Handbook of Case Histories in Failure Analysis
Failure of a Stud From a Boiler Manhole
A stud that was part of a man hole cover on an old steam boiler broke when it was dropped. The boiler was more than 100 years old, but still performed satisfactorily when fired up at regular intervals. Chemical analysis showed the steel to be a low-carbon EN2 type. Microstructural examination indicated brittle fracture caused by strain aging. Replacement of all studs on the man hole cover and examination of the boiler steel in other places were recommended.
