- Mould and Dies, for instance:
– Plastic injection molds for corrosive resin containing high glass-fibre content
– IC mold parts - Other applications like:
– Injection components
– Custom Hand knives and Machine knives
– Valves, Actuators and Bearings
– Structure parts
- Very high wear resistance with high hardness
- Good toughness and ductility
- Good machinability
- Good dimensional stability
- Good corrosion resistance
