SAE4340 Chitsulo Round Bar ASTM4340 Ndodo yachitsulo
Mawonekedwe
Zida za 4340 zitsulo bar ndi aloyi structural chitsulo.Zofanana German DIN zitsulo kalasi 36CrNiMo4 , French NF muyezo 40NCD3, Japanese JIS muyezo SNCM439, British BS muyezo 816M40, American SAE/ASTM4340, American UNS muyezo G43400，China Standard 40CrNiMoA.
SAE4340 amadziwika kuti aloyi structural chitsulo kapena gulu zitsulo.Chitsulocho chimakhala ndi faifi tambala pakati pa 1.65 ndi 2.00, chomwe chili ndi mphamvu zambiri, kulimba, kulimba kwambiri, komanso kukhazikika polimbana ndi kutentha kwambiri.Komabe, ili ndi chidwi chachikulu ndi mawanga oyera komanso kupsa mtima.Kusawerengeka bwino, komwe kumafunikira kutentha kwambiri kusanayambe kuwotcherera, kuchepetsa nkhawa mutatha kuwotcherera, ndikugwiritsanso ntchito mukatenthetsa.
ZOYENERA: ASTM A29/A29M-2012 kapena SAE J404

Kutentha mankhwala specifications
Kuzimitsidwa pa 850 ℃, mafuta utakhazikika;Kutentha pa 600 ℃, madzi utakhazikika, mafuta utakhazikika.
Kugwiritsa ntchito
Amagwiritsidwa ntchito popanga magawo ofunikira okhala ndi mphamvu zambiri komanso mapulasitiki abwino, komanso popanga magawo ofunikira okhala ndi zofunikira zapadera pambuyo pa chithandizo cha nitrate:
-Makina olemera okhala ndi ma shaft olemetsa kwambiri
- Wheel shaft ndi m'mimba mwake kuposa 250mm
-Nthawi ya rotor ya helikopita
-Mphepete mwa turbine shaft, masamba, ndi zida zonyamula katundu wambiri za injini ya turbojet
- Zomangira za Crankshaft, magiya, ndi zina.
Phukusi
1.Ndi mitolo, mtolo uliwonse wolemera pansi pa matani atatu, kwa ang'onoang'ono akunjam'mimba mwake, mtolo uliwonse wokhala ndi zitsulo 4 - 8.
2.20 mapazi chidebe muli gawo, kutalika pansi 6000mm
3.40 mapazi chidebe lili mbali, kutalika pansi 12000mm
4.Ndi chotengera chochuluka, Freight charge ndi yotsika ndi katundu wambiri, komanso wamkuluzolemera saizi sangakhoze yodzaza mu muli akhoza kutumiza ndi chochuluka katundu
