Look for the hardness in the standard in normalised condition (usually) or Hardened and tempered condition

Did you consider EN40B or EN41 too (they are good nitriding alloys with quite high core strength)

This question sound like it should be in the Mechanical Engineering section. Check on the left of the screen for ME.
