Ductile refers to a more malleable steel which allows for the hook to bend and not snap off when reaching limit....
The purpose of the recovery hook is to provide a safe and secure point from which to
recover a stuck vehicle. The hook should be strong enough to enable the recovery
of a stuck vehicle, but more importantly must be designed so that if recovery forces
exceed the design forces, it fails in a safe manner. To do so the hook must bend
and release the rope. If the hook fails by breaking, the loose metal becomes a
potentially lethal missile.
