This week’s video is courtesy of WorldStainless.org, a non-profit research organization which serves as the world forum on various aspects of the stainless steel industry.  While a bit cheezy, the video does a great job of explaining one of stainless steel’s greatest characteristics, the ability to self-repair.  Known within the industry as self-passivation, this is stainless steel’s ability to build, and re-build, a protective layer even after the surface is scratched or damaged.

Some of the key points from the video:

• All steels are not created equal.
• Stainless Steel has added chromium, which reacts with air to form a thin, invisible protective layer on stainless steel.
• If the surface is damaged (i.e. scratched), the protective layer reforms, or self-repairs.  This process is known as self-passivation.
