General Information

Ovako 280T is our premium variant used in the hollow bar program of Ovako. Ovako 280T meet and is exceeding the demands of E470 in     EN10294-1. Ovako 280T is a micro alloyed steel with high tensile strength, good machinability and weldability. 

  • Suitable for case carburizing or nitriding
  • Good dimensional stability
  • Fine-grain treated
  • Delivered in as-rolled, normalized or quenched and tempered condition
  • Weldable if preheated

Ovako 281T is a micro alloyed steel that is suitable for quench and tempering and possess a high tensile strength. 

Ovako 281P is an additional variant of 281, which possess slightly different mechanical properties.
