Which steel is tougher?

[fielder]

Hi, which steel is tougher, everything else being equal, Aus 8 or Xhp?

 

[jbmonkey]

the xhp, all things equal like optimal heat treatment etc, will have better toughness than the aus8.

If both were taken to the 60-61HRC I understand the XHP is taken to, then the XHP would be tougher, however the AUS8 is run at 57-58HRC which means its heat treatment favoured toughness over hardness. The BD1 is, I understand, also run at 57-58HRC at which point it is tougher than the AUS8 at the same hardness.

XHP is probably tougher, but we'll have to wait and see some comparisons.

Well, XHP steel holds an edge longer compared to aus8, but it´s also much more expensive.

What do you mean by "tougher"?

What do you mean by "tougher"?

im sure you are already aware of that judging from your tone but just in case you need something more specific beyond the literal meaning of "toughness".

At the same hardness XHP should have an advantage in transverse toughness. I have no idea whatsoever about longitudinal toughness or how XHP at 61 would compare to AUS8 at 57.

I mean at the hardness Coldsteel runs each steel at.

People use terms pretty loosely sometimes. In that case, AUS-8 has the most toughness potential.
