Te Mārama ki te Rino D2

Tirohanga Whānui

maitai D2He maitai taputapu waro-teitei, konupora-teitei te mea e mōhiotia ana mō tōna ātete ki te kakahu me tōna pakeketanga. E whakarōpūtia ana hei maitai haurua-kowiri tira nā te mea kei te rohe o te whakarōpūtanga kowiri tira katoa tōna ihirangi konupora (tata ki te 12%). He mea whakamahi noa i roto i ngā taputapu tapahi ahumahi me ngā maripi kounga teitei, he mea nui te D2 mō te pupuri i ngā taha me te roa.

Ngā Āhuatanga Matua

• Te pakeketanga: 58–62 HRC i muri i te maimoatanga wera

• Ātete KakahuHe tino pai nā te nui o te ihirangi carbide

• Te pakariWaenga

• Ātete ki te WaikuraPai ake i te nuinga o ngā maitai waro engari iti iho i ngā maitai kore waikura

• Te Pupuri i te TapaTino teitei

Ngā Whakamahinga Noa

• Ngā mate me ngā patu ahumahi

• Ngā maripi pūmau me ngā maripi whakapiko kounga teitei

• Ngā mata kutikuti

• Ngā taputapu tapahi me te hanga

Te Mārama ki te Rino 8Cr13MoV

Tirohanga Whānui

He maitai kore waikura Hainamana te 8Cr13MoV, he mea whakarite ki te maitai AUS-8 Hapanihi. He taurite te pakeke, te ātete ki te waikura, me te utu whaitake. He whānuitia te whakamahinga i roto i ngā maripi utu waenga me te utu iti nā te mea he pai te mahi me te ngāwari ki te whakakoi.

Te Hanganga Matū

Te hanganga noa o te maitai 8Cr13MoV:

• Waro (C): 0.75 – 0.85%

• Konukōmiuma (Kr): 13.0 – 14.5%

• Molibdenuma (Mo): 0.10 – 0.30%

• Vanadium (V): 0.10 – 0.25%

• Manganēhi (Mn): ≤ 1.0%

• Hiraka (Si): ≤ 1.0%

Ngā Āhuatanga Matua

• Te pakeketanga: 57–59 HRC i muri i te maimoatanga wera

• Ātete KakahuWaenga

• Te pakariHe pai mō te maitai kore waikura

• Ātete ki te WaikuraTeitei nā te nui ake o te ihirangi chromium

• Te Pupuri i te TapaHe āhua noa, he māmā ake te whakakoi i ngā maitai mārō ake

Ngā Whakamahinga Noa

• Ngā maripi kawe i ia rā (EDC)

• Ngā maripi kīhini

• Ngā maripi o waho me ngā maripi whai hua

• Ngā maripi takai utu iti

Te maitai D2 me te maitai 8Cr13MoV: Whakataurite Taipitopito

1. Te Pakari me te Pupuri Tapa

• D2 RinoKo te pakeketanga teitei ake (tae atu ki te 62 HRC) ko te tikanga he roa ake te pupuri i te mata, ā, he iti ake te whakakoi i ngā wā katoa. Heoi, he uaua ake te whakakoi ina mangu.

• Rino 8Cr13MoVHe iti ake te mārō engari he māmā ake te whakakoi, he mea ngāwari ake mā te hunga whakamahi noa.

2. Ātete ki te Mau

• D2 RinoHe ātete pai ki te kakahu nā te nui o te waro me te carbide, he mea tino pai mō ngā mahi tapahi taumaha.

• Rino 8Cr13MoVHe ātete pai ki te kakahu engari kāore i te rite ki te D2, he pai mō te whakamahinga taurite.

3. Ātete ki te Waikura

• D2 RinoKowiri tira; he pai ake te ātete ki te waikura i te maitai waro noa engari ka ngāwari tonu te poke i ngā taiao makuku, tote rānei, ki te kore e tiakina tika.

• Rino 8Cr13MoVHe kowiri tira katoa, he nui ake te chromium, ā, he pai ake te ātete ki te waikura i ngā āhuatanga mākū.

4. Te pakari

• D2 RinoHe pakari āhua; ka pakarukaru mēnā ka whakamahia mō te werowero, mō te pā kino rānei.

• Rino 8Cr13MoVHe pakari ake, he ngāwari ake i te whakamahinga taratara.

5. Ngāwari o te Whakakoi

• D2 RinoHe uaua ake te whakakoi nā te pakeke me te ātete ki te pakaru; me whakamahi taputapu whakakoi taimana, uku rānei.

• Rino 8Cr13MoVHe tino māmā ake te whakakoi me ngā taputapu whakakoi paerewa, ahakoa i te parae.

6. Te utu

• D2 RinoHe nui ake te utu i te nuinga o te wā, e whakamahia ana i roto i ngā maripi kounga teitei me ngā maripi ngaio.

• Rino 8Cr13MoVHe iti te utu, e rongonui ai mō ngā maripi utu iti me te mahi pai.
