Pre-hardened could be. Weird thing is that my bandsaw went through it, although it was making a racket. The bar was actually bent into an S-shape, it was one of those spring mounts they use for rakes on passive cultivators. Probably was bent under heat and then it hardened? I don't know why you'd harden something you want to use as a spring.
