FDAC is a high-quality hot work tool steel designed specifically for applications that involve extreme thermal and mechanical stress, such as die casting and forging. It is known for its excellent machinability in its pre-hardened state and does not require further heat treatment, making it convenient for immediate use in tooling applications. FDAC combines good toughness, high wear resistance, and the ability to withstand repeated heating and cooling cycles without losing its properties.
Key Characteristics:
Composition: Typically contains chromium, molybdenum, and vanadium, which contribute to its hardness, wear resistance, and thermal stability.
Hardness: Pre-hardened to around 30-34 HRC, eliminating the need for additional heat treatment and simplifying the tooling process.
Heat Resistance: Good resistance to thermal fatigue, suitable for high-temperature environments like die casting and hot forging.
Toughness: Excellent toughness and resistance to cracking under high thermal stress.
Machinability: Superior machinability due to its pre-hardened condition, allowing for easy and precise machining.
Common Applications:
Die casting molds for aluminum and zinc alloys
Hot forging dies and punches
Extrusion tools for metals
Plastic molding dies that require high thermal resistance
Components in high-stress, high-temperature applications
FDAC hot work tool steel is widely used in tooling applications where high performance and reliability are essential. Its pre-hardened state makes it particularly attractive for reducing manufacturing time and costs, while its strong combination of heat resistance, toughness, and wear resistance ensures long tool life and consistent quality in hot work operations.
