This paper presents work in follow-up to the previous study. It is focused on UNS1 N07718, UNS N09925, UNS N07725 and UNS N09946. A series of incremental step load tests of compact tensile specimens were conducted to measure the fracture toughness during testing and cracking was monitored by the Electric Crack Growth Monitoring technique. A new engineering technique, referred to as statistical fractography, was used to investigate the fracture surface morphology and extract from it the fracture properties of the alloys.

Failure Analysis On A Carbon Steel Pulsation Dampener In Glycol Service Using Statistical Fractography Highlights A Stress Corrosion Cracking Contribution

A cold-worked carbon steel pulsation dampener located on a glycol circulation pump failed catastrophically in service. The two parts of the failed dampener were projected several tens of meters across the offshore facility. The failure was investigated initially using traditional metallurgical techniques, but this failed to reach a conclusive failure mechanism.
