Kodi 4140 ndi mtundu wanji wa chitsulo?

Chitsulo cha 4140 ndi chitsulo chodziwika bwino cha alloy chomwe chimadziwika ndi mphamvu zake, kulimba kwake, komanso kusinthasintha kwake. Ndi cha m'banja la zitsulo za chromium-molybdenum, zomwe zimapangitsa kuti chikhale chosankhidwa bwino kwambiri pamafakitale. Mainjiniya, opanga zinthu, ndi opanga amagwiritsa ntchito kwambiri chitsulochi pazinthu zonse kuyambira zida zamagalimoto mpaka zida zama makina.

Mu nkhani iyi ya SEO, sakysteel ikupereka chithunzithunzi chokwanira cha4140 chitsulo, kuphatikizapo kapangidwe kake ka mankhwala, mphamvu zake zamakaniko, njira zochizira kutentha, ndi ntchito zofala.

Gulu la Zitsulo 4140

4140 ndi chitsulo chopanda aloyi chomwe chimagwera pansi pa dongosolo la SAE-AISI. Chimadziwikanso kutiAISI 4140, EN19 (ku Ulaya)ndiSCM440 (ku Japan)Dzina lakuti “4140” limatanthauza kuchuluka kwa aloyi:

  • “41” ikutanthauza chitsulo cha chromium-molybdenum

  • "40" ikuyimira kuchuluka kwa kaboni komwe kukuyembekezeka (0.40%)

Chitsulo cha 4140 si chitsulo chosapanga dzimbiri, chifukwa chilibe chromium yokwanira kuti chiteteze dzimbiri. M'malo mwake, chimayamikiridwa chifukwa cha mphamvu zake zamakaniko komanso kuuma kwake pambuyo potenthedwa.

Kapangidwe ka Mankhwala a Chitsulo cha 4140

Kapangidwe ka mankhwala ka 4140 ndi komwe kamapangitsa kuti ikhale ndi mphamvu zowonjezera. Mitundu yanthawi zonse imaphatikizapo:

  • Kaboni (C):0.38% – 0.43%

  • Chromium (Cr):0.80% – 1.10%

  • Manganese (Mn):0.75% – 1.00%

  • Molybdenum (Mo):0.15% – 0.25%

  • Silikoni (Si):0.15% – 0.35%

  • Phosphorus (P):≤ 0.035%

  • Sulfure (S):≤ 0.040%

Zinthu zimenezi zimagwirira ntchito limodzi kuti ziwonjezere kulimba, kukana kuwonongeka, komanso kulimba, zomwe zimapangitsa kuti 4140 ikhale chinthu chofunikira kwambiri pazida zamakanika zomwe zimafuna mphamvu zambiri.

Katundu wa Makina a Chitsulo cha 4140

4140 imapereka mitundu yosiyanasiyana ya zinthu zamakanika, makamaka mutatentha bwino. Izi zikuphatikizapo:

  • Kulimba kwamakokedwe:Kufikira 1100 MPa (160 ksi)

  • Mphamvu Yopereka:Pafupifupi 850 MPa (123 ksi)

  • Kutalika pa nthawi yopuma:Pafupifupi 20%

  • Kuuma:Kawirikawiri 197 mpaka 235 HB mu mkhalidwe wophimbidwa, mpaka 50 HRC mutatha kuzimitsa ndi kutenthetsa.

Mitengo iyi imatha kusiyana malinga ndi mawonekedwe a chitsulo (mpiringidzo, mbale, chopangidwa) ndi momwe chimathandizira kutentha.

Kutentha kwa Chitsulo cha 4140
