Help Requested Will this ruin my superquench heat-treat?
I'm doing a batch of corkscrews in mild steel, hardening the actual screw portion using superquench. I'd like to rust-proof the entire piece, and I'm looking to do a flaxseed oil finish. My google-fu puts the smoke point of flaxseed oil at 225ºF, so I'd been thinking of baking the coated pieces at 230 or 235 for a few hours. Is doing that likely to undo the effects of using superquench, or am I safe as long as I stay below a particular temperature? If it is a threat, any suggestions for a comprehensive rust-proofing? The way I was taught just waxes the handle and leaves the screw bare, which had a bit of rust already forming on the screw in under a month, so anything that would improve on that would be appealing.
