ESR HSS for Aerospace Machining Applications
The aerospace industry demands extreme precision, high reliability, and advanced material performance in every stage of manufacturing. Whether producing turbine blades, landing gear components, or structural fasteners, machining aerospace-grade metals such as titanium alloys, Inconel, and hardened steels requires cutting tools with superior strength and durability. One material that meets these challenges is ESR HSS – Electro Slag Remelted High Speed Steel.
Key Benefits of ESR HSS in Aerospace Manufacturing
✅ Superior Red Hardness
ESR HSS maintains hardness above 600°C, enabling stable cutting performance at high speeds without losing tool edge strength.
✅ Outstanding Wear Resistance
The refined structure minimizes tool wear when machining abrasive alloys like Titanium Ti6Al4V and heat-resistant superalloys (HRSA).
✅ High Toughness and Stability
Aerospace machining often involves interrupted cuts. ESR HSS resists chipping and breakage much better than conventional HSS.
✅ Excellent Dimensional Accuracy
The uniform microstructure allows for precise tool geometry, essential for aerospace tolerances.
ESR HSS is used to manufacture:
- Aircraft component drills
- Broaches for landing gear materials
- End mills for aluminum and titanium alloys
- Forming dies for sheet metal
- Reamers for high-precision aviation holes
- Gear cutters and broaching tools
As aerospace manufacturers push for higher precision, efficiency, and safety, selecting the right tool material becomes essential. ESR HSS provides a reliable solution for machining aerospace alloys, offering superior toughness, excellent heat resistance, and long tool life. It remains a trusted material for drills, broaches, milling cutters, and forming tools used in the aerospace sector.
