I had a piece of 4140 slip out of my tongs and land in an ill-placed bucket of water. I had drawn it out to about 1/8" thick, and the overall piece was approximately 2" x 8", fairly flat and uniform. It was bright red / orange when it went in, and the bucket was deep enough that it fully cooled to a hand-safe temperature before I could fish it out. My hope was to turn it into a small leaf spring for a hardy tool, or at least experiment with it. I heated it back up to normalize it, for what it's worth. I couldn't see any visible cracks, but I also haven't cleaned any scale off yet. Should I bother working the piece anymore and hope for the best, or is it likely a lost cause? It's not an expensive piece by any means, and I don't have a ton of time into it (mostly the time involved in drawing it out from a round bar), but I'd love to salvage it for something if possible.
