Kupanga ndi Kuchiza Kutentha
Kuthekera
AISI 4140 alloy chitsulo ali ndi machinability wabwino mu chikhalidwe annealed.
Kupanga
AISI 4140 aloyi chitsulo ali ndi ductility mkulu. Ikhoza kupangidwa pogwiritsa ntchito njira zodziwika bwino mu chikhalidwe cha annealed. Zimafunika kukakamiza kwambiri kapena kukakamiza kuti apange chifukwa ndi cholimba kuposa zitsulo za carbon.
Kuwotcherera
AISI 4140 alloy chitsulo amatha kuwotcherera pogwiritsa ntchito njira zonse wamba. Komabe, zida zamakina zachitsulo ichi zidzakhudzidwa ngati zimatenthedwa ndi kutentha, ndipo chithandizo cha kutentha kwapambuyo pa weld chiyenera kuchitidwa.
Kutentha Chithandizo
Chitsulo cha AISI 4140 chimatenthedwa pa 845 ° C (1550 ° F) ndikutsatiridwa ndi mafuta. Isanaumitsidwe, imatha kusinthidwa ndikuyitentha pa 913 ° C (1675 ° F) kwa nthawi yayitali, ndikutsatiridwa ndi kuziziritsa kwa mpweya.
Kupanga
AISI 4140 alloy zitsulo amapangidwa pa 926 mpaka 1205 ° C (1700 mpaka 2200 ° F)
Hot Working
AISI 4140 aloyi zitsulo akhoza kutentha ntchito pa 816 kuti 1038 ° C (1500 mpaka 1900 ° F)
Ntchito Yozizira
AISI 4140 alloy zitsulo zitha kuzizira ntchito pogwiritsa ntchito njira wamba mu chikhalidwe cha annealed.
Annealing
AISI 4140 alloy zitsulo amatenthedwa pa 872 ° C (1600 ° F) kenako ndikuziziritsa pang'onopang'ono mu ng'anjo.
Kutentha
AISI 4140 alloy zitsulo zimatha kutenthedwa pa 205 mpaka 649 ° C (400 mpaka 1200 ° F) kutengera kuuma komwe mukufuna. Kuuma kwachitsulo kumatha kuwonjezeka ngati kuli ndi kutentha kochepa. Mwachitsanzo, mphamvu yamphamvu ya 225 ksi ingapezeke mwa kutenthetsa pa 316 ° C (600 ° F), ndipo mphamvu ya 130 ksi ingapezeke mwa kutentha kwa 538 ° C (1000 ° F).
Kuwumitsa
Chitsulo cha AISI 4140 chikhoza kuumitsidwa ndi kuzizira, kapena kutentha ndi kuzimitsa.
