The layer can be damaged by scratches and sustained exposure to aggressive chemicals, however, because the layer is formed by the reaction of the chromium with air, when the surface is suitably cleaned, the protective chromium oxide layer self-repairs to continue to protect the steel. This layer is not visible to the naked eye and protects the surface from corrosion. The chromium in the stainless steel reacts with the oxygen in the air creating a very thin, protective chromium oxide layer on the surface of the metal. Stain’less’ steel is just that…stain’less’ and not stain’never’.

Stainless steel has become very popular due to its relatively low cost, aesthetic appearance, high corrosion resistance and low maintenance. Although grades such as 304 and 430 are popular grades, the term ‘stainless steel’ covers a wide variety of metals, each enhanced with various alloying elements to give specific properties such as increased corrosion resistance or improved strength. Stainless steel is an iron alloy, containing a minimum of 10.5% chromium. We stock vast quantities of grades to cater for projects of all sizes and complexities. The Chromium content in the steel is very important as it creates a thin layer of chromium oxide on the surface of the metal to prevent corrosion and usage of the metal. 'Stainless' is a general term for stainless steel which requires a minimum of 10.5% Chromium.
