Low cycle fatigue data are reported for an ausformed AISI type H-11 steel. Tensile and fatigue properties of the ausformed steel are compared with those of quenched and tempered SAE 1045 steel of comparable hardness.
A small amount of cyclic strain hardening occurs in tension accompanied by a decrease in the strain hardening exponent. This result is unexpected since the initial monotonic strain hardening is only 0.070 which for most metals, indicates that cyclic softening is likely to take place.
Compressive yield strength of the ausformed H-11 is higher than its tensile yield strength and the fatigue resistance of the ausformed H-11 is higher at all lives than that of SAE 1045 steel at a comparable hardness.
