Do you know the difference between the low carbon track spikes and high carbon ones?
“Low carbon (LC)” and “high carbon (HC)”were two distinct grades of track spikes in the past.
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 railroad 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 railroad spikes have the advantage of improved impact resistance and improved ductility, while maintaining a relatively high strength.
We are able to supply railroad track spikes with various sizes that are provided to meet the different requirements of penetrating length of spikes. For smaller rail sections, the 5/8"*6"and the 9/16"*5-1/2" are the most two common types of dog spikes, and they are usually packaged in either 200 lb. kegs or 50 lb. kegs.
