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.
