Even though they seem as static in press, those parts are exposed to fatigue the most. Tie rods must be tempered and produced from a material that has high fatigue strength. (4140)
DESCRIPTION OF THE MATERIAL
The chemical compositions are suitable for hardening by carbon content and at the end of the treatment process shows high toughness properties under certain loads alloy structural steels. The inducibility is good.
USAGE AREA OF THE MATERIAL
Used for producing automobile and plane, crankshaft, axle shaft and housing, spline shaft and similar parts whose ductility is high, besides, they are used for producing gear and wheel.
