![]() (They may be scaley and/or have surface rust). These railroad spikes feature a forge or mill finish as they leave the mill. Thus, the result is railroad spikes that 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 railway spike with the higher strength of the high-carbon spike and the impact resistance and ductility of the low-carbon spike. Both of these elements increase the strength of the material. The carbon for these forging railroad spikes ranges from 0.17 to 0.25%C with a manganese content of 0.90-1.35%Mn. The revised specification was designed to “bridge” the gap between the older low and high-carbon grades. The new "high-carbon" railroad spikes have an average content of about 0.22%C. ![]() The older “low-carbon” spikes specified featured a content of around 0.13%C. In the past, there were two distinct grades of railway track spikes, “low-carbon (LC)” and “high-carbon (HC)”. Forge finish with mill scale - no coating.Railroad Spike Viking Scramasax Knife, AOC Exclusive Viking Seaxe Knife. Try these railroad spikes when forging your first knife, hatchet, tomahawk, letter opener, bottle opener, etc. The 3 Best Viking Museums in Scandinavia. Sockets & Drivers for Square head Bolts.Refflinghaus Professional Anvils (Germany).If you would like to show off your spike knives or anything else made with a spike check out this Facebook group, that is if you tolerate Facebook. If you want the head then either forge the head manually or make a swage block, best part is you can use a swage block to shape any tool steel into a spike and have a functional knife in the end that looks like a spike. You can buy bar stock from any steel supplier in the AISI 1040 or 1045 category and have a steel that will work easier without having to deal with rusty spikes. Imagine being at work and having several people walk in each day looking for free stuff and you can see they might be less than friendly. Visiting the rail yard and talking with the crews is better but you have to also consider how many people go wandering through the yard every week looking for free steel. One word of caution though is that walking the tracks can be hazardous to your health and is considered trespassing so if you get arrested and charged don't be shocked. ![]() fact is like any mild steel they can be shaped into anything you heart desires. Things I have seen to date range from knives, forks, flowers and coat hooks. This is the final step before polishing our newly made knife. Now the good parts? If you are given a few hundred pounds of spikes and want to make something with them then go for it. In this lesson, we put on the finish grind and patina. It simply shows that pretty much any steel can be used if prepared properly. To get it out of the way right off the bat:ġ) not a high carbon steel, the HC simply designates a spike with higher carbon than a conventional spike.Ģ) no magical properties, HC spikes have on average 0.33% carbon and minor alloys.ģ) holding a rail in position does not require super strong steel or even super duper strong.Ĥ) Paper can cut you that does not make it the ultimate material for knife making.ĥ) passing the blade smith test with a spike knife is not testament to the high quality of railroad spikes.
