So I’ve had some long round bars of some steel that I played with about a year ago and performed pretty well with my rudimentary tests. Since then I moved on to only using known steels for, well obvious reasons, and haven’t touched the stuff in a while. It’s a couple different kinds of bars that my grandfather got ages ago when he was working at a sandpaper factory, after I found it buried in his barn I asked him and, he said the bars were rollers of some sort that had to be hard so the sandpaper wouldn’t wear it down so quickly.

Sorry for the backstory I’m sure it is unimportant, but what I’m leading to is I have a bunch of this stuff and I’d like to get it tested to find out the alloy. Hoping I’ll get lucky and it’s something nice. So does anyone know a place where I can send a sample and get an accurate alloy and name put to it? Preferably I don’t want to have to sell my kidneys for it, so if you are aware of the price please let me know!
Sorry if this is the wrong category I wasn’t sure if there was a metallurgy specific section.
Thanks in advance!
 
Companies, and some metallurgists, have devices called X-something. They are hand-held spectroanalyzers. You point it at the metal and it reads the alloys/%. They are like 10K each which is why most individuals don't own them.

I saw something about these while I was digging around the internet for info, from what I read they aren’t going to help a ton with giving me the info I need, I could be very wrong though.
 
They are called XRF Analyzers. Several companies make them. Call around and see if you can find a large machine shop that has one. They are fairly prevalent for Quality Assurance Testing. They are quite accurate and will give you the basic composition of your metal. I don't know what they will charge. Take them some donuts (or beer maybe) and they might do it for free. I had a friend that bought one and he was charging $50 a test. But that was some time ago.
 
XRF will give you everything but the carbon content, you can usually tell without knowing that.

My guess is you probably have D2.

Appreciate it, not too sure about the D2 though. I’ve never worked with D2 but from what I recall it has decent corrosion resistance, not too far off from stainless, this stuff rusts just as bad as most carbon steels I work with. I could be very wrong though haha.
