Anthology of rails produced by JSC EVRAZ United West Siberian Metallurgical Plant in the 21st century

JSC EVRAZ United West Siberian Metallurgical Plant is the main manufacturer of rails in the Russian Federation. The work traces the evolution of the plant’s rail assortment over the past quarter century. A brief review of publications on modern concepts of the formation of structural and phase states of defective substructure and properties of volumetrically and differentially hardened pre-eutectoid, trans-eutectoid and bainite rails during production and subsequent long-term operation was performed. The service life of rails is determined by many factors: metal purity, structure, phase composition, operating conditions, heat treatment technology, etc. Special attention is paid to a new type of rail products – rails of the DT400IK category with increased wear resistance and contact endurance made of eutectoid steel, designed for use in difficult conditions. The paper considers the promising areas of rail assortment expansion.
