Ko te whiriwhiri i te maitai taputapu tika tētahi o ngā whakataunga tino nui i roto i te hoahoa me te mahi o ngā pokepokea me ngā mate e whakamahia ana i roto i ngā mahi pāmahana teitei pēnei i te maka mate, te hanga, me te whakaputa. I roto i ngā momo momo e wātea ana,AISI H12meAISI H13Ko ētahi o ngā kōwhiringa rongonui e rua o te whānau maitai taputapu mahi wera.
I hangaia ngā maitai e rua mō te ātete wera nui, te kaha, me te pakari, engari he āhuatanga motuhake kei a rāua e pai ai ia mō ngā tono motuhake. I roto i tēnei tuhinga,SAKYSTEELKa tātarihia ngā rerekētanga matua i waenga i te AISI H12 me te H13, hei āwhina i a koe ki te whiriwhiri tika mō ō whakaritenga hanga pokepokea me ngā taputapu.
1. Kupu Whakataki: Te Hiranga o te Kōwhiri i te Rino Mahi Wera Tika
Kua hangaia ngā maitai taputapu mahi wera hei pupuri i te kaha me te pakeke o te miihini ahakoa i raro i ngā āhuatanga kino o te pāmahana teitei me te kawenga wera hurihuri. I roto i ngā ahumahi pēnei imakahanga mate, te hanga wera, mete whakaputanga, mā te kōwhiringa rauemi hē ka pakaru, ka pakaru wawe, ka hē rānei te āhua—ka nui te utu mō te wā kore mahi me te pakaru o te pokepokea ai.
Nō reira, te mārama ki ngāngā rerekētanga i waenga i te AISI H12 me te H13he mea tino nui hei whakatutuki i te taurite pai i waenga i te pakari, te ātete ki te kakahu, me te mahi ngenge wera.
2. Tirohanga Whānui o te AISI H12 me te AISI H13
Ngā mea e ruaAISI H12meAISI H13nō te raupapa-H AISI o ngā maitai taputapu mahi wera, arā, he maitai i ahu mai i te chromium e mōhiotia ana mō tō rātou kaha ki te ātete ki te whakangawari i ngā pāmahana tiketike.
-
AISI H12 (UNS T20812)He maitai chromium-molybdenum-tungsten e tuku ana i te ātete tino pai ki te ngenge wera me te pakari teitei.
-
AISI H13 (UNS T20813)He maitai chromium-molybdenum-vanadium he nui ake te ātete ki te kakahu me te pakeke whero pai, e kiia ana ko te paerewa ahumahi mō ngā pokepokea ai.
E whakamahia whānuitia ana ēnei maitai e rua, engari he rerekē te mahi a ō rātou huānga whakarewa motuhake, ā, he pai ake ai mō ngā momo pokepokea me ngā āhuatanga whakahaere rerekē.
3. Whakataurite i te Hanganga Matū
Ko te rerekētanga matua i waenga i te AISI H12 me te H13 kei roto i te hanganga o te koranu, e pā tika ana ki te pakeke, te pakari, me te ātete wera.
| Huānga | AISI H12 (%) | AISI H13 (%) | Pānga ki te Mahi |
|---|---|---|---|
| Waro (C) | 0.35–0.45 | 0.35–0.40 | Whakahaere i te pakeketanga me te ātete ki te kakahu |
| Konukōmiuma (Kr) | 4.75–5.50 | 4.75–5.50 | Whakapai ake i te ātete ki te waikura me te waikura |
| Molibdenuma (Mo) | 1.10–1.75 | 1.00–1.50 | Ka whakarei ake i te pakari me te mārō |
| Tungsten (W) | 1.00–1.75 | — | Ka whakanui ake i te kaha wera me te pakeke whero |
| Vanadium (V) | 0.20–0.60 | 0.80–1.20 | Ka whakapai ake i te hanganga o te witi, ka whakanui ake i te ātete ki te kakahu |
| Hiraka (Si) | 0.80–1.20 | 1.00 | Whakapai ake i te ātete waikura me te pumau o te pakeketanga |
| Manganēhi (Mn) | 0.25–0.50 | 0.30–0.50 | Whakapai ake i te pakari me te mārohirohi |
Ngā mea matua hei ako:
Kei roto i te AISI H12tungsten (W), e whakarato ana i te kaha wera me te pakari teitei, ko te AISI H13 ia hevanadium teitei ake (V)te ihirangi, te whakapai ake i te ātete ki te kakahu me te pakeke i ngā pāmahana tiketike.
