Applications
- Cutting tools such as chisels, milling cutters, drill bits, reamers, thread taps, and dies.
- Cold work tools such as dies, molds, cutting punches, and forming punches.
- Precision tools.
Characteristics:
- High-speed steel with high tungsten and molybdenum content.
- Good cutting ability at high speeds, retains hardness at elevated temperatures due to its red hardness resistance.
- Excellent hardness with high wear and abrasion resistance.
- Good toughness with resistance to moderate mechanical stresses.
- Good hardenability.
