Why H13 tool steel Is Widely Used for Aluminium Extrusion Dies
The aluminium extrusion industry demands tooling that can withstand extreme heat, pressure, wear, and continuous production cycles . Choosing the wrong die steel can lead to premature cracking, dimensional loss, downtime, and high replacement costs. That is why H13 tool steel has become the industry’s preferred choice for aluminium extrusion dies. Known for its excellent combination of hot strength, toughness, thermal fatigue resistance, and wear resistance , H13 steel delivers reliable performance in demanding extrusion applications. What is H13 Tool Steel ? H13 tool steel is a chromium-molybdenum-vanadium hot work tool steel designed for high-temperature tooling applications. Equivalent grades include: DIN 1.2344 SKD61 X40CrMoV5-1 H13 is widely used in: Aluminium extrusion dies Die casting dies Forging dies Plastic injection moulds Why Aluminium Extrusion Dies Need Special Tool Steel During extr...
