Thanks for the replys!

I have some of those SS bags for heat-treating but didn't have much luck
last time tried to use them, was concerned about the part cooling while I
opened the bag to get it to quench (at 1650F!).

Anyone got any tips? Do you put a match in with the part to "burn" the air
inside?

I think you just quench everything. When I have seen it used, a tool
that looks like a window-screen spline tool and a J-roller have been
used to smooth the SS around the part, basically eliminating all the
air. The goal is to effectively "plate" the part in stainless so that
there is no Ti exposed to the furnace. You definitely would not want
to put a match inside because the carbon from the flame would be bad.
