Stainless Steel for Impact

[mewhg]

Can someone suggest a stainless steel that can be hardened to 55 RC and has good impact toughness?

Corrosion resistance is really not an issue as I am only considering stainless as a replacement for low alloy carbon steel because stainless responds better to a nitriding process I am considering.

Thanks in advance.

The classic grade for this is 420. There are several much more expensive grades which are sometimes used for knife blades, which engineers at Crucible or Timken/Latrobe could help you with.
