4140 Alloy Steel Tensile: Ndi Yamphamvu Motani Kwenikweni?

Mu engineering ndi kupanga, mphamvu ndiye chinthu chofunikira kwambiri. Kaya ndi crankshaft mu injini yamagalimoto kapena pini yodzaza kwambiri pazida zomangira, kulimba kwamphamvu kumatsimikizira kuchuluka kwa katundu yemwe angagwire asanaswe. Pakati pazitsulo zambiri za alloy zomwe zilipo,4140 aloyi zitsulowadziŵika chifukwa cha kulimba kwake kochititsa chidwi, kulimba mtima, ndi kuchita zinthu mwanzeru.

Koma ndi chitsulo cholimba cha 4140 alloy-kwenikweni? M'nkhaniyi,sakysteelimalowera mkati mwazinthu zolimba za 4140, ndikuwunika zomwe zimapangitsa kuti ikhale yodalirika pakugwiritsa ntchito mwadongosolo komanso pamakina.

Kodi 4140 Alloy Steel ndi chiyani?

4140 ndichitsulo chochepa cha chromium-molybdenumamadziwika chifukwa cha mphamvu zake zolimba kwambiri komanso kukana kutopa kwabwino. Amagwiritsidwa ntchito kwambiri popanga, kupanga, kupanga zida, ndi zida zolemetsa.

Makina ofunikira a 4140 akuphatikizapo:

  • Mpweya:0.38% - 0.43%

  • Chromium:0.80% - 1.10%

  • Molybdenum:0.15% - 0.25%

  • Manganese:0.75% - 1.00%

  • Silikoni:0.15% - 0.35%

Zinthu zophatikizikazi zimakulitsa kulimba ndi mphamvu, kupanga 4140 imodzi mwazitsulo zodalirika kwambiri zogwiritsidwa ntchito mwamapangidwe.

Kumvetsetsa Kulimba Kwamphamvu

Kulimba kwamakokedweamatanthauza kuchuluka kwa mphamvu (kukoka kapena kutambasula) kupsinjika komwe chinthu chingapirire chisanalephere. Nthawi zambiri amayezedwa mkatimegapascals (MPa) or mapaundi pa lalikulu inchi (psi). Kuchuluka kwamphamvu kumatanthawuza kuti zinthuzo zimatha kupirira mphamvu zazikulu zisanapunduke kapena kusweka.

Mphamvu Yamphamvu ya 4140 Alloy Steel

Kulimba kwamphamvu kwachitsulo cha 4140 kumadalira kwambiri kutentha kwake:

1. Annealed Condition

Munthawi yake yofewa kwambiri (yotsekedwa), zitsulo 4140 zimapereka:

  • Kulimba kwamakokedwe:655 - 850 MPa

  • Mphamvu Zokolola:415 - 620 MPa

  • Kulimba:~ 197 HB

2. Normalized Condition

Pambuyo pa normalization, kapangidwe kachitsulo kamakhala kofananira, kumapangitsanso makina:

  • Kulimba kwamakokedwe:850 - 1000 MPa

  • Mphamvu Zokolola:650 - 800 MPa

  • Kulimba:~ 220 HB

3. Kuzima ndi Kukwiya (Q&T)

Izi ndizomwe zimachitika kwambiri pamapulogalamu ochita bwino kwambiri:

  • Kulimba kwamakokedwe:1050 - 1250 MPa

  • Mphamvu Zokolola:850 - 1100 MPa

  • Kulimba:28-36 HRC

At sakysteel, timapereka4140 aloyi zitsulom'malo osiyanasiyana otenthetsera kutentha, okometsedwa kuti agwirizane ndi zofunikira zamphamvu zamafakitale osiyanasiyana.

Chifukwa chiyani 4140's Tensile Mphamvu Ndi Yokwera Chonchi?

Zinthu zazikuluzikulu zomwe zimapangitsa kuti 4140 ikhale yolimba kwambiri ndi izi:

  • Zomwe zili mu Chromium:Amawonjezera kuuma ndi kuvala kukana

  • Molybdenum:Imawonjezera mphamvu pakutentha kwambiri ndikuwonjezera kuuma

  • Kusinthasintha kwa Chithandizo cha Kutentha:Amakonza ma microstructure kuti agwirizane ndi mphamvu zomwe mukufuna komanso kulimba mtima

  • Mulingo Woyenera wa Kaboni:Amapereka kuphatikiza kwabwino kwa mphamvu ndi ductility

Makhalidwewa amalola kuti 4140 ikhale yopambana kuposa zitsulo zambiri za carbon komanso ngakhale zida zina zazitsulo zikafika pa mphamvu zowonongeka pansi pa katundu.

