Most wear-resistant metal between 304, 316, and Ti

For the metallurgy experts, supposing they were otherwise dimensionally identical rap rings, which would get a groove worn in it soonest: 304 stainless, 306 stainless, or grade 2 Titanium?  I've already ranked them cheapest to expensive-est, and by corrosion resistance.  Just wondering about resistance to wear.

Thanks.

The stainless steels there is no difference, the titanium wears roughly twice as fast. There is a long thread on this subject and the tests I have done if you search.

Thank you.  I'll look for it.

Hi again Jim,

With apologies for my poor search skills, I can't find a thread that specifically addresses this: only one where someone asserts that Ti is MORE resistant than SS.  Any chance you (or anyone more search-savvy) could link to it?

I found your website very informative for some other matters, but couldn't find this specific answer.  I'm also interested (since you've done some pretty thorough research), in the heat-dissipation properties of different metals: how much would a SS rappel plate heat up vs a Ti one.  I've found anecdotally that Ti absorbs heat slower than SS, but I'd love to see some published research, if it's available.

There are probably others, but in this thread Jim describes some tests comparing SS and Ti quicklinks.

That's the one.

Thanks very much--I browsed past that title but didn't know that the test was further down.  There's a lot of yelling at the beginning.

Really glad for that beta.  That's the exact test I wanted to see done.  Killer work on Jim's part.  I've used a abrasive rubber wheels to polish and de-burr stainless and Ti, but they're not rough enough to cause meaningful wear within my attention span parameters.
