Hi
I bought some wrenches at a fire-damaged sale. They were burnt in a
fire at the tool store and were very cheap so I took the risk, but
find that they are useless and bend very easily. Is it possible to
reverse the softening by heat treating them in some way? They are ring
and openend style made from chrome-vanadium. Draper and Elora brand.

Looks like these were heated red hot and then cooled in the ashes. Classic
way to anneal.

Do you have enough of these to make paying a commercial heat treater to heat
treat them worthwhile?
