Hot work tools operate at elevated temperatures and form different products in e.g. aluminium, steel or other metals. The most common application areas in hot work are die casting, extrusion and forging. The high working temperatures put very high demands on the tool steel. Material for hot work applications should have a properties profile like a very good hot strength as well as a very good ductility and toughness. Other important tool steel properties are a good resistance against thermal cyclic stresses and a good hot wear resistance. The properties profile should be even in all directions in the tool steel for best performance.
