Any large, heavy plate is sometimes referred to as "Panzer Platte" in German. If it were cast out of a higher grade, more expensive steel, it would surely be designated "Stahl Platte", to set it apart from a "Guss Platte" (cast iron plate). So much for the language and terminology. But who knows exactly what Kaps' plate were made of? One definite answer would be the results of a lab test of a piece of the plate...
