[TheForge] looking for a chart

[Dave Mudge]

Thanks Peter,
I do know, but I am working in a small rural machine shop where the
boss thinks that every application of needing a hardened or tough
steel can be filled with 4140
Actually I think that he doesn't know of any other steel. So, on the
gentle path of enlightenment, I will find many other steels and specs,
and applications and bring them into the light (along with info on
each type).
