Hot-work die Steel H13


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.

Advantages

For high-quality tool steel, steel mills generally adopt the smelting processes such as furnace refining, vacuum treatment, vacuum smelting, powder spraying and electro slag re-melting to reduce the content of harmful elements such as oxygen, hydrogen and inclusions in steel.

Disadvantages

Poor density and low purity;
Severe annealing banding segregation and uneven annealing structure;
After quenching and tempering, many liquid carbides remained unchanged; In the impact test, the place where the chain-like liquid carbide accumulates is easy to crack, and the fracture is characterized by horizontal streaks and low toughness.

Industry application recommendation

Inserts, cores, and cavities for die casting dies, die casting shot sleeves, hot forging dies, extrusion dies, and plastic mold cavities and components that require high toughness and excellent polishability.
