Uddeholm Unimax®

Uddeholm Unimax is a high hardness hot work tool steel which provides great wear resistance even over extended time at elevated temperatures. It performs very well in precision forging and hot stamping.

• Improved durability and wear resistance in molding processes that wear hard on the mold like, long run production, molding of reinforced plastics and compression molding
• Longer tool life and a smoother production run with fewer disturbances for maintenance due to the high ductility
• 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 molds. Unimax is therefore supplied in larger dimensions
