Why doesn't stainless steel furniture rust?

Stainless steel remains stainless, or doesn't rust, due to the interaction between its alloying elements and therefore the environment. chrome steel contains iron, chromium, manganese, silicon, carbon and, in many cases, significant amounts of nickel and molybdenum. Chromium present within the steel reacts with oxygen to make a protective oxide layer. The presence of the stable film prevents additional corrosion by acting as a barrier that limits oxygen and water access to the underlying metal surface.

Because the film forms so readily and tightly, even only a couple of atomic layers reduce the speed of corrosion to very low levels. But sometimes chrome steel can rust. If you're experiencing rust on your chrome steel, you're not alone. There are over 150 grades of chrome steel and a few are more susceptible to corrosion than others. Generally, the upper the chromium content, the less likely the steel will rust. However, over time, rust can and can develop on chrome steel.

To prevent chrome steel from rusting, you would like to passivate it. Passivating chrome steel may be a process that permits chrome steel to retain its corrosion resistance. There are a couple of factors which will affect the corrosion resistance of chrome steel. The composition of the steel affects corrosion resistance. Even within grades of chrome steel, impurities within the steel can affect the corrosion resistance. The environment is another big think about chrome steel rust. Environments with chlorine, like swimming pools, are highly corrosive. Salt water environments affect chrome steel, just to a lesser extent than steel. altogether environments, properly passivating your chrome steel furniture will prevent it from rusting.

Although rust are some things we see on an everyday basis and appears to be an easy occurrence it may result from variety of complex processes. Understanding the materials science of metals is critical to making sure correct product performance and fixing issues, like rust, as they occur.
