Hot Die Steel H-12 is a chromium-molybdenum-vanadium alloy tool steel known for its exceptional heat resistance, toughness, and wear resistance under high-temperature conditions. It is commonly used in hot-working applications such as die-casting, forging, and extrusion, where the material must withstand severe thermal stresses and cyclic heating and cooling. The steel’s composition ensures high hardenability, thermal fatigue resistance, and strength at elevated temperatures, making it ideal for tooling that is exposed to extreme heat during manufacturing processes. H-12 steel is designed to offer high thermal conductivity, which allows it to distribute heat more efficiently, reducing the risk of heat-related cracks or failures. It also maintains its mechanical properties even after prolonged exposure to high temperatures, ensuring a longer service life for tools and dies. This steel can be heat-treated to achieve a balance of hardness, toughness, and thermal stability, ensuring that tools made from H-12 remain reliable and durable in harsh, high-temperature working environments. It is widely used in industries like automotive, aerospace, and die manufacturing.
