Patented resistance. It is the combination of HSH® heat treatment technology with an innovative materials concept (UHC® concept) that gives this rail steel grade its high resistance. Based on years of experience, the low alloy concept (non-alloy rail steel) also ensures first-rate weldability of this 100 % pearlitic rail steel, standardized as R400HT.
Subways worldwide run smoothly with us. 400 UHC® HSH® is used in underground railways all over the world. The benefits of this rail steel grade particularly come into play under the challenging conditions found in metro systems. Its resistance to wear and to rail damage during operation recommends it especially for use in curves on subway and commuter railways, minimizing the need for maintenance and renewal work.
Low wear. The high wear resistance of the track proves effective against noise and vibrations, with the excellent section stability reducing force in curves and protecting track and vehicles. RCF resistance additionally extends maintenance intervals in the rail network to good effect.
Added value for you:
- Reduction in noise and vibrations due to deferred rail corrugation
- Maximum service life in the track and minimal maintenance costs
- Lowest possible life cycle costs (LCC)
- Available in all sections to EN, AREMA, other standards and customer specifications
- Use in the turnout for continuous optimization of track
- First-rate weldability
- Tightest tolerances and top surface quality
