INVESTIGATION OF 140 LB/YD RAIL MADE FROM VACUUM DEGASSED STEEL

The purpose of this investigation is to determine whether rails made from vacuum degassed steel, which is air cooled, are comparable in properties with rail steel produced by currently common practices using controlled cooling. The manufacturing process and test specimens are described. Rolling-load tests, drop tests, slow bend tests, hardness surveys, Charpy Impact tests, chemical analysis, and microscopic examinations were performed. Results and conclusions show that the properties of rails manufactured by vacuum degassed heat without controlled cooling were comparable to rails made by conventional techniques and subjected to controlled cooling.
