Chitsulo chachitsulo 4140 vs 4130 vs 4340: Zonse Zomwe Mukuyenera Kudziwa?

Ponena za kusankha bala yoyenera yachitsulo chopangidwa ndi makina, ndege, kapena mafakitale, mayina atatu nthawi zambiri amabwera patsogolo —4140, 4130ndi4340Zitsulo za chromium-molybdenum izi zomwe zimakhala ndi aloyi ochepa zimadziwika chifukwa cha mphamvu zawo, kulimba kwawo, komanso luso lawo lotha kupanga makina. Koma mungadziwe bwanji chomwe chili choyenera ntchito yanu?

Mu bukuli lofotokoza bwino, tikuyerekezaMipiringidzo yachitsulo ya 4140 vs 4130 vs 4340paziyeso zofunika monga kapangidwe ka mankhwala, mawonekedwe a makina, kuuma, kusinthasintha, kutentha, ndi kuyenerera kugwiritsa ntchito — kuthandiza mainjiniya, opanga zinthu, ndi ogula kupanga zisankho zodziwikiratu.

1. Chiyambi cha Mipiringidzo ya Chitsulo ya 4140, 4130, ndi 4340

1.1 Kodi Zitsulo Zopanda Aloyi Ndi Chiyani?

Zitsulo zotsika kwambiri ndi zitsulo za kaboni zomwe zimaphatikizapo zinthu zochepa monga chromium (Cr), molybdenum (Mo), ndi nickel (Ni) kuti ziwongolere mawonekedwe enaake.

1.2 Chidule cha Giredi Iliyonse

• 4140 ChitsuloChitsulo chogwiritsidwa ntchito mosiyanasiyana chomwe chimapereka mphamvu ndi kuuma kwabwino kwambiri, chomwe chimagwiritsidwa ntchito kwambiri popanga zida, zida zamagalimoto, komanso uinjiniya wamba.

• 4130 Chitsulo: Yodziwika chifukwa cha kulimba kwake kwakukulu komanso kuthekera kwake kusinthasintha, yomwe imagwiritsidwa ntchito nthawi zambiri mu ndege ndi masewera a njinga zamoto.

• 4340 Chitsulo: Chopangira cha nickel-chromium-molybdenum chokhala ndi mphamvu zambiri komanso cholimba, chomwe chimagwiritsidwa ntchito poyendetsa ndege komanso kugwiritsa ntchito zinthu zolemera.

2. Kuyerekeza kwa Mankhwala

Mfundo Zofunika:

• 4340wawonjezeranikeli, zomwe zimaipangitsa kukhala yolimba komanso yolimba.

• 4130ali ndi mpweya wochepa, zomwe zimapangitsa kutikusinthasintha.

• 4140ali ndi carbon ndi manganese wambiri, zomwe zimapangitsa kuti magazi azithamanga kwambiri.kuuma ndi mphamvu.

3. Kuyerekeza kwa Katundu wa Makina

4. Kutentha ndi Kulimba

4130

• Kusinthakutentha: 870–900°C

• Kuuma: Kuzimitsa mafuta kuchokera ku 870°C

• Kuchepetsa kutenthakutentha: 480–650°C

• Zabwino kwambiri pa: Mapulogalamu ofunikirakusinthasinthandikulimba

4140

• Kuuma: Chozimitsira mafuta kuchokera 840–875°C

• Kuchepetsa kutenthakutentha: 540–680°C

• Kulimba: Zabwino kwambiri — kulimbitsa chikwama chozama kwambiri kungatheke

• Zabwino kwambiri pa: Ma shaft amphamvu kwambiri, magiya, ma crankshaft

4340

• Kuuma: Mafuta kapena chozimitsira cha polima kuchokera ku 830–870°C

• Kuchepetsa kutenthakutentha: 400–600°C

• Zodziwika bwino: Imasunga mphamvu ngakhale itauma kwambiri

• Zabwino kwambiri pa: Zida zotera ndege, zida zoyendetsera zinthu zolemera

5. Kutha kupotoza ndi Kutha kuyika makina

4130Imadziwika bwino chifukwa chosavuta kuwotcherera pogwiritsa ntchito TIG/MIG popanda kusweka kwambiri, yabwino kwambiri pakupanga mapaipi monga ma roll cages kapena mafelemu a ndege.

6. Mafomu Ogwiritsidwa Ntchito ndi Makampani

6.1 4130 Kugwiritsa Ntchito Zitsulo

• Mapaipi amlengalenga

• Mafelemu a mpikisano ndi ma roll cages

• Mafelemu a njinga zamoto

• Zolandira mfuti

6.2 4140 Kugwiritsa Ntchito Zitsulo

• Zipangizo zogwirira ntchito

• Ma crankshaft

• Magiya

• Ma axles ndi ma shaft

6.3 4340 Kugwiritsa Ntchito Zitsulo

• Zida zotera ndege

• Maboti ndi zomangira zolimba kwambiri

• Zipangizo zamakina olemera

• Ma shaft a mafakitale a mafuta ndi gasi

7. Zoganizira za Mtengo

Chifukwa chakuchuluka kwa nikeli, 4340 ndiye yokwera mtengo kwambiriKomabe, magwiridwe ake pantchito yovuta nthawi zambiri amatsimikizira mtengo wake.

8. Miyezo ndi Maudindo Padziko Lonse

Onetsetsani kuti ogulitsa zitsulo anu akupereka satifiketi yoyesera mphero yomwe ikugwirizana ndi miyezo yoyenera mongaASTM A29, EN 10250kapenaJIS G4053.

9. Momwe Mungasankhire Chitsulo Choyenera

10. Mapeto

Mu mpikisano waChitsulo chachitsulo 4140 vs 4130 vs 4340Palibe wopambana aliyense — chisankho choyenera chimadalira zomwe mukufunamagwiridwe antchito, mphamvu, mtengo, ndi zofunikira pakuwotcherera.

• Sankhani4130Ngati mukufuna kusinthasintha bwino komanso mphamvu zochepa.

• Pitani ndi4140kuti mupeze njira yolimba kwambiri komanso yotsika mtengo yoyenera ma shaft ndi magiya.

• Sankhani4340pamene kulimba kwambiri, mphamvu ya kutopa, ndi kukana kugwedezeka ndizofunikira kwambiri.
