Steels - Endurance Limits and Fatigue Stress

Fatigue. 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.sp.info Fatigue Properties and Endurance Limits of Stainless Steel ...Fatigue limit Stainless steel exhibit a 'fatigue limit' or 'endurance limit' during cyclic stressing. This means that there is a stress level, below which fatigue failure should not occur. This is determined from a series of fatigue tests, run to failure at various stress levels. The fatigue stress limit is reached when failure does not occur after a million (106) or 10 million (107) cycles.sp.info Fatigue limit - WikipediaThe Fatigue limit also known as the endurance limit or fatigue strength is the stress level below which an infinite number of loading cycles can be applied to a material without causing fatigue failure. Ferrous alloys and titanium alloys have a distinct limit.sp.info ASTM A36 (SS400, S275) Structural Carbon Steel ...ASTM A36 (SS400, S275) Structural Carbon Steel. ASTM A36 carbon steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. It has a very high electrical conductivity among the wrought carbon or non-alloy steels in the database.
