Kodi zitsulo 4140 ndi zamtundu wanji?

Chitsulo cha 4140 ndi chitsulo chodziwika bwino chomwe chimadziwika chifukwa champhamvu, kulimba, komanso kusinthasintha. Ndi m'banja lazitsulo za chromium-molybdenum, zomwe zimapereka kuphatikiza kwapadera kwazinthu zamakina zomwe zimapangitsa kukhala chisankho chokonda kwambiri ntchito zamafakitale. Mainjiniya, opanga zinthu, ndi opanga amagwiritsa ntchito kwambiri chitsulochi pachilichonse kuyambira mbali zamagalimoto mpaka zamakina.

Munkhaniyi ya SEO, sakysteel ikupereka chidule cha4140 zitsulo, kuphatikizapo kapangidwe kake ka mankhwala, makina ake, njira zothandizira kutentha, ndi ntchito wamba.

Gawo la 4140 Steel

4140 ndi chitsulo chochepa cha alloy chomwe chimagwera pansi pa dongosolo la SAE-AISI. Amadziwikanso kutiAISI 4140, EN19 (ku Europe),ndiSCM440 (ku Japan). Mawu akuti "4140" amatanthauza zomwe zili ndi aloyi:

  • "41" imasonyeza chitsulo cha chromium-molybdenum

  • "40" ikuyimira pafupifupi mpweya wa carbon (0.40%)

Chitsulo cha 4140 sichitsulo chosapanga dzimbiri, chifukwa sichikhala ndi chromium yokwanira kupereka kukana dzimbiri. M'malo mwake, imakhala yamtengo wapatali chifukwa cha mphamvu zake zamakina ndi kuuma pambuyo pa chithandizo cha kutentha.

Mapangidwe a Chemical a 4140 Steel

Kapangidwe kake ka 4140 ndi komwe kamapatsa mphamvu zake zamakina. Mipata yodziwika bwino ndi:

  • Mpweya (C):0.38% - 0.43%

  • Chromium (Cr):0.80% - 1.10%

  • Manganese (Mn):0.75% - 1.00%

  • Molybdenum (Mo):0.15% - 0.25%

  • Silicon (Si):0.15% - 0.35%

  • Phosphorous (P):≤ 0.035%

  • Sulfure (S):≤ 0.040%

Zinthu izi zimagwirira ntchito limodzi kuti zithandizire kulimba, kukana kuvala, komanso kulimba kwathunthu, ndikupanga 4140 kukhala zinthu zomwe zimafunikira zida zamakina.

Mechanical Properties of 4140 Steel

4140 imapereka mitundu yochititsa chidwi yamakina, makamaka pambuyo pa chithandizo choyenera cha kutentha. Izi zikuphatikizapo:

  • Kulimba kwamakokedwe:Mpaka 1100 MPa (160 ksi)

  • Mphamvu Zokolola:Pafupifupi 850 MPa (123 ksi)

  • Elongation pa Break:Pafupifupi 20%

  • Kulimba:Kawirikawiri 197 mpaka 235 HB mu chikhalidwe chokhazikika, mpaka 50 HRC pambuyo pozimitsa ndi kutentha

Makhalidwewa amatha kusiyanasiyana malinga ndi mawonekedwe achitsulo (bar, mbale, forged) ndi chikhalidwe cha kutentha.

Chithandizo cha Kutentha kwa 4140 Steel

Chithandizo cha kutentha ndi njira yofunika kwambiri yomwe imathandizira ntchito ya4140 zitsulo. Chitsulo chikhoza kuchitika m'njira zotsatirazi:

  1. Annealing
    Kuziziritsa pang'onopang'ono kuchokera pafupifupi 850 ° C kuti muthe kuwongolera ndikuchepetsa kupsinjika kwamkati. Izi zimabweretsa kapangidwe kofewa ndi ductility bwino.

  2. Normalizing
    Kutenthetsa mpaka 870 ° C kuti muyeretsenso mbewu. Amapereka malire a mphamvu ndi kulimba.

  3. Kutentha ndi kuzizira
    Imaumitsidwa ndi kutentha mpaka pafupifupi 845 ° C ndikuzizira mwachangu m'mafuta kapena m'madzi, kutsatiridwa ndi kutentha mpaka kuuma komwe kumafunidwa. Izi zimawonjezera kwambiri mphamvu ndi kuvala kukana.

  4. Kuchepetsa Kupsinjika
    Amachitidwa mozungulira 650 ° C kuti muchepetse kupsinjika kotsalira kuchokera ku makina kapena kuwotcherera.

Pa sakysteel, timapereka4140 zitsulom'malo osiyanasiyana otetezedwa ndi kutentha kutengera zomwe makasitomala amafuna, kuwonetsetsa kuti ntchito yanu ikugwira ntchito kwambiri.

Ubwino wa 4140 Steel

  • Kuchuluka kwa Mphamvu ndi Kulemera Kwambiri:Ndibwino kuti muchepetse kulemera.

  • Kukana Kutopa Kwabwino:Imalimbana ndi kutsitsa kwa cyclic, koyenera magiya ndi ma shafts.

  • Kuuma Kwabwino Kwambiri:Amapeza kuuma kwambiri pambuyo kuzimitsa.

  • Kuthekera:Mosavuta machinable mu annealed kapena normalized zinthu.

  • Weldability:Ikhoza kuwotcherera ndi preheating yoyenera ndi post-weld chithandizo.

Zopindulitsa izi zimapangitsa chitsulo cha 4140 kukhala chosankha chachuma pamapulogalamu ambiri opsinjika kwambiri.
