What is stainless steel?

In the metallurgical industry, the term stainless steel (stainless steel) is used to describe a form of iron alloys containing minimum 10.5% chromium. Called "stainless steel" but actually it's just iron alloys do not change color or corrode easily as conventional steels. This material may also be referred to as anti-corrosion steel. Typically, there are many different ways to apply stainless steel for different surfaces to increase the longevity of materials. In life, they appear everywhere as the blades cut or strap watches ...

 

Stainless steel is resistant to oxidation and corrosion is very high, but the choice of the right type and their technical specifications to fit in each particular case is very important.

 

The ability to resist oxidation from ambient air at normal temperature of stainless steel is due to the ratio of chromium in the alloy (as low as 13% and can be up to 26% in the case of work in harsh working environments). Oxidation state of the chromium oxide usually chromium (III). When chromium alloy steel in contact with air is a very thin layer of chromium oxide III appeared on the surface of the material; This thin layer that can not be seen with the naked eye, meaning the metal surface is still shiny. However, they absolutely do not react with water and air, it protects the steel layers underneath. This phenomenon is called the oxidation rust engineered materials.
