Good day!
The body of the lid is made of black plastic. However, this is not chrome-plated but covered with polished stainless steel sheet. It almost looks like chrome-plated, but it is stainless steel sheet.
Many greetings

No. The plastic parts are not chrome-plated. There is a metal lid on top. However, I doubt that it is chrome-plated.

Yes, unfortunately the lid is made of plastic, only the top is chrome.
