CarTech Extendo-Die hot work die steel combines extreme toughness with good red hardness in large section sizes.

While CarTech Extendo-Die hot work die steel has been used primarily as a hot work tool steel, it may also be considered for many cold work applications where H13 is currently being used, particularly in large section size applications.

CarTech Extendo-Die hot work die steel can be water cooled in service.

Applications:
CarTech Extendo-Die hot work die steel has been used for hot working tools which require the greatest possible toughness in large section sizes.

Typical applications have included dies and mandrels for aluminum extrusion tooling as well as dies and inserts for aluminum die casting.

Hot work tools made from CarTech Extendo-Die hot work die steel should be considered for cold/warm work applications where extreme toughness is required in large sections.
