Abstract

Weldable steel rods for use in reinforced concrete, so-called concrete steel, are in the form of a concentric core region and a surface layer. The core region is formed of a pure perlite-ferrite mixed structure, in which the proportion of ferrite is from 20 to 80%. The core region is directly adjacent to the surface layer, without any intermediate layer. The surface layer is composed of pure, annealed martensite. A method for the production of such concrete steel is also disclosed.
