Guhimba no kuvura ubushyuhe
Imashini
AISI 4140 alloy ibyuma bifite imashini nziza muburyo bwa annealed.
Gushiraho
AISI 4140 ibyuma bivanze bifite ihindagurika ryinshi. Irashobora gushirwaho hakoreshejwe tekinoroji isanzwe muburyo bwa annealed. Bisaba imbaraga nyinshi cyangwa imbaraga zo gukora kuko birakomeye kuruta ibyuma bya karubone bisanzwe.
Gusudira
AISI 4140 ibyuma bivanze birashobora gusudwa hakoreshejwe tekinoroji isanzwe. Nyamara, imiterere yubukanishi bwiki cyuma izagira ingaruka niba isuditswe muburyo butunganijwe nubushyuhe, kandi hagomba gukorwa ubuvuzi bwa nyuma ya weld.
Kuvura Ubushuhe
Icyuma cya AISI 4140 gishyuha kuri 845 ° C (1550 ° F) hagakurikiraho kuzimya amavuta. Mbere yo gukomera, irashobora kuba ibisanzwe mu kuyishyushya kuri 913 ° C (1675 ° F) igihe kirekire, igakurikirwa no gukonjesha ikirere.
Guhimba
AISI 4140 ibyuma bivangwa na 926 kugeza 1205 ° C (1700 kugeza 2200 ° F)
Gukora Bishyushye
AISI 4140 ibyuma bivanze birashobora gushyuha bikorerwa kuri 816 kugeza 1038 ° C (1500 kugeza 1900 ° F)
Gukora Ubukonje
AISI 4140 ibyuma bivanze birashobora gukonja bikoreshejwe hakoreshejwe uburyo busanzwe muburyo bwa annealed.
Annealing
AISI 4140 ibyuma bivangwa n'amavuta bifatirwa kuri 872 ° C (1600 ° F) bigakurikirwa no gukonja buhoro mu itanura.
Ubushyuhe
AISI 4140 ibyuma bivanze birashobora gushyuha kuri 205 kugeza 649 ° C (400 kugeza 1200 ° F) bitewe nurwego rwifuzwa. Ubukomezi bwibyuma burashobora kwiyongera niba bufite ubushyuhe buke. Kurugero, imbaraga zingana na 225 ksi zishobora kugerwaho nubushyuhe kuri 316 ° C (600 ° F), naho imbaraga zingana na 130 ksi zishobora kugerwaho nubushyuhe kuri 538 ° C (1000 ° F).
Gukomera
AISI 4140 ibyuma bivanze birashobora gukomera nakazi gakonje, cyangwa gushyushya no kuzimya.
