AISI 4140 SCM440 DIN 42CrMo4 1.7225 Forged Alloy Steel Round Bar
Tsatanetsatane wa Zamalonda
AISI 4140 imatanthauzidwa ngati chitsulo chochepa cha alloy chomwe chili ndi 1% Cr-Mo monga kulimbikitsa ma alloy elements.Poyerekeza ndi AISI 4130, ili ndi mpweya wochuluka wa carbon wokhala ndi mphamvu zabwino, zolimba, zowononga ndi zotsutsana ndi kutentha, koma AISI 4140 nthawi zambiri imaperekedwa mozimitsidwa ndi kupsya mtima ndi kuuma 28-32HRC.
4140 ili ndi mphamvu zambiri, kulimba mtima, kulimba, komanso kusinthika pakuzimitsa.Lili ndi mphamvu zokwawa kwambiri komanso mphamvu zopirira pa kutentha kwakukulu.Amagwiritsidwa ntchito popanga ma forging omwe amafunikira mphamvu zapamwamba komanso zigawo zazikulu zozimitsidwa komanso zotentha kuposa zitsulo za 4135, monga magiya akuluakulu oyendetsa magalimoto, magiya opititsa patsogolo, ma axles akumbuyo, ndodo zolumikizira ndi ma tapi a masika omwe amadzaza kwambiri.
