Description
'J 'ht' c· f feet of seawater ,_tnd potential on the fatigue crack
initiation hehavior of several microalloyed and thermomPrhanically
processed steels has been investigated. Five
steels with yield strength in t~e range 500 to 750 MPa (73
to 108 ksi) were selected which included a range of processing
histories from conventional quenching and tempering to
precipitation hardening and direct quenching. These steels
were chosen because of their potential utility as materials
of construction for deep water compliant platform hull and
riser systems. Blunt notch compact tension specimens were
exposed to natural flowing seawater under constant load ampli
tnrlc. conditions at both freely corroding and cathodically
protected potentials. Cycles to crack initiation were
characterized by cyclic stress intensity range normalized
relative to the square root of notch radius. Test data are
presented and compared with data from other tests and steels
using appropriate stress analysis methods.
