4140 Steel Wear Resistance: Ndi Yolimba Motani?

M'mafakitale omwe zida zachitsulo zimapirira mikangano, kugunda, ndi ma abrasion tsiku lililonse,kuvala kukanaimakhala chinthu chofunikira kwambiri. Kaya ndi magiya omwe amazungulira pansi pa katundu wolemetsa kapena ma shaft omwe amayenda mobwerezabwereza, zigawozo ziyenera kupangidwa kuchokera ku zipangizo zolimba kuti zikhalepo. Chimodzi mwazitsulo zodalirika kwambiri m'derali ndi4140 aloyi zitsulo.

Imadziwika chifukwa cha mphamvu zake zamakina komanso kulimba mtima, 4140 imadzitamandiranso kukana kuvala kochititsa chidwi, ikakonzedwa moyenera.sakysteelimayang'ana momwe chitsulo cha 4140 chilili cholimba kwambiri pankhani yokana kuvala, komanso chifukwa chake ndi chinthu choyenera kupsinjika kwambiri, kugwiritsa ntchito zovala zapamwamba.

Kodi 4140 Steel ndi chiyani?

4140 ndichromium-molybdenum low-alloy chitsulozomwe zimapereka kuphatikiza kwapadera kwamphamvu, kulimba, kuuma, ndi kukana kuvala. Ndi ya AISI-SAE chitsulo grading system ndipo imagwiritsidwa ntchito kwambiri popanga zida zolondola, makina olemetsa, ndi zida.

Kapangidwe kakemidwe kake:

• Mpweya: 0.38 - 0.43%

• Chromium: 0.80 - 1.10%

• Manganese: 0.75 - 1.00%

• Molybdenum: 0.15 - 0.25%

• silicon: 0.15 - 0.35%

Chromium imathandizira kulimba komanso kukana kuvala, pomwe molybdenum imathandizira kulimba komanso kutentha kwambiri. Izi alloying zinthu kupanga4140 zitsulozoyenerera mbali zomwe zimayenera kukana kuwonongeka kwapamtunda kwa nthawi yayitali.

Kodi Wear Resistance N'chiyani?

Valani kukanandi kuthekera kwa chinthu kupirira kuwonongeka kwa pamwamba komwe kumachitika chifukwa cha makina. Izi zitha kuphatikiza:

• Abrasion(kupukuta, kupukuta)

• Kumamatira(frictional transfer of material)

• Kukokoloka(kukhudzidwa kwa particles kapena madzimadzi)

• Zosangalatsa(ma micro-movement pansi pa katundu)

Kukana kuvala kwakukulu kumatanthauza kuti chigawocho chidzakhala nthawi yayitali muutumiki, kuchepetsa ndalama zokonzekera ndi nthawi yopuma.

Kodi 4140 Steel Imagwira Ntchito Motani mu Wear Resistance?

Chitsulo cha 4140 sichitsulo cholimba kwambiri pamsika, koma kukana kwake kumakhalakwambiri customizable. Kudzera moyenerakutentha mankhwala, chitsulo ichi chikhoza kusinthidwa kuchoka ku machinable, mphamvu zochepetsetsa kukhala zolimba, zosavala mphamvu.

1. Mu Annealed Condition

• Yofewa komanso yosavuta kusinthika

• Kulimba kochepa (~ 197 HB)

• Kukana kuvala kumakhala kochepa

• Oyenera kukonzanso kwina monga Machining kapena kuwotcherera

2. Pambuyo pa Kutentha ndi Kutentha

• Kuwonjezeka kwakukulu kwa kuuma kwapansi (mpaka 50 HRC)

• Mphamvu yolimba imaposa 1000 MPa

• Kukana kwabwino kwa kuvala kwa ntchito zolemetsa mpaka zolemetsa

• Kulimba koyenera kumalepheretsa kusweka pogwedezeka kapena kupsinjika mobwerezabwereza

At sakysteel, nthawi zambiri timapereka zitsulo 4140 muwozimitsidwa ndi wofatsakukulitsa mphamvu zonse ndi kuvala magwiridwe antchito. Izi zimapangitsa kuti zikhale zoyenera pazinthu zosunthika monga ma shafts, ma axles, ndi ma gear opanda kanthu.

Njira Zomwe Zimayambitsa 4140's Wear Resistance

Pali zinthu zingapo zomwe zimathandizira kuti zitsulo za 4140 alloy zisavale:

• Zomwe zili mu Chromium
  Imakulitsa kuuma ndikukana kuvala kwa abrasive.

• Zowonjezera za Molybdenum
  Limbikitsani mphamvu ndi kuchepetsa chiopsezo cha kutentha-kufewa pa kutentha kwakukulu.

• Fine Microstructure
  4140 yotenthetsera imapanga mawonekedwe ofananirako a martensite omwe amakana kupunduka ndi kukwapula.

• Pamwamba Kuuma Kuwongolera
  Chitsulocho chikhoza kuumitsidwa pachimake kapena chokhazikika pamwamba, kupereka kusinthasintha kwa ntchito zinazake.

