H13 ESR Tool Steel – Premium Electro-Slag Remelted (ESR) Hot Work Steel
What is H13 ESR Tool Steel?
H13 ESR is a high-purity, electro-slag remelted (ESR) variant of standard H13 tool steel, offering superior cleanliness, improved toughness, and better isotropic properties. The ESR process refines the steel’s structure, making it the preferred choice for high-performance hot work tooling, die casting, and plastic molds requiring exceptional thermal and mechanical properties.
Key Advantages of H13 ESR Steel
✔ Enhanced Purity & Cleanliness – Reduced non-metallic inclusions for improved performance.
✔ Superior Toughness & Ductility – Greater resistance to cracking and fatigue.
✔ High Heat Resistance – Withstands extreme thermal cycles in hot work applications.
✔ Improved Wear Resistance – Extends tool life and minimizes surface defects.
✔ Better Isotropic Properties – Consistent strength in all directions.
Common Applications of H13 ESR Tool Steel
H13 ESR is widely used in high-performance applications requiring greater toughness, thermal stability, and wear resistance, including:
- Plastic Injection Molds & Blow Molds
- Forging Dies & Extrusion Dies
- Hot Shear Blades & Cutting Tools
- Aerospace and Automotive Tooling
