  4. Fatigue limit - Wikipedia

    Fatigue limit, endurance limit, and fatigue strength are all expressions used to describe a property of materials: the amplitude (or range) of cyclic stress that can be applied to the material without causing fatigue failure. Ferrous alloys and titanium alloys have a distinct limit, called the endurance limit, which is the amplitude of completely reversed bending stress below which there buy 4130 steel endurance limit
