Wax-soo-saarka iyo daawaynta kulaylka
Mashiinka
AISI 4140 birta daawaha ah waxay leedahay mashiin wanaagsan oo ku jira xaaladda la jeexjeexay.
Samaynta
AISI 4140 birta aluminiumku waxay leedahay ductility sare. Waxaa la samayn karaa iyadoo la adeegsanayo farsamooyinka caadiga ah ee xaaladda la daboolay. Waxay u baahan tahay cadaadis ama xoog badan si loo sameeyo sababtoo ah way ka adag tahay birta kaarboonka ee cad.
alxanka
AISI 4140 birta aluminiumka ah waxaa lagu alxan karaa iyadoo la adeegsanayo dhammaan farsamooyinka caadiga ah. Si kastaba ha ahaatee, sifooyinka farsamada ee birtan ayaa saameyn doona haddii lagu dhejiyo xaalada kulaylka, iyo daaweynta kuleylka ka dib alxanka waa in la sameeyaa.
Daawaynta kulaylka
AISI 4140 steel alloy waxa lagu kululeeyaa 845°C (1550°F) oo ay ku xigto daminta saliidda. Kahor inta aan la adkeynin, waxaa caadi lagu noqon karaa in lagu kululeeyo 913°C (1675°F) muddo dheer, oo ay ku xigto qaboojinta hawada.
Been abuurasho
AISI 4140 birta daawaha waxaa lagu been abuurtay 926 ilaa 1205 ° C (1700 ilaa 2200 ° F)
Shaqo Kulul
AISI 4140 birta alloy waxay noqon kartaa mid kulul oo laga shaqeyn karo 816 ilaa 1038 ° C (1500 ilaa 1900 ° F)
Shaqada Qabow
AISI 4140 birta daawaha ah waxaa lagu shaqeyn karaa qabow iyadoo la adeegsanayo hababka caadiga ah ee xaaladda la daboolay.
Annealing
AISI 4140 birta daawaha waxa lagu dahaadhay 872°C (1600°F) oo ay ku xigto si tartiib ah foornada.
xanaaqsan
AISI 4140 birta daawaha ah waxa lagu kululayn karaa 205 ilaa 649°C (400 ilaa 1200°F) taas oo ku xidhan heerka adkaanta la doonayo. Adkeydka birta waa la kordhin karaa haddii ay leedahay heerkul heerkul hoose. Tusaale ahaan, awoodda xajinta ee 225 ksi waxaa lagu gaari karaa heerkulka 316°C (600°F), awoodda xajinta ee 130 ksi waxaa lagu gaari karaa heerkulka 538°C (1000°F).
Adkeyn
AISI 4140 birta daawaha ah waxaa lagu adkeyn karaa qabow shaqayn, ama kululaynta iyo deminta.
