According to ASME B30.9 – Slings, any wire rope sling with a kink must be removed from service.
A kink is a type of damage that distorts the rope’s internal structure. Even if the deformation appears minor, the integrity of the sling has been compromised.
This kind of damage is irreversible and weakens the sling in a way that is not visually predictable. Continued use leads to metal fatigue and increases the risk of sudden failure—similar to bending a paperclip until it snaps.
Refer to ASME B30.9-2021, Section 9-5.9.5(b)(8) for full removal criteria.

It’s actually cold working the metal, not fatigue. In cold working the dislocations (impurities) are actively traveling through the metal during the plastic deformations and collecting together. This leads to failure of the material in single digit or tens of cycles, where fatigue failure results from 10,000s to 100,000s of cycles. This is exactly why you are right to stop use of any wire rope with plastic deformation, ie kinks. The same goes for any other metal safety equipment or life threatening if broken thing.
