H11

H11 steel combines high hardness and toughness, and exhibits outstanding performance under extreme working conditions. H11 steel has excellent hardenability and can be hardened by air cooling, greatly reducing the risk of mold heat treatment deformation and cracking; H11 steel has stable thermal strength and oxidation resistance under medium temperature environment, and can maintain good mechanical properties within 600 ℃. It has strong resistance to cold and hot fatigue, and is not easy to crack under frequent cold and hot cycles. H11 steel has excellent resistance to low melting point alloys such as aluminum and magnesium.

As an air-cooled hardening type hot work die steel, H11 steel has excellent high-temperature strength and toughness. Its chromium molybdenum vanadium alloy system endows it with excellent heat fatigue resistance and wear resistance. H11 steel maintains high hardness under 500-600 ℃ working conditions, while also having good cutting and heat treatment stability, making it particularly suitable for the manufacturing of aluminum/magnesium alloy die-casting molds and hot forging dies.

Сталь 4X5MΦC обладает высокой твердостью и ударной вязкостью и подходит для литья под давлением, экструзии, горячего прессования алюминия, меди, магния.
