The research results of the effect of small additions of vanadium and nitrogen on the microstructure and mechanical and service properties of high-carbon steels for railway transport are presented. The data on industrial production of metal products from such steels are considered. Medium-carbon bainitic and martensitic steels with a fine structure microalloyed with vanadium and nitrogen have a unique set of properties: a combination of high values of strength, ductility, cold resistance, and endurance under fatigue loading, which will increase the resistance of rails during operation not only at low temperatures, but also under conditions of increased loads, in curves of a small radius and in the event of a risk of thermomechanical damage.

钒氮微合金化运输钢

介绍了微量钒和氮添加量对铁路运输用高碳钢组织、力学性能和使用性能影响的研究结果。考虑了这些钢的金属产品的工业生产数据。具有微合金化钒和氮的精细结构的中碳贝氏体和马氏体钢具有一组独特的性能：结合了高强度、延展性、耐寒性和疲劳载荷下的耐久性，这将增加钢轨在使用过程中的阻力。不仅在低温下运行，而且在负载增加、小半径曲线和热机械损坏风险的情况下运行。
