Heat Treatment Guide & Properties
H13 responds well to controlled heat treatment, developing high hardness with excellent toughness. Double or triple tempering is commonly used to enhance thermal fatigue resistance and tool life in hot work applications.
Annealing
Furnace cool slowly to improve machinability.
Hardening
Air or oil quenching depending on section size.
Tempering
Double tempering recommended for optimum toughness and stability.

■ Chemical Composition
H13 steel is alloyed with Chromium, Molybdenum, and Vanadium to deliver high hot strength and wear resistance. Chromium enhances hardenability and resistance to softening, while Molybdenum improves high-temperature strength and thermal fatigue resistance. Vanadium refines grain structure and improves wear resistance, making H13 suitable for long service life in hot work environments.
■ Mechanical Properties
H13 offers a balanced combination of toughness, hardness, and thermal fatigue resistance. After heat treatment, it maintains strength and dimensional stability under repeated thermal cycles. Its excellent resistance to cracking and deformation makes it ideal for demanding die casting and forging tooling applications.
