If you live in a state where snow and ice covers the ground each winter, you’re probably well aware of just how necessary it is to de-ice the roads. Since the 1930s, when salt was originally realized to work for this purpose, agencies have been using this tried and true method to keep roads safe for driving. Salt works because of its natural ability to melt ice without adding too many harsh chemicals to the environment. But salt is, as we’ve all seen evidence of, quite corrosive and over time, it can cause vehicles to rust, shortening their life spans.
Beginning in 1976, NACE International (formerly the National Association of Corrosion Engineers), based in Houston, Texas, routinely started to study corrosion rates on older vehicles. At that time, 90% of vehicles six years old or older had rust damage. Most of that rust could be attributed to de-icing (although living near bodies of salt water where the air has a higher salt content was also a key factor).
Manufacturers of automobiles saw a need to improve cars being sold in coastal areas and the snowbelt region of the United States. They started to make improvements which included stainless steel...
