... at a large automotive part manufacturing facility. The incident resulted in no personal injury. Results of the failure analysis show that the inner diameter (ID) of the tank displays a macroscopic web-like network of cracks that deceptively suggests intergranular stress corrosion cracking (IGSCC). Low...
