General
718 Hi Hard is a prehardened mould steel, which offers the following benefits:
Heavier sections are supplied premachined which offers the following advantages compared with un-machined material:
Applications
718 Hi Hard is a prehardened mould steel, which offers the following benefits:
- No hardening risks
- No hardening costs
- Time saving, e.g. no waiting for heat treatment
- Lower tool cost (e.g. no distortion to rectify)
- Modifications easily carried out
- Can be subsequently nitrided to increase surface wear resistance and locally flame hardened to reduce surface damage
- Good polishing and photo-etching properties
- Good machinability
- High purity and good homogeneity
- Uniform hardness
Heavier sections are supplied premachined which offers the following advantages compared with un-machined material:
- Saving of weight
- Non-decarburized surface
- Exact nominal size (plus tolerance)
- Less machining
- Absence of scale minimizes machine and tool wear
Applications
- Injection moulds for thermoplastics
- Extrusion dies for thermoplastics
- Blow moulds
- Forming tools, press-brake dies (possibly flame hardened or nitrided)
- Aluminium die casting prototype dies
- Structural components, shafts
