Steel carabiners are more ductile, thus allowing a greater amount of energy to be absorbed by the carabiner prior to failure. The ductility also helps the carabiner be more resistant to misuse such as non-straight line loading. Steel carabiners are inherently more resistant to corrosion in alkaline environments.
