I am trying to find the hardest stainless steel (round rod) in 3/32. I tried 303 but its just way to soft. I am trying to reduplicate a piece. Its slightly magnetic, but not hardened by any means. Just hard after its pressed in place. They call it spring steel, but it doesn't rust. I am also finding it hard to find any stainless in 3/32. There part is has round rod 5/64 (stainless)
