SAE4340 40CrNiMoA Aloyi Yopanda Zitsulo Chitoliro

SAE4340 40CrNiMoA Aloyi Chitoliro Chopanda Chitsulo Chowonetsedwa

Kufotokozera Kwachidule:

40CrNiMoA alloy alloy zitsulo chitoliro ndi chitoliro chachitsulo champhamvu kwambiri, cholimba kwambiri.Mapangidwe ake makamaka amaphatikizapo chromium, faifi tambala, molybdenum ndi pang'ono mpweya, pakachitsulo, manganese ndi zinthu zina, kupyolera mu kuchuluka kwapadera ndi njira kutentha kutentha, ali ndi kukana dzimbiri bwino ndi kutentha kutentha ntchito.Chifukwa cha makina ake abwino kwambiri komanso magawo osiyanasiyana ogwiritsira ntchito, amagwiritsidwa ntchito kwambiri m'mafakitale ambiri.

Munda Wofunsira

1. M'makampani a petrochemical, angagwiritsidwe ntchito popanga zida zazikulu monga zotengera zothamanga kwambiri, zowonongeka, zowonongeka, ndi zina zotero, zomwe zimatha kupirira kutentha kwapamwamba, kupanikizika kwakukulu ndi zofalitsa zowonongeka.

2. M'makampani amagetsi amagetsi, angagwiritsidwe ntchito popanga zigawo za jenereta, ma boilers, makina opangira nthunzi ndi zipangizo zina, zomwe zimatha kupirira katundu wambiri komanso kutentha kwambiri.

3. Pamalo oyendetsa ndege, angagwiritsidwe ntchito popanga zinthu zofunika kwambiri monga zida zoikira ndege ndi ma fuselage kuti apititse patsogolo chitetezo ndi ntchito za ndege.

Kuphatikiza apo, mapaipi achitsulo a 40CrNiMoA angagwiritsidwenso ntchito popanga zida zazikulu zamagalimoto, zombo, njanji ndi mafakitale ena kuti apititse patsogolo kudalirika kwazinthu komanso kudalirika.

Kufotokozera kwa Chithandizo cha Kutentha

Kuzimitsa kutentha: 850 ºC;zoziziritsa kukhosi: mafuta;kutentha kwapakati: 600 ºC;ozizira: madzi, mafuta.

Mkhalidwe Wotumizira

Kupereka chithandizo cha kutentha (normalizing, annealing kapena high heat tempering) kapena palibe kutentha kwa kutentha, chikhalidwe cha kubereka chiyenera kuwonetsedwa mu mgwirizano.
