In the past there were two distinct grades of track spikes, “low carbon (LC)” and “high carbon (HC)”. The older “low carbon” spikes specified and very low carbon content of around 0.13%C.
The new track spikes have an average content of about 0.22%C. The revised specification was designed to “bridge” the gap between the older low and high carbon grades. 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.
Both of these elements increase the strength of the material.
The goal was to provide a spike with the higher strength of the high carbon spike and the impact resistance and ductility of the low carbon spike. This specification has a minimum yield strength requirement of 46,000 psi; high for a low to medium carbon product. Thus, the resultant spikes for sale have the advantage of improved impact resistance and improved ductility, while maintaining a relatively high strength. Buy railroad spikes today!
