Machineability
AISI 4140 alloy steel muaj kev ua haujlwm zoo hauv cov txheej txheem annealed.
tsim
AISI 4140 alloy steel muaj cov ductility siab. Nws tuaj yeem tsim tau siv cov txheej txheem pa hauv qhov kev mob annealed. Nws yuav tsum tau ntau lub siab los yog quab yuam rau kev tsim vim nws yog tawv dua li cov pa roj carbon steels.
Vuam
AISI 4140 alloy hlau tuaj yeem siv tau los ntawm kev siv txhua yam txuj ci. Txawm li cas los xij, cov khoom siv ntawm cov hlau no yuav raug cuam tshuam yog tias nws tau welded nyob rau hauv qhov kev kho cua sov, thiab tom qab vuam cua sov yuav tsum tau ua.
Kev kho cua sov
AISI 4140 alloy steel yog rhuab ntawm 845 degree (1550 degree F) ua raws li los ntawm quenching hauv roj. Ua ntej hardening, nws tuaj yeem ua tau zoo los ntawm cua sov ntawm 913 degree (1675 degree F) rau lub sijhawm ntev tom qab cua txias.
Forging
AISI 4140 alloy steel yog forged ntawm 926 txog 1205 degree (1700 txog 2200 degree F)
Kub Ua Haujlwm
AISI 4140 alloy hlau tuaj yeem ua haujlwm kub ntawm 816 txog 1038 degree (1500 txog 1900 degree F)
Ua haujlwm txias
AISI 4140 alloy hlau tuaj yeem ua haujlwm txias los ntawm kev siv cov txheej txheem hauv cov txheej txheem annealed.
Annealing
AISI 4140 alloy steel yog annealed ntawm 872 degree (1600 degree F) ua raws li maj mam txias hauv lub cub tawg.
Tempering
AISI 4140 alloy hlau tuaj yeem tempered ntawm 205 txog 649 degree (400 txog 1200 degree F) nyob ntawm seb qhov xav tau hardness qib. Lub hardness ntawm cov hlau tuaj yeem nce ntxiv yog tias nws muaj qhov kub thiab txias. Piv txwv li, lub zog tensile ntawm 225 ksi cab yuav ua tiav los ntawm tempering ntawm 316 degree (600 degree F), thiab lub zog tensile ntawm 130 ksi tuaj yeem ua tiav los ntawm tempering ntawm 538 degree (1000 degree F).
Hardening
AISI 4140 alloy steel tuaj yeem ua kom tawv los ntawm kev ua haujlwm txias, lossis cua sov thiab quenching.