Kuyerekeza 4140 Valani Kutsutsana ndi Zida Zina

4140 vs 1045 Carbon Steel
4140 ili ndi kukana kwabwinoko kovala chifukwa cha kuuma kwakukulu komanso zomwe zili ndi aloyi. 1045 ndiyoyeneranso kugwiritsa ntchito kupsinjika kochepa.

4140 vs Zida Zitsulo (mwachitsanzo, D2, O1)
Zitsulo za zida ngati D2 zimapereka kukana kwamphamvu kwambiri pakanthawi koopsa, koma zimakhala zolimba komanso zovuta kumakina. 4140 imakhudza bwino magawo osunthika omwe amafunikira mphamvu komanso kulimba.

4140 vs Zitsulo zosapanga dzimbiri (mwachitsanzo, 316)
Zitsulo zosapanga dzimbiri zimalimbana ndi dzimbiri koma zimavala mwachangu ponyamula katundu. 4140 imakonda malo owuma, opangidwa ndi makina pomwe mikangano imawononga kwambiri kuposa dzimbiri.

Ntchito Zapadziko Lonse Zomwe Zimadalira 4140's Wear Resistance

Chifukwa cha kuuma kwake kosinthika komanso kulimba kwake, 4140 imagwiritsidwa ntchito pazinthu zingapo zomwe zimatha kuvala:

Makampani Agalimoto

• Kutumiza shafts

• Ma Camshafts

• Zowongola dzanja

• Zolemba za giya ndi spacers

Gawo la Mafuta & Gasi

• Zida zapansi

• Miyendo ya rotary

• Zigawo zapampopi zamatope

• Zolumikizana ndi zida zolumikizirana

Zida Zamakampani

• Ma hydraulic silinda

• Bushings ndi bearings

• Dinani ma platens

• Ma conveyor odzigudubuza

Zida ndi Imfa

• Zikhonya

• Zonyamula zida

• Ma block block

Mapulogalamuwa amakumana ndi kupsinjika mobwerezabwereza, kukangana, ndi kukhudzidwa - kupangitsa kukana kuvala kukhala kofunikira kuti pakhale ntchito yotetezeka, yothandiza komanso yokhalitsa.

Kodi 4140 Itha Kuthandizidwa Pamwamba Kuti Musagwirizane Ndi Kuvala Kwabwinoko?

Inde. 4140 zitsulo ndizogwirizana kwambiriumisiri pamwambanjira zomwe zimawonjezera kukana kuvulazidwa:

• Nitriding
  Amapanga malo olimba (mpaka 65 HRC) osasokoneza gawolo. Zabwino kwa zida.

• Induction Harding
  Imaumitsa pamwamba ndikusunga pachimake cholimba - chofala m'mitsinje ndi magiya.

• Carburizing
  Imawonjezera kaboni pamwamba kuti ikhale yolimba. Oyenera magawo omwe amakumana ndi kukangana ndi kukakamizidwa.

At sakysteel, timapereka chithandizo chaukadaulo kwa makasitomala omwe akufuna zida za 4140 za nitrided kapena induction-hardened.

Ubwino waukulu wa 4140 pa Wear Application

• Kuuma Kwambiri Pamwamba (mpaka 50 HRC kapena kupitilira apo)

• Kulimbitsa Kwambiri Kwambirikukana kusweka

• Chokhazikika Pakutenthandi cyclic loading

• Zokwera mtengopoyerekeza ndi zida zachitsulo

• Easy to Machine ndi Weldmusanalandire chithandizo chomaliza

• Imathandizira Kuwumitsa Kwambiri Pamwamba

Ubwinowu umapangitsa 4140 kukhala chisankho chosankha mainjiniya omwe amapanga zida zosuntha zomwe ziyenera kukhalitsa.

Chitsimikizo cha Ubwino kuchokera ku sakysteel

Pamene kuvala kumafunika,kulamulira khalidwe ndi chirichonse. Pasakysteel, tikuwonetsetsa kuti magwiridwe antchito amagwirizana ndi:

• Wotsimikizikakusanthula kwamankhwala ndi makina

• Kuwunika kwambiri kutentha kwamankhwala

• Kuyesa kuuma kolondola

• Chitsimikizo cha EN10204 3.1

• Kukambilana pamwamba pa chithandizo chamankhwala

Timapereka zitsulo 4140 mumitundu yotentha yokulungidwa, yokokedwa, yonyezimira, ndi makina olondola, ogwirizana ndi zomwe mukufuna kugwiritsa ntchito.

Mapeto

Ndiye chitsulo cha 4140 ndi cholimba bwanji -kwenikweni? Yankho lake ndi lodziwikiratu:zolimba kwambiri, makamaka pamene kutentha kuchitidwa moyenera. Ndi mphamvu yake yabwino kwambiri ya kuuma kwa pamwamba, mphamvu yapakati, ndi machinability, chitsulo cha 4140 alloy chimapereka kukana kuvala kodalirika mu chirichonse kuchokera ku ma axle amagalimoto kupita ku zida zobowola zolemetsa.

Ngati ntchito yanu ikukhudzana ndi kukangana, kukhudzidwa, kapena kuyabwa,4140 zitsulo kuchokera ku sakysteelndi yankho lodalirika lomwe limapangidwira moyo wautali komanso magwiridwe antchito.
