Abstract
Diagnosis of environmentally induced failures is greatly facilitated by metallographic analysis. As an example, a failure analysis of ASTM A574 material grade bolts is presented. The bolts served as bonnet screws in underground valves and failed due to stress-corrosion cracking. Metallographic methods were used to diagnose and provide solutions for the service failure. Included are photos showing crack propagation morphology and fracture surface appearance.
