The rail steel 290GHT-CL is an advancement of the rail steel R290GHT and is characterized by an extra low carbon content of max. 0.5 %. Gauge Corner Repair Welding of this rail steel is provably possible with the same welding parameters as for grade R200.
By the heat treatment, this rail steel experiences a significant improvement in wear resistance and is thus ideally suitable for the use in curves of operators, who prefer easiest gauge corner repair welding.
The special material concept allows easiest gauge corner repair welding with parameters of grade R200. The increased wear resistance prolongs the first repair welding cycle and leads to a longer overall rail service life in curves.
