H10 Tool Steel

H10 Steel is a type of hot-work tool steel that is specially designed for applications where tools and dies operate at very high temperatures and heavy pressure. It belongs to the chromium-molybdenum tool steel family and is known for its excellent heat resistance, high strength, and good toughness. H10 steel can maintain its hardness and mechanical properties even when exposed to repeated heating and cooling cycles, which makes it highly reliable for hot-working processes.

H10 steel typically contains alloying elements such as carbon, chromium, molybdenum, silicon, and vanadium, which improve its wear resistance, thermal stability, and durability. After proper heat treatment, it can achieve a hardness of around 50–52 HRC, allowing it to perform well in demanding industrial environments. Because of its ability to resist thermal fatigue and cracking, H10 steel is widely used in manufacturing hot forging dies, die-casting molds, extrusion dies, punches, and other high-temperature tooling components. It is commonly used in industries such as automotive, aerospace, and metal forming, where strong and heat-resistant tool materials are required.
