He maha ngā wā ka whiriwhiria e ngā kaihanga i roto i ngā ahumahi maripi, taputapu, me te peera te 440C mō ngā taiao e ngāwari ana ki te waikura, me te D2 mō te ātete ki te kakahu i roto i ngā āhuatanga maroke, koi. Mā te mārama ki ngā āhuatanga o ia mea, ka taea e ngā kaihoko te whiriwhiri i te maitai tika mō ā rātou hiahia.

Hei kaiwhakarato o te ao,sakysteele tuku ana i te maitai kore waikura 440C me te maitai taputapu D2 i roto i ngā momo āhua, tae atu ki ngā pereti, ngā pae, me ngā wāhanga mīhini-rite, kia pai ai te kounga me te ōrite mō ngā tono uaua.
