Is it customary to heat treat castings?  I thought it was for billet or 
stamped where treating stresses and hardening was applied.  Years ago I 
worked in aluminum foundries and nothing was heat treated...  One of 'us' 
listers out there is a metallurgical engineer, I think.  I'd like to read his 
input.  It would be interesting to see what vocations we encompass - since we 
all share at least one gene.
