[QUOTE="J E Custom, post: 2034728, member: 2736"] In depth explanation of the process of Annealing and the metallurgical reasons. This video will explain time and temperature needed to do a proper anneal. it could help to get a better anneal or hopefully prevent over annealing and ruining the cases. Brass alloy used in cartridge cases has a melting point of 1700 Degrees F + or - Zink has a melting point of 787 Degrees F Tin has a melting point of 449 degrees F So the temperature becomes critical, if you over heat the alloy and start burning of the tin and Zink so the amount of time and temperature is important and we have to compromise to get the best outcome we can without ruining the brass. The ideal temperature normally cant be reached without over annealing or heating the entire case and softening the entire case. The video will better explain this and is worth watching if you are interested in the metallurgical reasons. [MEDIA=youtube]M8AxgPPoKkU[/MEDIA] J E CUSTOM [/QUOTE]
