A technique includes providing a tool to be deployed in a well to perform a downhole function. The downhole function requires a minimum structural integrity for an element of the tool. The technique includes forming at least part of the element from a ferrous alloy and charging the alloy with hydrogen cause the element to be more prone to cracking than before the hydrogen charging.
