Material Notes:

Data provided by Carpenter Technology Corporation.This steel combines extreme toughness with good red hardness in large section sizes. This alloy may also be considered for many cold work applications where H13 is currently used, particularly in large section size applications. Extendo-Die® hot work die steel can be water cooled in service.Extendo-Die® is a registered trademark of Carpenter Technology Corporation.
