20CrMnMo yotentha yozungulira zitsulo zozungulira

Good matenthedwe processing ntchito, normalizing pambuyo ntchito bwino kudula, pambuyo kuzimitsa ndi tempering ndi zabwino makina katundu ndi otsika kutentha zotsatira toughness, pambuyo carburizing ndi mkulu flexural mphamvu ndi kuvala kukana, koma weldability osauka, kuti bwino anatenthetsa pamaso kuwotcherera, pambuyo kuwotcherera ayenera khala wokwiya. Amagwiritsidwa ntchito popanga zofunikira za kuuma kwapamwamba kwambiri, kukana kwabwino kovala ndikofunikira, monga magiya, ndodo ya camshafts,

Kukula kwachitsanzo: Kukula kwachitsanzo ndi 15mm movutikira
Chithandizo cha kutentha ndi mawonekedwe a microstructure:
Kutentha mankhwala specifications: kuzimitsa 850 ℃, mafuta kuzirala; kutentha 200 ℃, madzi utakhazikika, mpweya utakhazikika.
Microstructure: tempered martensite.
Mkhalidwe woperekera: kutenthetsa chithandizo (kuwotcha, kutenthetsa kapena kutenthetsa) kapena popanda chithandizo cha kutentha, chikhalidwe chobereka chiyenera kufotokozedwa mu mgwirizano.
