H13 Steel Introduce
What is H13 Tool Steel?
H13 Tool Steel is a versatile chromium-molybdenum hot work steel that is widely used in hot work and cold work tooling applications. The hot hardness (hot strength) of H13 resists thermal fatigue cracking which occurs as a result of cyclic heating and cooling cycles in hot work tooling applications. Because of its excellent combination of high toughness and resistance to thermal fatigue cracking (also known as heat checking) H13 is used for more hot work tooling applications than any other tool steel.
What Is H13 Tool Steel Used For?
H13 is widely used for aluminum and zinc casting dies, as well as for aluminum extrusion, aluminum die casting and press tooling. This grade is ideal for a range of hot work and cold work applications—particularly hot work applications where drastic cooling is required throughout its operation. In addition, H13 is abundantly used in hot work applications where high red hardness and resistance to cracking is vital.
How Do You Temper H13 Tool Steel?
For hot work applications, it is suggested to temper H13 at a minimum of 50 degrees above the expected maximum operating temperature. In instances where heat checking can be an issue, a double temper can be applied—in which the second temper should be 25-50 degrees less than the first.
What is the Hardness of H13 Tool Steel?
Hardness tests determine the various properties of a specific metal, which includes its resistance to wear, toughness, and formability. Two widely used tests are Rockwell C and Brinell. Rockwell C is measured in the unit HRC, which is the measurement used below.

h13 steel wiki
Wikipedia about h13 steel: H13 is a tool steel grade standardised for hot working. The main feature of this grade is the combination of alloyed elements of chromium, molybdenum and vanadium, Cr-Mo-V, which provides a high wear resistance to thermal shock.
