Hello, I have a question...
having to tempt a ring of øe=700, øi=650 and thickness 8mm that steel would recommend me?? the problem is that I have to harden the upper surface, on which it will roll a roller bearing. My fear is that this so thin ring deforms a lot. . .
what steel and what treatments do you recommend? ?
Thank you.

I think no one answered you because the question is too generic, it can depend on loads, working conditions, lubrication, etc.
However, in these cases the 100cr6 is used with a heart-temperature to have a long-life component, up to the possibility of choosing a c40 with a surface tempering to stay in the economy.

Hi.
If the application is pushed, it is necessary to resume the ring with post-treatment work.

Don't worry, he'll be deformed... and a lot.

as a well-known bearing house teaches us. . .http://www.skf.com/portal/skf/home/products?maincatalogue=1〈=it&newlink=1_0_58
the most widespread all-hardening steel for bearings is a chrome steel, containing about 1% carbon and 1.5% chromium, in accordance with ISO 683-17:1999. and also
the thermal treatment to which it is subject is normally martensitic or bainitic type during which it is tempered from 58 to 65 hrc.then.. depends on so many things
you can also do it in 41 crals and nitrurarlo at 900 hv .
