Below 28 HRC and Wear Resistant

Below 28 HRC and Wear Resistant

Below 28 HRC and Wear Resistant

(OP)
I need to make a decision for a material to be used as a stand to hold studs and bolts while they are being roll threaded. The material would need to be at <28 HRC and reasonably wear resistant. The bolts and studs will be continually rolling over the surface which is where the need for wear resistance comes from. The bolts are typically made of 4340. I was thinking something along the lines of aluminum bronze due to its softness yet good wear resistance properties. However, I do not know if material contamination is something I should worry about if I went along that route. I could also use annealed 4340 to avoid any contamination issues. Could someone help point me in the right direction as far as material type and factors I should be considering go?  Thank you

RE: Below 28 HRC and Wear Resistant

I don't see anyway where Aluminum Bronze would be a problem.  Brass and bronzes are used on all sorts of clamps and guides, etc.  

Have you looked at UHMW polyethylene?
 

RE: Below 28 HRC and Wear Resistant

Good choice and you could also heat treat aluminium bronze to the required hardness level.

RE: Below 28 HRC and Wear Resistant

FWIW, work rests or blades for thread rolling machines are usually made out of cemented carbides in order to achieve very good wear resistance.  Here are some examples from one manufacturer:
