Abstract
To manufacture frogs or rail sections in the wheel-running region of points with a highly wear-resistant wheel-running surface of a hardenable steel of composition C 0.01 to 0.05 % Si 0.01 to 0.2 % Mn 0.01 to 0.2 % Co 0 to 15 % Mo 1.5 to 6 % Ni 7 to 20 % Ti 0.1 to 1 % Cr O to 13 % Al 0 to 0.2 % B 0 to 0.1 % Zr 0 to 0.1 % the wheel-running surface is applied by explosive plating or electron beam welding or compound-rolling to a base body of readily weldable steel, especially a steel having not more than 0.24 % of C, not more than 0.04 % of P and S, not more than 0.65 % of Si and not more than 1.7 % of Mn.
