摘要
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 age-hardening steel having the composition -C 0.01 to 0.05% 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 0.1% -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.
