Unimax
Unimax is a chromium-molybdenium-vanadium alloyed universal tool steel with an excellent combination of high ductility and high hardness. The exceptional properties offered, enables it to be used in many tooling applications to improve the tool life and productivity.
The exceptional combination of high ductility and high hardness makes Unimax a problem solver in cold work applications such as heavy duty blanking, cold forging, and thread rolling where high chipping resistance is required. Unimax is also perfect when moulding big and complex parts or where the plastic details wear hard on the mould. Actually the bigger mould and the more complex details and moulding conditions the greater is the improvement of the total economy.
Benefits:
Improved durability and wear resistance in moulding processes that wear hard on the mould like, long run production, moulding of reinforced plastics and compression moulding
Reduced cycle time and improved productivity due to the superior heat diffusion properties
Longer tool life and a smoother production run with fewer disturbances for maintenance due to the high ductility
Problem solver in severe cold work applications where high chipping resistance is required
The high hardness and toughness together with the good dimension stability makes Unimax suitable as a substrate steel for surface coating when needed
The very good hardenability and the unique properties profile of Unimax make it especially suitable for larger moulds. Unimax is therefore supplied in larger dimensions
Properties:
- Excellent toughness and ductility in all directions
- Good wear resistance
