ESDU 83002 provides a graphical presentation of the allowable stresses in both compression and tension springs for static or fatigue loading of common spring materials. Data are given for 6 carbon steels@ 4 alloy steels@ 6 stainless steels@ 3 titanium alloys@ beryllium@ copper and phosphor bronze to British@ U.S. and German standards. The influence on fatigue life of spring geometry@ elevated temperature@ corrosive environments and surface finish are discussed and treatments that improve fatigue life such as prestressing@ shot peening@ abrasive cleaning and low temperature heat treatment are examined. A procedure for estimating a complete stress versus endurance curve (S-N curve) from available static and fatigue data is outlined. The materials are tabulated for easy reference and an example of how the graphs are used is also included.
