| Abstract: | A new 50CrVE steel is developed for the side-rolling resistant torsion bar used in railcars, and relevant testing is also carried out. The testing results indicate that the new material is characterized by an even structure, Jess non-metallic inclusions, excellent hardenability, and is completely up to the level of international quality steel. The side-rolling resistant torsion bar made of this steel exhibits high fatigue life span and elastic limit. |
