Journal Title: Technika Transportu Szynowego - Year 2018, Vol 287, Issue 3
Abstract
In this article the origin and conditionings of the start of production grooved rails naturally cooled (without heat treatment) in a new steel grade are discussed. Results of mechanical properties, hardness, evaluation of microstructure, fracture toughness and others are presented. Received level of properties is related to the requirements of heat treated rails described in European standard EN14811. Selection of connection technology of rails using arc and thermite weld is also described.
