FROG FOR SWITCHES AND CROSSINGS
Rolling support and guiding element (2) for a rail vehicle, comprising at least one upper portion forming the rolling surface, said portion being made from steel (1) having a composition comprising, in addition to Fe: −0.15≤C≤0.3%, −1≤Mn≤2%, −0.2%≤Ni≤1%, −0.5≤Cr≤2%, the steel (1) having a mixed structure of tempered martensite and residual austenite and bainite after having undergone a tempering heat treatment at a controlled speed and for a controlled length of time.