4. Te Whakataurite i ngā Āhuatanga Mīhini
He pai te mahi a ngā maitai e rua i raro i ngā āhuatanga mahi wera, engari he rerekē te hiranga o ia maitai i ngā āhuatanga miihini.
| Taonga | AISI H12 | AISI H13 |
|---|---|---|
| Kiato | 7.80 karamu/cm³ | 7.80 karamu/cm³ |
| Pakari (Kua whakawerahia) | ≤ 229 HB | ≤ 229 HB |
| Te Pakari (I Muri i te Whakapakari me te Whakamahana) | 44–52 HRC | 46–54 HRC |
| Kaha Kume | 1500–1900 MPa | 1600–2000 MPa |
| Ātete ki te Ngenge Wera | Tino pai | Tino pai |
| Ātete Kakahu | Teitei | Tino Teitei |
| Te Pakari o te Pānga | Tino pai | Tino Pai |
| Te āheinga ki te mīhini | Pai | Waenga |
AISI H12ngā tuku pai akepakari pāngame te ātete ki te pakaru, i te wāAISI H13whakarato i te pai akete ātete ki te kakahu o te mataā, he paku teitei ake te pupuri i te mārō i te wā e roa ana te wā e werahia ana.
5. Ngā Āhuatanga o te Maimoatanga Wera
He mea nui te maimoatanga wera ki te whakatau i te mahi whakamutunga o ngā maitai e rua.
Maimoatanga Wera AISI H12
-
Te whakamahana:850–900°C, puhoi te whakamatao i te oumu
-
Te whakapakeketanga:1000–1050°C, tinei i te hau, i te hinu rānei
-
Te whakamahana:500–650°C (me whakamātao takirua te tūtohutanga)
Maimoatanga Wera AISI H13
-
Te whakamahana:850–900°C, puhoi te whakamatao i te oumu
-
Te whakapakeketanga:1020–1040°C, tineia i te hau
-
Te whakamahana:520–620°C (whakamātautau takirua kia pumau ai te āhua)
Whakarāpopototanga:
Ka taea e te H13 te tu atu i ngā pāmahana whakapakeke teitei ake, ka nui ake te pakeke o te mata. Heoi, he pai ake te ātete o te H12 ki ngā ru wera me te pumau o ngā āhuatanga i roto i ngā wāhanga taputapu nui.
6. Te Mahi i roto i te Hanga me te Maka Mate
AISI H12
-
He pai mōngā mate hanga, ngā taputapu kuti wera, mengā pokepokea aie pāngia ana e te huringa wera nui.
-
He tino pai tana mahi i roto i ngā āhuatanga e hiahia ana kia pāngia tonutia me te ru wera nui.
-
He pai ake inapakari me te ātete ki te pakaruhe mea nui ake i te pakeketanga mōrahi.
AISI H13
-
E whakamahia whānuitia ana i roto ite whakarewatanga mate pēhanga, ngā pokepokea werohanga kirihou, mengā pūnaha kaikawe wera.
-
He kōwhiringa pai mō ngā taputapu e hiahiatia anawhakaotinga mata paime te ātete nui ki te kakahu.
-
He pai ake te mahi i raro i te whakamahinga roa ki ngā koranu konumohe rewa, ki te konupora rānei.
