Abstract
Tensioning elements for construction purposes comprising reinforcing rod for prestressing concrete can be fabricated from steel of the following composition: 0.7 to 1.0% by weight Mn 0.7 to 2.2% by weight Cr 0.3 to 0.6% by weight Mo 0.5 to 2.2% by weight Ni up to 0.45% by weight C (preferably at least 0.1% by weight C.) balance iron and unavoidable steel impurities which is subjected to austenitization, oil quenching and optional tempering to a tensile strength of 1400 to 2000 N/mm.sup.2 and an elongation to break in excess of 7% and preferably about 10% and is welded to a terminal element of the same composition but having a tensile strength substantially 10-20% less than that of the rod, and then incorporated into a concrete structure.
