The fatigue limit of steel is around ____ times the ultimate tensile strength.

The fatigue limit of steel is around ____ times the ultimate tensile strength. Correct Answer 0.5

The fatigue limit is different for different materials. For the material steel, the fatigue limit is around 0.5 of its ultimate tensile strength. For materials that are non-ferrous in nature, the fatigue limit can 0.3 or 0.4 of its ultimate tensile strength.
