As a hot-rolled bar with enhanced properties, Special Properties bar by Ovako is not limited to any specific grade and therefore offers increased added value and substantial cost savings due to the SP­Bar treatment‘s effect on mechanical properties.

Special Properties round bars, commonly known as SP-Bars, are the result of Ovako’s continuous product development. SP-Bars are not limited to any specific steel grade, which creates opportunities for customers wishing to use this advanced technology. By optimizing the properties of the bar material, customers can benefit from increased added value and substantial cost savings in manufacturing operations. SP-Bars offer improved mechanical properties compared to regular bars. The result is a longer fatigue life and a greater impact strength.

SP-Bars offer extremely tight tolerances. Consequently, SP-Bars can often replace peeled or drawn bars. Customers can decrease the nominal size and get more manufactured pieces per tonne of purchased SP-Bars.

Scale thickness is generally reduced on SP-Bars. The reduction can be up to 50 percent compared to conventionally hot-rolled products. The reduced scale thickness gives a cleaner environment in subsequent operations such as cold-forming or heat treatment.

Size ranges from 14 to 52 mm and lengths range from 4 to 12 metres.

Advantages of Ovako’s SP-Bars

  • Tighter tolerances that deliver increased yields and repeatability as well as material savings
  • Improved mechanical properties that provide longer fatigue life and greater impact strength
  • Better surface quality that reduces scale and results in cleaner quenching tanks and improved process environment.
