Stress Free Head Hardened Rail

Excellent wear-resistance and uniquely low residual stress for reduced foot fatigue are the hallmarks of our Stress-Free heat-treated SF range.

Designed for use on curved and heavy haul tracks, it is available to EN, AREMA and other national and international standards.

Our uniquely low residual stress rail is produced using a unique patented heat treatment process that ensures exceptional wear resistance, ensuring our SF rail provides longer service lifetimes.

The low residual stresses achieved substantially reduce the risk of rail foot fatigue failure compared to all other heat-treated rails.
