▶ Rolls for cold straightening 

▶ Heat treatment:

  • Uniform barrel hardness 

  • Hardening depths up to a barrel radius of 14-30 millimetres

  • Excellent wear resistance

  • Optimised residual stress levels

▶ Mechanical production:

  • Greatest dimensional accuracy

  • Greatest concentricity

  • Required hardness specification through specific selection of materials and additional heat treatments
