Brad, re-read post #52, this is explained to you.
No! It won't! Not at the Sn percentages your using. After 5% Sn it will some and the higher past that the more Sn will effect your outcome.
The temp you HT at WILL change the final BHN but only if you re-read post #52. If after you re-read post #52 you have questions ask, I'll try to explain it again.
