Steel properties
Excellent wear resistance and toughness at high temperatures. Good machinability in annealed condition. Good polishing. Good hardenability. Very good dimensional stability. Excellent tempering resistance.
 
Applications
Dies, tools for the production of screws and forging machines highly stressed extruding tools for light metal processing - mandrels, pressing die cast moulds. For the highest requirements we recommend UTOP33 ESR EFS.
