General remarks:

  • AISI C1095 (DIN 1.1274) is a brittle high carbon steel with high hardness and great strength
  • Contains 0.9 – 1.03 wt% Carbon, can contain traces of Cr, Si or Mo as non-alloy elements
  • Magnetic, hardened carbon steel
  • Can be hardened by induction heating and quenching
  • Properties can be varied by different heat treatments
  • Can be used wear corrosion is not an issue
  • Generally used where high strength and hardness for cutting tools are required
  • Typical applications include cutting blades, knifes, flat spring, scraper blades and mower blades
