Steel Bar 4140 vs 4130 vs 4340: Zonse Zomwe Muyenera Kudziwa?

Zikafika posankha zitsulo zoyenerera zamakina, zamlengalenga, kapena zamakampani, mayina atatu nthawi zambiri amabwera patsogolo -4140, 4130,ndi4340. Zitsulo zotsika aloyi za chromium-molybdenum zimadziŵika chifukwa cha mphamvu zake, kulimba mtima, ndi machina. Koma mumadziwa bwanji kuti ndi iti yomwe ili yoyenera pulojekiti yanu?

Mu bukhuli lathunthu, tikufanizira4140 vs 4130 vs 4340 mipiringidzo yachitsulokudutsa ma metrics ofunikira monga kapangidwe kakemidwe, mawonekedwe amakanika, kuuma, kutenthetsa, kutentha kutentha, ndi kukwanira kwa ntchito - akatswiri opanga, opanga zinthu, ndi ogula kupanga zisankho zanzeru.

1. Chiyambi cha 4140, 4130, ndi 4340 Steel Bars

1.1 Kodi Zitsulo Zochepa-Alloy Ndi Chiyani?

Zitsulo zotsika ndi zitsulo za kaboni zomwe zimaphatikizapo zinthu zazing'ono za alloying monga chromium (Cr), molybdenum (Mo), ndi faifi tambala (Ni) kuti apititse patsogolo zinthu zina.

1.2 Chidule cha Giredi Iliyonse

• 4140 Chitsulo: Chitsulo chosunthika chopatsa mphamvu komanso kulimba mtima, chomwe chimagwiritsidwa ntchito kwambiri popanga zida, zida zamagalimoto, ndi uinjiniya wamba.

• 4130 Zitsulo: Wodziwika chifukwa cha kulimba kwake kwakukulu komanso kuwotcherera, komwe nthawi zambiri amagwiritsidwa ntchito pazandege ndi ma motorsports.

• 4340 Chitsulo: Nickel-chromium-molybdenum alloy yokhala ndi mphamvu zochulukirapo komanso kukana kutopa, yomwe imayamikiridwa pazamlengalenga ndi ntchito zolemetsa.

2. Kuyerekeza kwa Chemical Composition

Mfundo zazikuluzikulu:

• 4340wawonjezeranickel, kukupatsani kulimba kwambiri komanso kukana kutopa.

• 4130ali ndi mpweya wochepa wa carbon, kusinthaweldability.

• 4140ali ndi kaboni wambiri ndi manganese, amawonjezerakuuma ndi mphamvu.

3. Kuyerekeza Katundu Wamakina

4. Chithandizo cha Kutentha ndi Kuuma

4130

• NormalizingKutentha: 870-900°C

• Kuwumitsa: Kuzimitsa mafuta kuchokera ku 870 ° C

• KutenthaKutentha: 480-650°C

• Zabwino kwambiri za: Mapulogalamu akufunikaweldabilityndikulimba

4140

• Kuwumitsa: Kuzimitsa mafuta kuchokera ku 840–875°C

• KutenthaKutentha: 540-680°C

• Kuuma mtima: Zabwino kwambiri - zozama zowumitsa zomwe zingatheke

• Zabwino kwambiri za: Mitsinje yamphamvu kwambiri, magiya, ma crankshafts

4340

• Kuwumitsa: Mafuta kapena polima kuzimitsa kuchokera 830-870 ° C

• KutenthaKutentha: 400-600°C

• Zodziwika: Imasungabe mphamvu ngakhale mutaumitsa kwambiri

• Zabwino kwambiri za: Zida zoikira ndege, zida zoyendetsera ntchito zolemetsa

5. Weldability ndi Machinability

4130imadziwika kuti imatha kuwotcherera mosavuta pogwiritsa ntchito TIG/MIG popanda kusweka kwambiri, yabwino pamachubu monga mazenera opukutira kapena mafelemu andege.

6. Ntchito ndi Makampani

6.1 4130 Ntchito Zachitsulo

• Aerospace tubing

• Mafelemu othamanga ndi makola odzigudubuza

• Mafelemu a njinga zamoto

• Olandira mfuti

6.2 4140 Ntchito Zachitsulo

• Zonyamula zida

• Ma Crankshafts

• Magiya

• Ma axles ndi shafts

6.3 4340 Ntchito Zachitsulo

• Zida zoyatsira ndege

• Maboti amphamvu kwambiri ndi zomangira

• Zolemera makina zigawo zikuluzikulu

• Miyendo yamakampani amafuta ndi gasi

7. Kuganizira za Mtengo

Chifukwa chakezinthu za nickel, 4340 ndiyokwera mtengo kwambiri. Komabe, ntchito yake m'mapulogalamu ofunikira nthawi zambiri imatsimikizira mtengo wake.

8. Miyezo Yadziko Lonse ndi Maudindo

Onetsetsani kuti ogulitsa zitsulo zanu amapereka ziphaso zoyezetsa mphero zomwe zimagwirizana ndi zofunikira mongaASTM A29, EN 10250, kapenaChithunzi cha JIS G4053.

9. Momwe Mungasankhire Malo Oyenera Chitsulo

10. Mapeto

Mumpikisano waChitsulo Bar 4140 vs 4130 vs 4340, palibe wopambana m'modzi - kusankha koyenera kumatengera zanuntchito, mphamvu, mtengo, ndi zofunikira kuwotcherera.

• Sankhani4130ngati mukufuna weldability kwambiri ndi mphamvu zolimbitsa.

• Pitani ndi4140kwa njira yamphamvu kwambiri, yotsika mtengo yoyenera shafts ndi magiya.

• Sankhani4340pamene kuuma kwakukulu, mphamvu ya kutopa, ndi kukana kugwedezeka ndizofunikira.
