Non-alloy steel 20GL P provides a high-rolling casting with a guaranteed yield strength in the normalized condition > 380 MPa and increased fatigue resistance coefficients of safety of 1.8 to 2.21 for the over-spring beams and 2.0 - to the side frames. The study of mechanical properties of carbon steel St20 hight tempering deformation of strengthening carbonitrid hardening that it has: Tensile strength > 440N/mm2, limit > 330 N/mm2 yield strength, elongation > 35% relative narrowing > 70%, impact strength (KCU) in -70 OC > 60J/sm2. Proposals developed 7 projects for inclusion in the Program Grades cast and deformed high-strength steels for freight cars of the new generation of higher performance.
