AISI 4340 (34CrniMo6)ni chisulo chapachanya chomene icho chikupangika na chisulo chakupangika na nickel, chromium, na molybdenum. Likumanyikwa chifukwa cha .Kulimba kwapaderana nkhongono zakupanga nkhongono zapachanya mu nyengo yakuchizgika na kutentha- uku ŵakusunga nkhongono ziwemi zakukanizga kutopa.
Kuyaniskakufika pa 4140, kusazgirapo kwa .Nikeli (1.5%wakupeleka 4340 wapachanyaKukhoma Kwakuzika. This means it can achieve uniform hardness from the surface to the center, even in large cross-sections (e.g., shafts >150 mm mu msinkhu). Ni vinthu vyakumanyikwa vya vigaŵa ivyo vikusuzgika chomene mu ndege, mafuta & gasi kuboola, na makina ghakuzirwa .ry apo kutondeka nkhwakusankha yayi.

Vinthu vikuruvikuru and Uwemi
- Kukhoma kwakuya:Chifukwa cha Nickel, 4340 yingakhozgeka kwizira mu-na -kupitira mu vigaŵa vikuruvikuru, apo 4140 yingakhozgeka waka pa mtunda mu vingwe vyakukhora.
- Kulimba kwakukhwaskika chomene:Kuwoneska ductility yiwemi chomene na kukana katundu wakugwedezeka, nanga ni pa nyengo yakuzizima ya sub-zero.
- Nkhongono zapachanya:Kungaŵa kutentha -kuchizgika ku nkhongono zakuzizwiska zakukhozga (mpaka 1500 MPa / 220 ksi) uku ŵakusunga ductility yiwemi kuluska vitsulo vinyake vinandi pa mlingo uwu wa nkhongono.
- Kulimbana na Kutopa:Ntchiwemi chomene ku vigaŵa vyakunyamulika nga ni crankshafts na magiya ghakukhira.
- EN24 Kuyana waka:34CrNiMo6 yithu yikuyana na yakumanyikwa .EN24grade iyo yikugwiriskirika nchito comene mu misika ya UK na Commonwealth.
Mapulogalamu ghakumanyikwa
4340 / 34CrNiMo6 yikugwiriskirika nchito apo 4140 njakukhora yayi panji njakukhora mwakukwana:
Ndege
Vigaŵa vya magiya ghakukhira ndege, vigaŵa vya kapangilo, na shafuti za ndege ya helikopita.
Kuchimbira kwa magalimoto
Ma crankshaft ghakugwira ntchito makora, ndodo zakulumikizga, na ma axle ghakutumizga.
Makina Ghakuzirwa
Ma shaft ghakuru gha ma turbine gha mphepo, ghakuphwanya malibwe, na mphero zakuguzira.
Mafuta na Gasi
Vipangizo vyakuboola pasi, makolala ghakuboola, na mavavu ghakukhozga chomene.
Mafakitale gha nkhungu
Kugwiriskira ncito nga ni vikumba vyakuŵikamo nkhungu vya nkhungu zikuru za pulasitiki izo zikukhumbikwira nkhongono zakukhozga.
Mafumbo ghakufumbika
Q1: Kasi ni mphambano yikuru wuli pakati pa 4140 na 4340 zitsulo?
A1: Nickel. 4340 contains ~1.8% nickel, while 4140 contains none. This nickel gives 4340 much higher toughness and allows it to harden deeper in thick sections. If your part is thick (>100 mm) ndipo wakukhumba nkhongono zapachanya, sankhani 4340.
F2: Kasi 34CrNiMo6 njakuyana waka na 4340?
A2: Iwo ŵakuyana chomene kweni ŵakuyana yayi . 34CrNiMo6 (1.6582) ni European (DIN) standard, iyo kanandi yili na carbon yichoko waka kweni chromium yikuru kuluska AISI 4340. Kweni, pa ntchito zinandi zakuzirwa -, ŵakuwoneka kuti ŵakusinthana ntchito equi.
Q3: Kasi 4340 chisulo nchakusuzga kupanga makina?
A3: Vikuthemba pa umo vinthu viliri. Mu annealed boma, iyo makina mwakukwana makora. Mu mtundu wakukhora (QT) (mwachiyelezgero, 30-35 HRC), kupanga makina nkhwakusuzga chomene ndipo kukukhumbikwira vipangizo vyakukhora, kweni vikupangiska kuti paŵe kumalizga makora pa malo.
Q4: Kasi ningawotcha chisulo cha 4340?
A4: Kuwotcha nkhwakusuzga. Chifukwa chakuti 4340 yili na aloyi yinandi, yili na ngozi yikuru chomene yakuti yingaphulika pa nyengo yakuwotcha. Iwo ukukhumbikwira kutentha kwakukwana (200-300℃) na kuzizima kwakulongozgeka panyuma pa kuwotcha. Welding mu chikhalidwe wolimbikitsa chomene wakukhuŵazga.
