  • Prestressed concrete

Wire rod for prestressed concrete has high carbon grades (typically over 0.75% C) that can be alloyed with chromium (up to 0.5 % Cr) and vanadium (up to 0.16% V) and is delivered in diameters up to 16 mm.

Depending on the grades and diameters, tensile strength ranges from 1000 MPa to 1350 MPa.

Special know-how is required for prestressed concrete wire rod production and drawing because of the carbon content, alloying elements and the final mechanical properties required.

Key properties

  • Tensile strength related to high carbon content and micro alloying
  • Steel cleanliness
  • Microstructure homogeneity
  • Surface quality
