We have performed thousands of failure analyses. Below is one of many examples from our failure analysis laboratory menu.

Saddle Spall Failure Investigation - by Touchstone Research Laboratory

A company with a Ni-hard cast iron roll had a large saddle spall failure, and Touchstone failure analysis experts were called in to determine the cause.

Evaluation of the fracture found that one side of the spall had been heated more than the other. This was indicated by the depth of firecracks.

This knowledge and observation prompted a review of rolling records. It was learned that a mill wreck had occurred just prior to the roll failure and that no examination of the mill rolls had been performed.

That led to the determination that the cause of the failure was overheating from long contact with the strip after the mill wreck.
