I'm by no means an expert here but I'll venture a guess. DEF is highly corrosive I have seen. I would think that most DEF tanks are plastic. I can tell you on my Chevy Duramax when I pour DEF fluid in under the hood, if a drop hits anything and I don't get it wiped up, a couple weeks later it's already left a white spot and eating away at whatever it's on. Now maybe some manufacturer use a metal that's coated, but I would think a thick plastic like a gas tank would be the norm.
