  • How to Prevent Galvanic Corrosion Between Carbon and

    Jun 21, 2019 · Carbon Steel. Carbon steel and stainless steel are both iron based metals, but carbon steel has an especially high content of carbon. This makes carbon steel notably strong, heavy, and hard. However, carbon steel is vulnerable to corrosion. That’s because it’s made of iron, and it’s easy for oxygen to corrupt iron.
