Default Another hard as hell material like bed frame

I found another hard material to add to bed frame, t-bar,and road sign posts. Sash weights. I have a bunch of them and figured it would be good to make pins to press out bushings with a press. I put it on the bandsaw to square the ends and it wouldn't even scratch it.

The sash weights I'm familiar with are cast iron. Probably white iron due to fast cooling. If so, it is very hard due to iron carbides that form. As in 47 - 65 Rockwell C.

I always thought they were cast iron too. I wonder if they could be annealed.

Annealing some white iron into something like malleable iron apparently takes a day or two at about 950 °C (1,740 °F) and then slow cooling over a day or two.

Why bother when there are so many better materials available?
