Summary:A b s t r a c t Frog, in particular frog point, for rail crossings or rail switches as well as process for producing same In a steel frog for rail crossings and rail switches, the frog point or, respectively, the surface of the frog being travelled upon by the wheels consists of an agehardening steel having the composition C 0.01 to 0005 % Ti 0.1 to 1 % Si 0.01 to 0.2 % Cr 0 to 13 % Mn 0.01 to 0.2 % Al 0 to 0.2 % Co 0 to 15 % B 0 to 0.1 % Mo 1.5 to 6 % Zr 0 to 001 % Ni 7 to 20 % The frog is manufactured such that the surface being travelled upon by the wheels is applied by build-up welding onto a base body consisting of nominal rail steel.
