stainless steel metal is an iron alloy that is corrosion-resistant. It is a very versatile material that can be used in a variety of different industries.
It is a popular choice in architecture due to its strong, resistant properties and aesthetic finish. It is available in a wide range of surface finishes, from matt to bright and can be brushed, engraved or embossed.
The chromium and other elements added to the base alloy increase the material’s strength, elasticity and durability. It also helps to improve formability, heat resistance and corrosion resistance.
When stainless steel is exposed to air, the chromium in the alloy reacts with oxygen on the surface to create a thin, stable passivation layer of oxidized chromium oxide (Cr2O3). This passive layer greatly increases the material’s corrosion resistance and minimizes rust.
Achieving this protective layer is a complex process that involves controlled heating and cooling rates, as well as chemical processes. It is one of the last steps in the manufacturing process.
Another important part of the process is descaling and pickling. This process removes any scale that has accumulated during the production and is essential for creating the oxide barrier that provides stainless steel’s corrosion resistance. It can be achieved by using either acid baths or through controlled heating and cooling.
