Hot work tool steel is the "core tool" of the metal forming industry, directly determining the service life, forming precision, and production efficiency of dies. Operating in a unique environment, it must maintain structural stability and reliable performance under repeated heating-cooling cycles at 500–1000°C, making it an indispensable basic material for high-end manufacturing (automotive, aerospace, etc.).
Core Features
High-temperature resistance: Maintains sufficient strength at 500–1000°C to prevent softening and deformation.
Thermal fatigue resistance: Resists thermal cracking under repeated heating-cooling cycles.
Toughness-strength balance: Combines high strength with good toughness to withstand impact loads during operation.
Wear and oxidation resistance: Forms a stable oxide film on the surface, reducing high-temperature wear and oxidative corrosion.Typical application areas
Automotive manufacturing: Die-casting dies for engine blocks/cylinder heads, hot forging dies for crankshafts/connecting rods, hot stamping dies for high-strength steel.
Aerospace: Precision forging dies for blades, hot extrusion dies for spacecraft structural components.
Non-ferrous metal processing: Die-casting dies for aluminum/copper/zinc alloys, profile extrusion dies.
Machinery manufacturing: Hot forging dies for gears and shaft parts, hot forming dies for hardware tools.
