How Hard Is My Luger...? <IMG SRC="/luger/graphics/wink.gif" BORDER=0 ALT=";)">

I hate to be the "Bringer of Bad News" But,Rockwell "B" scale number is not the same as Brinnell number.

In fact the two are separated by about a factor of 2 at the hardest end of the scale and by a factor of about 3 at the softer end of the scale.

So the only relation between the two are by a comparison chart that relates all of the different methods of hardness testing values.

Sorry to have to correct you but it could be a fatal mistake to mix the two values.
