I am trying to place more tension into a 6AL4V grade Titanium
Tension Set ring by heating it. It is not working.
While I’m not familiar with that titanium alloy, so I don’t know if
it can be heat treated, I’m wondering what your basis of assuming it
CAN be heat treated to harden it might be. Just curious…
Tension set rings are kind of a special case, needing more spring
hardness than many jewelry metals can be given by heat treating. Some
jewelers seem to be mislead by the assumption that heat treating can
always be used, simply from familiarity with the way steel can be
heat treated. Few jewelry metals behave that way. Sterling silver,
for example, can be age hardened to a useful degree to increase
durability, but I’d hardly call the result enough spring hardness to
make a useful tension set ring unless it’s very heavy guage metal.
Not all yellow golds will age harden much at all unless they’ve got
enough copper in them. Same with palladium white golds and most
There is a reason why the folks who developed tension set designes
most sucessfully, such as the late Steven Kretchmer, developed
specialized alloys to work with, or chose which alloys to use with
specific care. Many of the alloys we work with, even if they can be
heat treated to some degree, don’t harden enough to be a useful
tension set ring via heat treatment, and can only be sufficiently
hardened, if at all, by actual work hardening.
Are you sure your titanium alloy CAN be heat treated, or did you
just assume it must be the case? I’m not being critical here, since I
don’t actually know if that Titanium alloy will respond as you wish.
I’m just wondering if you are sure it’s even possible… As I said,
