Fabricatio et calor curatio
Machinability
AISI 4140 mixtura chalybs bonam machinabilitatem habet in conditione annata.
formans
AISI 4140 stannum ensem alte ductilis. Formari potest utens technicae artis conventionales in annata condicione. Plus pressionis seu vim requirit ad formandum quia durior est quam chalybeis campi carbonis.
Welding
AISI 4140 mixtura chalybs conflari potest omnibus technicis conventionalibus adhibitis. Attamen proprietatibus mechanicis huius chalybis afficietur si iuncta sit in condicionem caloris tractatam, et curatio caloris post iuncta facienda.
Calor treatment
AISI 4140 mixtura chalybis calefacta 845°C (1550°F) in oleo restinguendo sequitur. Ante obdurationem per longum tempus normali potest calefaciendo in 913°C (1675°F), sequitur refrigeratio aeris.
Forging
AISI 4140 mixtura chalybs fictum est sub 926 ad 1205°C (1700 ad 2200°F)
Calidum Operationis
AISI 4140 mixtura ferri potest fervere operata ad 816 ad 1038°C (1500 ad 1900°F)
Frigus Operationis
AISI 4140 mixtura chalybs frigida utens modos conventionales in conditione annata fieri potest.
Annealing
AISI 4140 mixtura chalybs subiungitur in 872°C (1600°F) sequitur lente in fornace refrigerans.
Temperatio
AISI 4140 mixtura chalybs temperari potest ab 205 ad 649°C (400 ad 1200°F) secundum gradum duritiae desideratae. Duritia ferri augeri potest si temperaturam inferiorem habeat. Exempli gratia: tensile robur 225 ksi perfici potest temperando in 316°C (600°F), et distrahens robur 130 ksi potest fieri temperando in 538°C (1000°F).
Hardening
AISI 4140 mixtura chalybs durari potest frigore operationis, seu calefaciendi et exstinguendi.