Kodi 4140 Imafananiza Bwanji ndi Zitsulo Zina?

4140 vs 1045 Carbon Steel

  • 1045 ndi sing'anga kaboni chitsulo ndi mphamvu kumakoka kuzungulira 570 - 800 MPa.

  • 4140 imapereka 30% mpaka 50% mphamvu zowonjezera, makamaka ikatenthedwa.

4140 vs 4340 Chitsulo

  • 4340 imaphatikizapo nickel, yomwe imathandizira kulimba komanso kukana kutopa.

  • Ngakhale 4340 ikhoza kupereka kulimba kwapamwamba pang'ono, 4140 ndiyopanda ndalama zambiri ndi magwiridwe antchito ofanana.

4140 vs Stainless Steel (mwachitsanzo, 304, 316)

  • Zitsulo zosapanga dzimbiri za Austenitic zimapereka kukana kwa dzimbiri koma kutsika kwamphamvu (nthawi zambiri ~ 500 - 750 MPa).

  • 4140 ndi yamphamvu kuwirikiza kawiri koma iyenera kutetezedwa ku dzimbiri m'malo ankhanza.

Mapulogalamu Omwe Amadalira 4140's Tensile Strength

Chifukwa cha kulimba kwake kwakukulu, 4140 imagwiritsidwa ntchito kwambiri m'magawo omwe amapirira katundu wolemetsa kapena mphamvu zamphamvu. Zomwe zimagwiritsidwa ntchito ndizo:

Zagalimoto

  • Kuyendetsa shafts

  • Ma Crankshafts

  • Zigawo zoyimitsidwa

  • Zosowa za zida

Mafuta & Gasi

  • Dulani makolala

  • Zida zolumikizana

  • Matupi a valve

  • Zojambula za Hydraulic

  • Kumenya nkhonya ndi kufa

  • Zonyamula zida

  • Kupanga zida

Kutha kupirira katundu wokhazikika komanso wa cyclic kumapangitsa4140gwero lazinthu zosawerengeka zofunika m'mafakitale apadziko lonse lapansi.

Zinthu Zomwe Zimakhudza Kulimba Kwamphamvu Pakuchita

Kulimba kwamphamvu kwamphamvu kwa 4140 kumatha kusiyanasiyana pakugwiritsa ntchito zenizeni padziko lapansi kutengera:

  • Kukula kwa gawolo:Magawo akuluakulu amatha kuzizira pang'onopang'ono panthawi ya kutentha, kuchepetsa kuuma.

  • Kumaliza pamwamba:Zomaliza zolimba zimatha kukhala ngati zolimbikitsa kupsinjika.

  • Machining ntchito:Kupanga kolakwika kungayambitse kupsinjika.

  • Kuwongolera kutentha:Kuzimitsa bwino ndi kutentha kumakhudzanso mphamvu yomaliza.

At sakysteel, timagwiritsa ntchito kuwongolera kokhazikika pamankhwala otenthetsera komanso kukonza makina kuti tiwonetsetse kuti zinthu zili bwino komanso zokhazikika pazogulitsa zathu zonse zazitsulo za 4140.

Mayeso ndi Certification

Kulimba kwamphamvu kumayesedwa pogwiritsa ntchito amakina oyesera onse (UTM)kutsatira miyezo ya ASTM kapena ISO. Chitsanzo chachitsulo chimatambasulidwa mpaka chimasweka, ndipo zotsatira zake zimalembedwa.

ZonsesakysteelZida zachitsulo za 4140 zitha kuperekedwa ndi:

  • EN 10204 3.1 satifiketi

  • Malipoti oyesera zamakina

  • Zambiri zamagulu a Chemical

Izi zimatsimikizira kuwonekera kwathunthu komanso kutsata miyezo yamakampani.

Malingaliro Omaliza

4140 aloyi zitsulondi imodzi mwazitsulo zosunthika komanso zolimba zomwe zimapezeka pamsika wapadziko lonse lapansi. Ndi mphamvu yolimba yopitilira 1000 MPa m'malo othandizidwa, imakwaniritsa zofunikira pamapangidwe, makina, ndi zida.

Pamene mphamvu, kulimba, ndi magwiridwe antchito ndizofunikira kwambiri,4140 amapereka-ndisakysteelzimatsimikizira kuti mumalandira kokha zinthu zapamwamba kwambiri, zoyesedwa ndi zovomerezeka kuti mukhale ndi mtendere wamumtima.
