Hardening
Effective and efficient
In modern industry, materials must withstand increasingly high loads. 
hardening processes are therefore essential for making components more durable and long-lasting. They improve the strength and wear resistance of materials and are indispensable for modern manufacturing processes.
Particularly at process temperatures ranging from 800 to 1,000 °C in vacuum or oxygen-free inert gas atmospheres (e.g., argon, nitrogen, helium), they enable precise material properties and a high degree of process control.

Applications
Hardening processes are used in numerous industries, including:
- Energy: Components for Turbines and Wind Turbines
- Chemistry: Components for Corrosive Environments and High-Pressure Processes
- Automotive: Transmission gears, shafts, and structural components subject to wear
- Aerospace: Mechanical Components for Landing Gear and Landing Flaps
Features
The characteristic properties of the material define its functions:
- Graphite: High thermal conductivity, chemical resistance, low thermal expansion, electrical resistance
- Soft and hard felts: Excellent insulating properties; flexible or dimensionally stable, depending on the type
- CFC: Lightweight, high mechanical strength, resistant to thermal shock, dimensionally stable even with temperature fluctuations
Applications
Components made of graphite, soft and hard felts, and CFC (carbon fiber-reinforced carbon) play key roles in hardening processes:
- Thermal insulation made of soft and hard felts reduces heat loss and ensures consistent temperatures throughout the process.
- hard felt sheets provide stability at high temperatures and protect against thermal stress.
- CFC loading racks serve as lightweight, dimensionally stable supports that reliably maintain their shape even under extreme conditions.
- Gas flow elements Graphite optimizes quenching in high-pressure gas quenching processes.
- Heating elements Graphite or CFC offer a uniform heat input
