HSH® Grooved Rail Steel R340GHT

The rail steel grade R340GHT according to EN14811:2019 is a fine pearlitic rail grade. It is produced by the application of the HSH® heat treatment technology. This rail steel has been designed for customers following a “put-in-&-forget” strategy, meaning that gauge corner repair welding is not necessary to reach extended service lives in curves

Application area

Due to its high wear resistance, this rail steel has evolved to a popular solution for curves with radii below 150 m. It is used by customers, who prefer the “put-in-&-forget” strategy where gauge corner repair welding is not necessary.


Because of its high resistance against side- and head wear, rail steel R340GHT to a significantly prolonged rail service life.
