materials and processes for railway applications

DESIGN, MODELLING AND CHARACTERIZATION OF COMPONENTS AND PROCESSES

The railway industry is taking advantage of the ICT-based technology trends that lead toward digitization; the concept of “the digital train” is increasingly being implemented under the influence of Industry 4.0. Nevertheless, trains still circulate over rails and bear substantial similarities between rails and wheelsets from over 100 years ago. Our solid knowledge in metal materials science helps our customers manufacture better, more durable and safer components.

AD-HOC SOLUTIONS

  • Improvement of steel grade, processing and heat treatment of rails, wheels and axles for fulfilling high mechanical requirements.
