Those hard angle irons may have been bed frame material. Mattress bed frame rails are HARD!

More phase diagrams, run for the hills ! Things of nightmares I tell you. amazing stuff metalsmith. I once bought a scrap load of 1.5" angle iron. Like 40 sticks at 10 feet long. Lovely used material. Some how some way it had been heated to a point it had been hardened to the point a drill bit would not penetrate it. I had welded a trailer frame out of it. Only to find I could not do a lot of needed drilling to hold wood decking down. Phase changed. Trailer frame still sitting in bone yard. Useless. Polyethylene can be amalgamated using a hot air gun. Once it cools the bends put into it stay put. Not sure if that falls in the semi-molten state or phase change category. You could use a torch to heat and change the phase in the spots where you want to drill. Like annealing work hardened copper, silver, etc.
