AISI 4140 (42CrMo)ndiye chitsulo chosunthika komanso chogwiritsidwa ntchito kwambiri padziko lonse lapansi cha "Chrome-Moly" alloy steel. Ndiwodziwika bwino chifukwa cha bwino kwambirimphamvu, kulimba, ndi kuvala kukana.
Mosiyana muyezo mpweya zitsulo, Kuwonjezera waChromium (Cr)ndiMolybdenum (Mo)imalola 4140 kukhala yotentha-kutenthedwa kuti ikhale yolimba komanso yolimba kwambiri. Timapereka izi makamaka muKuzimitsidwa ndi Kupsya mtima (Q+T)chikhalidwe (kawirikawiri 28-32 HRC), amene amalola makasitomala makina makina mwachindunji popanda mankhwala kutentha, kupewa kupotoza zoopsa. Ndizinthu zomwe mungasankhemagawo otumizira mphamvumu autommafakitale, mafuta & gasi, ndi migodi.
Mafotokozedwe a Zamalonda & Zofanana ndi Magiredi
Timapereka-zitsulo zamphamvu za 4140/42CrMo zomwe zimakwaniritsa miyezo yapadziko lonse lapansi, kuwonetsetsa kuti mapulojekiti apadziko lonse agwirizana.

Zofunika Kwambiri ndiUbwino wake
- Kuwumitsa Kwambiri:Chromium-Molybdenum alloy imalola chitsulo kuuma mozama, kuonetsetsa kuti chitsulocho chikhale cholimba ngakhale m'magawo akulu akulu-(monga ma shafts 500mm).
- Kutopa Kwabwino Kwambiri:Ndiabwino pazigawo zokhala ndi katundu wozungulira komanso kugwedezeka, monga ma axle amagalimoto ndi makolala obowola.
- Kupezeka - kolimba (QT):Timagulitsa 4140 muPre-zowumitsidwa (28-32 HRC)chikhalidwe. Izi zimachotsa mtengo ndi nthawi ya positi{1}}mankhwala otenthetsera makina ndikuonetsetsa kuti gawo lomaliza silingasinthe.
- Kuchita bwino:Ikaumitsidwa kapena{0}panthawi yowumitsidwa, imagwira bwino ntchito yomaliza bwino.
- Kuvuta Kwambiri:Chapamwamba kuposa muyezo wa carbon steel (monga 1045), kukana kusweka pansi pa katundu wodabwitsa.
Mapulogalamu Okhazikika
4140/42CrMo ndiye "Wogwira Ntchito" wa dziko la uinjiniya:
Mafuta & Gasi
Bowola makolala, ma kelly bar, ndi zomangira -zam'nyanja (zimafunika mayendedwe okhwima a API).
Zagalimoto
Ma axle shafts, crankshafts, ndodo zolumikizira, ndi zowongolera.
Makina
Magiya akuluakulu, masipingo, ma conveyor rolls, ndi -maboliti apamwamba kwambiri (Giredi 10.9).
Migodi
Zikhomo zofukula, mikwingwirima ya rock, ndi ndodo za hydraulic cylinder.
Maziko a Mold
Nthawi zambiri amagwiritsidwa ntchito ngati chotchinga chachikulu-chimake cholimba cha nkhungu zapulasitiki.
FAQ
Q1: Kodi pali kusiyana kotani pakati pa 4140 ndi 42CrMo?
A1: Ndi ofanana pafupifupi. 4140 ndi dzina la ku America (AISI), pamene 42CrMo ndi dzina la Chitchaina (GB). Mapangidwe awo amankhwala ndi makina amakina amatha kusinthana mu 99% ya zojambula zauinjiniya.
Q2: Kodi "4140 QT" amatanthauza chiyani?
A2: QT imayimira Quenched and Tempered. Zikutanthauza kuti chitsulocho chakhala kale kutentha-kutenthedwa mpaka kuuma kwanthawi zambiri 28-32 HRC (280-320 HB). Mutha kuziyika molunjika mugawo lomalizidwa popanda chithandizo china cha kutentha. Ichi ndiye chikhalidwe chathu chodziwika bwino choperekera.
Q3: Kodi zitsulo 4140 zitha kuwotcherera?
A3: Inde, koma mosamala. Chifukwa cha kuuma kwake, 4140 imakonda kusweka ngati yotenthetsera kuzizira. Iyenera kutenthedwa kale (kufikira pafupifupi . 200-300 digirii ) isanawotchere ndi kuzizidwa pang'onopang'ono pambuyo pake. Gwiritsani ntchito{{6}ma elekitirodi a haidrojeni ochepa.
Q4: Kodi 4140 ndi yamphamvu kuposa chitsulo cha 1045?
A4: Inde, kwambiri. 4140 ili ndi mphamvu zochulukira kwambiri, zokolola, komanso kutopa kuposa 1045 carbon steel{3}} yomwe imagwiritsidwa ntchito pamene 1045 ilibe mphamvu zokwanira kulepheretsa kupindika kapena kusweka.
