Fausia ma Togafitiga vevela
Masini
AISI 4140 u'amea uamea e lelei machinability i le tulaga annealed.
Fausia
AISI 4140 u'amea uamea e maualuga ductility. E mafai ona fausia i le faʻaaogaina o metotia masani i le tulaga faʻafefe. E manaʻomia le tele o le mamafa poʻo le malosi mo le fausiaina ona e sili atu le malosi nai lo uʻamea kaponi mama.
Uelo
AISI 4140 uʻamea uʻamea e mafai ona uelo e faʻaaoga uma auala masani. Ae ui i lea, o mea faʻainisinia o lenei uʻamea o le a aʻafia pe a faʻapipiʻiina i le tulaga vevela, ma e tatau ona faia le faʻaogaina o le vevela pe a maeʻa.
Togafitiga vevela
AISI 4140 u'amea uamea fa'avevela i le 845°C (1550°F) sosoo ai ma le tineia i le suauu. A'o le'i fa'ama'a'aina, e mafai ona fa'amanino e ala i le fa'avelaina i le 913°C (1675°F) mo se vaitaimi umi, soso'o ai ma le fa'amalieina o le ea.
Fa'ailogaina
AISI 4140 u'amea u'amea ua faia i le 926 i le 1205°C (1700 i le 2200°F)
Galulue vevela
AISI 4140 u'amea uamea e mafai ona vevela galue i le 816 i le 1038 ° C (1500 i le 1900 ° F)
Galulue malulu
AISI 4140 u'amea u'amea e mafai ona malulu galue e faaaoga auala masani i le tulaga annealed.
Fa'asusu
AISI 4140 u'amea u'amea ua fa'amauina i le 872°C (1600°F) soso'o ai ma le fa'alili malie i totonu o le ogaumu.
Fa'aitaita
AISI 4140 u'amea uamea e mafai ona fa'afefe i le 205 i le 649°C (400 i le 1200°F) e fa'atatau i le tulaga ma'a'a mana'omia. O le maaa o le uamea e mafai ona faateleina pe afai e maualalo le vevela. Mo se faʻataʻitaʻiga, e mafai ona maua le malosi faʻamalosi o le 225 ksi e ala i le faʻafefe i le 316°C (600°F), ma le malosi faʻamalosi o le 130 ksi e mafai ona maua i le faʻafefe i le 538°C (1000°F).
Fa'amaaa
AISI 4140 uʻamea uamea e mafai ona faʻamaʻaʻaina e ala ile galue malulu, poʻo le faʻamafanafanaina ma le tineia.
