I'm not a metallurgist, but it would be interesting to hear if in fact the level of heat generated via these methods would actually have any affect??

Hmmmmm....

We were building a stainless tank at work about two years ago, and every morning we got a different measurement than in the afternoon heat.
Keep in mind this things circumference was over 140 feet and the material was 3/4 in. thick.
Every day it would " grow" 3/8 to 1/2 in. as the day got warmer. That being said what would a temp change of 50 degrees do to a piece of steel where at its smallest point ( not counting the sharpened edge itself ) is just thousandths of an inch thick?

Just something to ponder.
