It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure. — Albert Einstein

Gwinn said something about that, I forgot why but there was a good reason for it. cast iron either. when you start getting into electrical low carbon iron you start talking expensive....It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure. — Albert Einstein

steel is real confusing, there is ASTM ans AISI then there are trade name alloys, I think half my brain melted researching iron and steel alloys this last year.http://www.SDpickups.com

I was curious about the studs I make so I ask my steel supplier for the certificate of analysis regarding the 3/16" cold roll rod they sell. And BTW no they don't sell C1022 rods.
Carbon, C 0.15
Iron, Fe 99.001
Manganese Mn 0.7
Phosphorous, P 0.009
Sulfur, S 0.03
Chromium Cr 0.11
I did a search on chromium vs magnetism and I found this:
http://en.wikipedia.org/wiki/Chromium
Chromium(IV) oxide (CrO2) is used to manufacture magnetic tape, where its higher coercivity than iron oxide tapes gives better performanceLast edited by EtLa; 03-03-2008, 08:21 PM.

Possum, you might post over at http://practicalmachinist.com in the "general" section. That's the largest collection of machinists you're likely to find on line and if they can't help you then I suspect you'll have hit a dead end. There are more than a few guitar makers over there so you won't be in totally foreign territory.

What is the alloy you're getting called, and who sells it?http://www.SDpickups.com

Here is where i get the rods (in french only) http://www.aciermajeau.com/ but they are retailer, I don't who make the cold roll rods for them.

I think I misread the amount of carbon there, 15 points of carbon, I thought it was 1.5 points. Oh well, the chromium is surprising, hmmmmm.....http://www.SDpickups.com

I guess they add stuff to iron for rust resistance.It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure. — Albert Einstein
