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
