Thus, the resultant railroad spikes have the advantage of improved impact resistance and improved ductility, while maintaining a relatively high strength. This specification has a minimum yield strength requirement of 46,000 psi high for a low to medium carbon product. The goal was to provide a railroad spike with the higher strength of the high carbon spike and the impact resistance and ductility of the low carbon spike. As such, theyre indispensable for railroad transportation. Both of these elements increase the strength of the material. Railroad spikes have been actively used to secure rails to lateral support since the 1930s. The carbon range for these track spikes is from 0.17 to 0.25%C, and the manganese content is 0.90-1.35%Mn. The revised specification was designed to “bridge” the gap between the older low and high carbon grades. The new track spikes have an average content of about 0.22%C. The older “low carbon” spikes specified and very low carbon content of around 0.13%C. In the past there were two distinct grades of track spikes, “low carbon (LC)” and “high carbon (HC)”. forge finish with mill scale - no coating.We only use new, high caliber railroad spikes and our.
