[TheForge] Quenching mild steel - Hochewa ?

[Rick Crawford]

I know that you guys really do know what you are talking about, but I get
lost as soon as you say Martensite, pearlite, or whatever.  Is there an
online place that I could go to and downlooad something that would teach me
about this stuff?

Thanks,
