Need help finding proper alloy
(OP)
I hope this is the best forum... doesn't seem to get too much activity.
I'm looking for the most abrasion-resistant steel alloy I can get my hands on for a reasonable price. Suggestions?
Some helpful info... the application will involve close proximity to hand-held high-speed steel (HSS) tooling and sandpaper of various makeups (garnet, silicon carbide, etc.) while being spun on a lathe. As these will be used as sizing guides, the intent is to provide as much resistance to the tools and sandpaper reducing the diameter of these pieces as possible.
I realize there may be a trade-off in abrasion resistance versus cost to mill these guides, but I need as much info as I can get so I can make an informed decision. Increased costs of, say, 10% to mill a significantly more resistant guide is perfectly acceptable... a 100% increase may or may not be, depends on the final cost.
I hope all of that is clear.
Thanks!

What is the typical depth of the nitride layer? If the sandpaper or hand tools can quickly scrape it off, it may also be a low ROI for the time / money.

Others would require the parts being placed on hooks on a rack, simple and fast.

Hand-held HSS tooling is going to lose its edge or fracture the first time it caresses AR steel.
That may not be what you want to happen.
Quantity 10,000 little doodads just screams "screw machine".
Screw machines can deal with leaded steel, but they like leaded brass a lot better.
Once you get them set up, and I think you can lease them in tooled condition, a superb machinist is not necessary; you just need a person to feed them bars, check the parts to detect worn or broken tools, change the tools, shovel out the parts and chips, separate the parts from the chips, clean the parts, clean and dry the chips, and pack the chips. You pack the chips because you can buy brass on a net part basis, i.e. you send back clean chips and get a credit against the brass cost.
Oh. Hardness and abrasion resistance. Nickel plate the brass doodads.
