In Europe the use of high-strength steel for reinforcing bars is increasing and is, to a degree, replacing reinforcement made of mild steel. Both Austria and Sweden have developed reinforcing steel with high yield points (50,000 psi or more), one employing cold working and the other employing "natural" elements, i.e., more carbon and better alloys. This steel increases working stresses and, generally, eliminates the need for end hooks. Failure precautions, crack formation, and deflection considerations limit the full use of this steel.
