Applications
- Molds and their parts for the plastic industry.
- Components of medical and surgical equipment.
- Pump components.
- Machinery parts with corrosion resistance in moderate environments.
- High-durability kitchen utensils and cookware.
- Valve seats and pistons.
Characteristics:
- Steel capable of hardening by heat treatment, which improves hardness, wear resistance, and toughness.
- Good corrosion resistance in moderate environments.
- Martensitic structure, which makes it magnetizable.
- Good machinability, superior to other stainless steels.
- Limited weldability, requires preheating and post-treatment.
- Higher mechanical strength compared to austenitic stainless steels.
