Hot Work Steel enable the hot forming of metals at high temperatures. They possess good strength at elevated temperatures and also resistance to fluctuating thermal loads occurring where the tool surfaces come into contact with materials to be processed. Application: Pressure Die Casting Aluminum & Copper Extrusion Die Forging, Forging Die Blocks Glass Processing, Mandrels Pilger dies for Tube and Pipe manufacture. Properties & Characteristics - High Mechanical Strength - High Polishability - Ductility - High Thermal Conductivity - Good Weldability
