On this subject, I wanted some data on silver steel tonight. I searched for "silver steel" and this is what came up:
By the way, I was wanting to know (very roughly) how much harder silver steel is compared to mild steel. I can get a good variety of round silver steel in small quantities, but have had a little difficulty threading it with a die. Maybe this is just to be expected?

Yes, it is harder. Silver steel is called "drill rod" in the US, so you might get more hits googling.
silver steel here in Germany is 1.2210, the US drill rod is a bit better quality. Yours (British) is quite the same as ours.
1.2210 is 115CrV3 Have no data about strength. MS (CRS) would be 1.0037 AKA S235JR or something in that ballpark. It has a upper yield stress of 235 N/mm^2 or a tensile strength of about 360 N/mm^2
Yes. Use cutting oil (as always), that helps.

Just as drill rod is.
Enjoy, DoN.
