Ukwenziwa kanye Nokwelashwa Kokushisa
Ukusebenziseka kalula
I-AISI 4140 insimbi ye-alloy ine-machinability enhle esimweni se-annealed.
Ukubumba
I-AISI 4140 alloy steel ine-ductility ephezulu. Ingakhiwa kusetshenziswa amasu ajwayelekile esimweni esine-annealed. Idinga ingcindezi eyengeziwe noma amandla okwenza ngoba iqinile kunezinsimbi ze-carbon.
Ukushisela
I-AISI 4140 insimbi ye-alloy ingafakwa nge-welded kusetshenziswa wonke amasu ajwayelekile. Kodwa-ke, izakhiwo zemishini zale nsimbi zizothinteka uma zishiswa esimweni sokushisa, futhi ukwelashwa kokushisa kwe-post-weld kufanele kwenziwe.
Ukwelashwa Kokushisa
I-AISI 4140 alloy steel ifudunyezwa ku-845°C (1550°F) kulandele ukucisha emafutheni. Ngaphambi kokuqina, ingahle ijwayeleke ngokuyishisisa ku-913°C (1675°F) isikhathi eside, kulandele ukupholisa komoya.
Ukuqamba
I-AISI 4140 alloy steel yenziwe ngo-926 kuya ku-1205 ° C (1700 kuya ku-2200 ° F)
Kuyashisa Ukusebenza
I-AISI 4140 ingxubevange yensimbi ingashisa kusetshenzwe ku-816 kuya ku-1038°C (1500 kuya ku-1900°F)
Ukusebenza Okubandayo
I-AISI 4140 insimbi ye-alloy ingabanda isetshenziswe kusetshenziswa izindlela ezijwayelekile esimweni esifakwe emanzini.
Anealing
I-AISI 4140 alloy steel ifakwa ku-872°C (1600°F) kulandele ukupholisa kancane esithandweni.
Ukuthukuthela
I-AISI 4140 ingxubevange yensimbi ingashiswa ku-205 kuya ku-649°C (400 kuya ku-1200°F) kuye ngezinga lobulukhuni obufunayo. Ubulukhuni bensimbi bungakhuphuka uma bunokushisa okuphansi kokushisa. Isibonelo, amandla okuqina angu-225 ksi angafinyelelwa ngokushisa ku-316°C (600°F), futhi amandla okuqina angu-130 ksi angafinyelelwa ngokushisa ku-538°C (1000°F).
Ukuqina
I-AISI 4140 alloy steel ingaqiniswa ngokusebenza okubandayo, noma ukushisa nokucisha.
