tested steel of .060" thich with hand held rockwell hardness test tool.
results showed 19. what would that be equivalent to?

Thanks

Which handheld -- the Ames? That one (which I have one of),
IIRC, is made to measure purely Rockwell C scale. And for something
that thin, you want a Superficial scale instead, which requires a
different indenter, and a different maximum pressure. Predicting what
it would be is beyond my capability -- there is a reason that hardness
testers are made with separate scale capability -- conversion between
Rockwell C and Superficial when the thickness of the material pretty
much demands superficial is not a simple matter of looking up a table.

Good Luck,
DoN.
