Steel FSR:
temper resistance and wear resistance .

FSR  steel is a cold work tool steel based on 12% Cr. The other alloy elements give FSR the necessary temper resistance and wear resistance.

Compared to a similarly used high-speed steel such as type HS6-5-2C, FSR is characterised by better toughness with equivalent performance.

  • Better toughness.
  • Wear resistance.
  • Cutting tools with particular wear resistance in the processing of siliconised or austenitic sheet metal or hardened strip steel, precision punching tools.
  • Cold extrusion tools.
  • Threaded rolling tools.
  • Broaches.
  • Extruder screws.
