The Technology

Xtreme Performance Technology is the sound of the future. Through its systematic development of the thermochemical processing phase, Steeltec is now able to treat almost any conventional standard steel and significantly improve its properties. An ultrafine grain can be imparted to the steel using a carefully controlled combination of heat and mechanical force, producing a steel with properties that could otherwise only be achieved by high alloy concentrations or by complex and costly additional processing stages.

In short: Heat + Force = ultrafine-grained steel technology.png

The Properties

By carefully controlling the production of an ultrafine microstructure within the material, conventional steels can be improved so that they exhibit both high strength and excellent toughness – two properties that normally run counter to one another. The result is an ultrafine-grained steel that comes out on top in any trial of strength.


Properties of steel after XTP® processing:

  • Dynamic strength boosted by at least ten percent
  • Major improvement in material toughness
  • Significantly improved isotropic properties
  • High strength
  • Extremely resistant to crack propagation

The Benefits

Slimmer, lighter, more efficient: XTP®-treated steel gives users access to wholly new high-performance steel solutions for applications where materials have to cope with high levels of dynamic loading or where longer component lives are required.

This provides not only greater design flexibility, but also greater freedom in the engineering and manufacturing processes, as existing components can now be made tougher and stronger or can be downsized without any loss in their ability to transmit forces. Even the most challenging applications in which components have to withstand strong vibrations, high internal pressures or extremely low temperatures can be mastered with XTP® steel. These technologically optimised steels also exhibit notch impact energy values considerably greater than 27 joules even at temperatures as low as -101 °C – temperatures at which conventionally produced standard steels would simply fail.

XTP® treatment also guarantees the highest levels of resistance to crack propagation. For maximum endurance and maximum safety.
