No one really questions whether amsteel is strong. It's crazy strong. But it is designed for winch work. For that purpose, it is made with nearly zero stretch. That means the fibers are not going to stretch around a narrow radius. They can bend around it, but with considerable stress on the outside of the curve that eventually can lead to breakage of fibers. This information comes straight from Samson Rope, the amsteel manufacturer. I recommend caution, regular inspection and conservative retirement time.
