The rail steel R290GHT according to EN 14811:2019 is a fine pearlitic, heat treated rail grade with a minimum hardness of 290 HB. This steel grade offers the perfect balance between wear resistance and gauge corner repair weldability.
This rail steel grade is recommended in curves for customers following an “easy to maintain” strategy.
The low Carbon content of the grade R290GHT assures easy and process-reliable gauge corner repair welding. The increased wear resistance prolongs the first repair welding cycle and leads to a longer overall rail service life in curves.
