This is an interesting topic and I have to reread the whole works to consider both composition, heat treating and straightening...but while I take time to do that - here is a slightly related / unrelated thought. Many years ago I talked to an old fellow who worked in Guelph at a foundry. It was closed down due to heavy contamination and possible liability issues related to the site. At that time Bill Gregg had the remains of an old WW1 tank ( no turret or duck tail. v8 engine etc) These were the tanks sent to Camp Bordan from the usa at the start of ww2. I was telling the old guy about this and he told me that several of these types of tanks ( hulls only??) were in fact buried on the foundry site because many of the vehicles were scrapped there after the war. The suggestion was that somehow the composition of the steel plate was such that it was difficult to melt or convert into usable scrap. Anybody know more about this??
