In modern industry, the load limits for materials are constantly being pushed upwards: Gear wheels have to withstand extreme loads, turbine components have to withstand temperatures in excess of 1,000 °C and aircraft components must not warp even in the event of massive temperature fluctuations.
Why hardening is essential
Whether in the automotive industry, aerospace or power generation – wherever components work under extreme conditions, hardening 
is essential.
It makes materials more resistant to wear and ensures a longer service life. Hardening is often carried out under extreme conditions: Temperatures between 800 and 1,000 °C, often in a vacuum or under a protective gas atmosphere such as argon or nitrogen to prevent unwanted chemical reactions.
The challenge is to ensure precise temperature control and reliable process control in this highly sensitive environment – and this is precisely where our material , our expertise and our Graphite People show their best sides.
Graphite: The hidden backbone of hardening processes
Graphite and its carbon-based relatives such as soft and hard felts and carbon fiber-reinforced carbon (CFC) are the real heroes in the background of hardening processes. Their unique material properties make them indispensable components of the systems:
- Graphite heating elements ensure even temperature distribution and thus enable precise processes.
- CFC racks are extremely light and yet retain their shape – even at the highest temperatures.
- Heat-insulating felts prevent energy loss and help to maintain an even temperature distribution in the furnace.
- Graphite gas flow elements control the high-pressure gas quenching and thus optimize the cooling phase, which is crucial for the hardness properties.
The Future is Graphite
The role of graphite will become even more important in the future. Sustainability and energy efficiency are increasingly becoming the focus of industry. Since graphite is not only extremely heat-resistant, but also durable and reusable, it helps to conserve resources and reduce costs.
Without graphite, there would be no modern high-performance hardening processes – and thus no components that meet the requirements of our high-tech world. It is the silent backbone of an indispensable process – invisible to most people, but essential for the industrial future.
