Source:Ref 3 Fatigue data for 4140 steel? - Metal and Metallurgy Jan 19, 2007 · In this specific case, there is a published or test value that was used instead of a default value (like fatigue strength= 0.5 * UTS). Certain metals can exhibit hardening or softening behavior under cyclic loading versus monotonic loading conditions. SAE-AISI 1025 (G10250) Carbon Steel ::MakeItFromSAE-AISI 1025 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1025 is the designation in both the SAE and AISI systems for this material. G10250 is the UNS number. It has a fairly low electrical conductivity among the wrought carbon or non-alloy steels in the database.
SAE-AISI 1045 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1045 is the designation in both the SAE and AISI systems for this material. G10450 is the UNS number. It can have a moderately high tensile strength among the Stress-Life Diagram (S-N Diagram) - UiSThrough many years of experience, empirical relations between fatigue and tensile properties have been developed. Although these relationships are very general, they remain useful for engineers in assessing preliminary fatigue performance. The ratio of the endurance limit S e to the ultimate strength S u of a material is called the fatigue The influence of stress-controlled tensile fatigue loading Residual tensile curves of AISI 1045 steel has been determined after pre-fatigue. At low number of fatigue cycles hardening effect of tensile curve is observed. Close to fatigue strength at high cycle stress material softening may be found. Material softening is
