  600 F austempering
  63 Rockwell C as quenched

  This is a wonderful tool steel - high resistance to warpage, very tough, and typically used in leaf springs, hence it adds flexibility.

    Acquired from the usual steel suppliers. Typically, a 1.5" x 1/4" thick bar x 22' is under $75, which means that a normal knife blank runs maybe $3..$5. There is little motivation to recycle old leaf springs to get 5160!
