Cr-Mo vs Cr-V Impact Sockets.- Thorium Tools

Jan 19,2020·Cr-Mo is a heat-hardened steel alloy,with the inclusion of molybdenum that gives the alloy a property of toughness and flexibility.Cr-Mo will absorb percussive impact better than Cr-V without being brittle.Over time Cr-Mo sockets may stretch and lose their shape,but they are less likely to shatter and cause injury.CrMoV - upmet10 rows·CrMov is a low alloy ferritic steel.Also known as a creep resisting alloy,this material is Degradation of mechanical properties of Cr-Mo-V andIn Cr-Mo-V steel,the loss in strength was accompanied by an improvement in ductility and toughness.Despite softening of 2.25Cr-1Mo steel in service,elevated temperature exposure resulted in a marked decrease in ductility and toughness.The loss of toughness in this steel was in part irreversible.
