80% of Philadelphia Supply Depot brass stock wrong alloy

Afterwards they looked at this brass fitting, and it was stress corrosion cracking. The student got up and gave this little presentation of what they had found. It turns out another student in the class was working in the Philadelphia Supply Depot about the same time. When they found that it was the wrong brass alloy — it was not the correct alloy specified by NAVSEA for this application, and that's why it had failed by stress corrosion cracking — of course they go and say, well, check our Supply Depot and make sure all the stuff in stock is correct. 80% of the stock in the warehouse was the wrong alloy. That student wasn't planning to present that, but as part of our discussion she said, oh, I was in the supply at that time and we found 80% of the stuff was bad.
