Not necessarily. I’d venture that the bits may be hardened, but the rods would be too brittle. |

Drill Here, Drill Now

| It's not my end of the business. BBS is likely the most knowledgeable Sigforumite in this. I do know enough to know that there are dozens of possibilities and some are very exotic alloys. Are there any markings on it?

| I sold directional boring rigs which are a similar industry. Typically drill rods are made 2 different ways. They are either forged and then the ends hardened or a hardened steel (like 4140) is inertia welded to the end of the tube. Either way, the end of the rod where the threads are is hardened. I guess I didn't know much about carbon content back then but I'd say the inertia welded rod end will certainly have a higher carbon content. If in fact this is a well drilling rod and not a directional drilling rod, it's likely a forged piece.

| Added information, should have included earlier - rod is SOLID, not a tube, near the ends are flats, making a square cross section for large wrenches to unscrew the sections from one another. I believe the threaded areas are tapered threads, but not certain.
While the steel may be of a higher carbon content, or an alloy (which is what I am trying to figure out), it is not currently hard. Pieces have been cut off with a metal cutting bandsaw.
A full length section is pretty close to 16’ long.
Might try the TIG idea, as that information would be more that I already have.
Have not yet checked the threaded section for hardness, will do that today. I would be inclined to think the rod is forged as well.
No markings whatsoever. 100% surface rust.
In this case it appears that two sections were screwed together on a job and they couldn’t get them unscrewed. They cut them apart with a torch, then scrapped them both. I bought the two 16’ pieces at the scrapyard.
Thanks for your thoughts guys - |
