Odd question but I know lots of reloaders use wet cleaning systems to ,well, clean their brass. They sometimes dry the brass in the oven at low temperatures. I have read of this and remember someone saying only leave it in the oven for no longer than needed to dry. Well I have an oil-filled electric heater in my "room" and so I washed some brass and set the tin on the heater to dry the brass. Forgot about it till late the next day. Used a thermal temp gun to read the temp and it was 108 degrees f. Can this alter the properties of the brass? Kinda like annealing only backwards? Its not a lot of brass so scrapping isn't the issue. I just wonder what low/extended heat does to the structure of a brass case. Anything or nothing? Anyone?

It gets a little hotter than that here. You should try shooting at 115 with the sun beating on you. I don't think the brass even noticed.

How hot do you think it gets over in the sandbox.. Should be fine.

Re: Can heat drying damage brass?
I'm no expert, however it seems to me that extended 108 degree temp on the brass should have no effect. I cant see that getting the metallurgical properties out of whack. Hell i remember weeks over seas where we were lucky to hit 100 as a low.
Brass hammer hardens. Annealing brass is the opposite of hardening steel. When its rapidly cooled from a high temp it causes the grain structure to realign making it soft again.

Yes, heat will be detrimental for the web and can cause case head separation. 108 degrees though? No. That's typical summer shade weather here in the desert.

look how hot it gets when you shoot it

This from 6mmbr.com :
<span style="font-weight: bold"> Brass which has been "work hardened" (sometimes referred to as "cold worked") is unaffected by temperatures (Fahrenheit) up to 482 degrees (F) regardless of the time it is left at this temperature. At about 495 degrees (F) some changes in grain structure begins to occur, although the brass remains about as hard as before--it would take a laboratory analysis to see the changes that take place at this temperature.</span>
I doubt your brass reached even 200 deg.
