Technical Characteristics
The mechanical properties of SD Reinforcing Steel are achieved with the use of the suitable chemical composition and special heat treatment (see Figure) during production. The chemical composition is characterized by the increased content of the elements that give steel its “natural hardness”.

With the special heat treatment, the surface of the steel is submitted to hardening, which gives steel high strength, while its interior part is cooled less intensely, giving it high ductility.