Hei whakarāpopototanga:
-
KōwhiriH12mōtaumaha, ngāwari ki te pāngā mahi whakahaere.
-
KōwhiriH13mōte makanga mate tikae hiahia ana kia nui ake te mārō o te mata.
7. Ātete ki te ngenge wera
Ko te ngenge wera, te "tirotiro wera" rānei, he momo rahunga noa i roto i ngā taputapu mahi wera.
E ātete pai ana a AISI H12 me H13 i tēnei, engari he rerekē ngā tikanga matua.
-
H12:Ka whakamahi i te tungsten hei ātete i te whakangawari o te hanganga, hei pupuri hoki i te pumau i raro i te huringa wera.
-
H13:E whakawhirinaki ana ki ngā warowaiha vanadium mō te pumau o te mata me te ātete ki te ngatata.
Mōngā taputapu e pāngia ana e ngā huringa pāmahana tino nui, he pai ake te mahi a te AISI H12 nā tōna pakari me te iti ake o te aro ki ngā huringa pāmahana tere.
8. Ātete ki te Mau me te Hototahi ki te Maimoatanga Mata
-
AISI H13ka hanga i ngā warowaiha vanadium pai rawa, ka nui ake te ātete ki te kakahu i te wa e rere ana te konganuku pēhanga teitei, pērā i ngā pokepoke whakarewa me ngā pokepoke extrusion.
-
AISI H12ahakoa he ngawari ake, he roa ake te ora mō ngā mahi hanga taumaha.
Ka taea ngā maitai e rua tepania ki te nitride, ki te PVD rāneihei whakaroa i te roa o te ratonga.
Ka whakanui ake te nitriding i te pakeke o te mata ki runga ake i te1000 HV, e whakarato ana i te tiakitanga pai rawa atu mai i te horo me te kakahu piri.
9. Te Āheinga ki te Mīhini me te Whakarewa
| Āhuatanga | AISI H12 | AISI H13 |
|---|---|---|
| Te āheinga ki te mīhini | He māmā ake te mīhini | He uaua ake te mahi mīhini |
| Āheitanga whakarewa | He tino pai me te whakamahana i mua | He pai me te wera whakahaere |
| Te pāmahana whakamahana | 250–350°C | 250–400°C |
| Maimoatanga Wera i Muri i te Whakarewatanga | Whakamātauria tonutia | Whakamātauria tonutia |
Mā te hanganga o te AISI H12 ka maeneene ake te mahi miihini me te whakatikatika whakarewa, ā, he pai ake tēnei ina nui te auau o te tukatuka muri me te whakatikatika pokepokea ai.
10. Ngā Whakaaro mō te Utu
Ahakoa he rite te utu o ngā tohu e rua, ko te AISI H12 te mea nui rawa atuhe iti ake te ohanganā te iti o te ihirangi vanadium me te māmā ake o te hoahoa koranu.
Heoi, i ngā tono e nui ake ai te hiranga o te roa o te whakamahi o te taputapu me te kounga o te mata i te utu tīmatanga, ka pai ake pea te uara mō te wā roa e tukuna ana e te AISI H13.
Ngā kamupene pēnei iSAKYSTEELwhakarato i ngā taumata e rua i roto i ngā momo tuku utu-whai hua—kia whakarite kia tutuki i ngā kiritaki te ōwehenga mahi-ki-te-utu pai rawa atu i runga i ā rātou hiahia whakaputa.
11. Ngā Taunakitanga mō te Tono
| Tono | Rino i Manakohia | Take |
|---|---|---|
| Ngā mate hanga maturuturu | AISI H12 | Te pakari teitei, te ātete pānga |
| Ngā pokepokea ai te konumohe | AISI H13 | He ātete kakahu pai rawa atu, he whakaotinga mata |
| Ngā taputapu kuti wera | AISI H12 | Ātete ru |
| Ngā pokepokea werohanga kirihou | AISI H13 | Te pumau o te āhua |
