Fabrication thiab Thaum tshav kub kub kho

Machineability

AISI 4140 alloy steel muaj kev ua haujlwm zoo hauv cov txheej txheem annealed.

Kev 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 welded siv tag nrho cov txheej txheem pa. Txawm li cas los xij, cov khoom siv ntawm cov hlau no yuav raug cuam tshuam yog tias nws yog welded nyob rau hauv qhov kev kho cua sov, thiab kev kho cua sov tom qab vuam yuav tsum tau ua.

Kev kho cua sov

AISI 4140 alloy steel yog rhuab ntawm 845 ° C (1550 ° F) tom qab quenching hauv roj. Ua ntej hardening, nws tuaj yeem ua tau zoo los ntawm cua sov ntawm 913 ° C (1675 ° F) rau lub sijhawm ntev, ua raws li cua txias.

Forging

AISI 4140 alloy steel yog forged ntawm 926 txog 1205 ° C (1700 txog 2200 ° F)

Kub Ua Haujlwm

AISI 4140 alloy hlau tuaj yeem ua haujlwm kub ntawm 816 txog 1038 ° C (1500 txog 1900 ° F)

Ua haujlwm txias

AISI 4140 alloy steel 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 ° C (1600 ° F) ua raws li maj mam txias hauv lub cub tawg.

Tempering

AISI 4140 alloy hlau tuaj yeem tempered ntawm 205 txog 649 ° C (400 txog 1200 ° F) nyob ntawm 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 tuaj yeem ua tiav los ntawm tempering ntawm 316 ° C (600 ° F), thiab tensile lub zog ntawm 130 ksi tuaj yeem ua tiav los ntawm tempering ntawm 538 ° C (1000 ° F).
