Steel HS1
HS1 steel:
resistant to wear, compression strength and toughness.
What?
HS1 steel is hot work tool steel with high resistance to wear and high compression strength with balanced toughness. Suitable for secondary hardening and for use at high temperatures. Nitriding and coating possible.
Material properties
- Wear.
- Compression strength.
- Toughness.
Application
- Shear blades
- Cutting and punching tools
- Bending tools
- Pressing and profile rollers
- Segments for press tools
