H13 tool steel offers High hardenability, excellent wear resistance and hot toughness, has been widely used in hot forging dies, pressure dies casting tools, extrusion tools, hot shear blades, stamping dies, plastic mold and aluminum alloy die casting dies.
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.
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.
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.
Quick-turn prototyping and short production runs for all industries.
