What materials have a tendency to undergo cold work hardening? (Rule 151 stipulates that for heat exchange tubes and tube sheets with such a tendency, flexible expansion methods should be used...)

Clause 151 stipulates that for heat exchange tubes and tube sheets with a tendency to cold work hardening, flexible expansion jointing should be employed. But what materials have a tendency to harden upon cold working? My understanding is that materials prone to cracking are those with a tendency for cold work hardening; please share your thoughts. I also hope experts will kindly share their insights
Cold working hardening is a phenomenon present in most metals, with only differences in their sensitivity to it. This is the standard expression, but it’s not entirely precise.
I think so too; I believe the sentence written by 151 is really of poor quality.
