[TheForge] Fw: -Hay rake tines

[David E. Smucker]

Paul,  These are a good set of charts on various steels.

For what it is worth, I always treat 1095 and W 1, as the same steel. 
Mostly we see W 1 in the form of drill rod.  1095 really is very similar, if 
not the same steel and they heat treat the same for all practical purposes. 
Remember that our heat treat process is "crude" but still results in very 
useful tools.

Dave
