410 ss straightening

percy

Well-Known Member
I bought part of a sheet of 410 ss 3/16 thick. I am going to use it to mill folder frames from. I had some strips water jet cut for me and they warped. Not a lot but enough. How would be the best way to straighten them or flatten them out. I tried surface grinding but the magnet sucks them back straight so even after grinding they are still warped a little. Does someone have an idea on how to do this? Could I put them in the oven bring them to critical temp and then put them between my 2 inch thick 12 inch square plates, would that do it? Help if anyone can tell me is appreciated.
