4140 steel endurance limit Introduction

Steels - Endurance Limits and Fatigue Stress

1 MPa = 106 Pa = 1 N/mm2= 145.0 psi (lbf/in2) Fatigue limit, endurance limit, and fatigue strength are used to describe the amplitude (or range) of cyclic stress that can be applied to the material without causing fatigue failure.

The fatigue limit of AISI 4140 steel increases almost 18% with increasing depth of cut from 0.4 to 1.2 mm. Further increase in depth of cut to 2.0 mm has no pronounced influence on the average fatigue limit of this steel. However, the dispersion of the fatigue limit increases with increasing depth of cut.

What is Endurance Limit (Se)? - Definition from …

Endurance limit (Se) is the stress level below which a specimen can withstand cyclic stress indefinitely without exhibiting fatigue failure. Rigid, elastic, low damping materials such as thermosetting plastics and some crystalline thermoplastics do not exhibit an endurance limit. On the other hand, steel exhibits a high endurance limit.
