ESDU 84003:2012

ESDU 84003 provides constant amplitude fatigue crack growth rate
data for a wide range of common specifications of high alloy and
stainless steels in the form of plate, sheet, bar, castings or
forgings. The data were derived from results of tests, from many
sources in the literature, made at room temperature in laboratory
air and are presented as curves plotted against stress intensity
factor range down to threshold values for various values of stress
ratio. The chemical composition of the steels and mechanical
properties of the test specimens are tabulated, and summary curves
show the effects of steel composition on crack growth rate and of
stress ratio on threshold stress intensity factor range. Effects of
specimen size, environment, heat treatment, steel composition and
stress ratio are discussed. Practical worked examples illustrate
the use of the data.
