Historically, premium quality carbon and low alloy head hardened rail has meant that the rolled rail must be straightened before and after heating and quenching to meet railway straightness specifications. One of the main design criterion for Sydney Steel's new head hardening process was to produce a premium alloyed head hardened rail requiring no additional roller straightening after the heating and quenching cycle. This paper describes the steelmaking and heat treating process and outlines the head hardened rail properties with an in-depth evaluation of residual stress in head hardened Sydney steel rail.
