Where an optimum balance of high wear resistance and excellent rolling contact fatigue resistance is needed, our High-Performance rail HP335 is the perfect choice.
This non-heat-treated rail is designed for curved track and other high duty areas, where it is proven to improve wear resistance, cut life cycle costs, reduce grinding frequency and extend rail life.
HP335 is a microstructurally engineered rail with a uniform through-hardness that provides the best performance and lower life cycle cost for mixed traffic networks.
Suited to a wide range of applications, HP335 (also known as HPrail®) was approved for use by Network Rail in 2012 and is the premium rail of choice in the UK mainline network. Several light rail operators have also adopted HP335 as their premium rail solution for reducing wear, corrugation and grinding requirements to maximise rail life whilst reducing life cycle costs.
Our HP335 has been independently verified to deliver lower wear rates than R350HT rails without the need for heat treatment. It also delivers greatly improved rolling contact fatigue (RCF) performance above other 'as-rolled' rails. This reduces the need for rail grinding to control RCF by typically 66%, increasing rail life, improving track availability and reducing maintenance costs.
The high performance of HP335 rail means reduced life cycle costs for infrastructure owners/operators. Savings of more than 60% have been independently quantified where HP335 has been used as a replacement for R260.
HP grades have been extensively proven for more than a decade in varied applications from light-rail to heavy-haul. If you'd like to find out more then please contact us.
