The antibacterial properties of stainless steel
Stainless steel, is a metal alloy composed mainly of iron, chromium, nickel and sometimes other elements. It is renowned for its antibacterial properties, which make it a material commonly used in environments requiring strict hygiene, such as kitchens, hospitals, laboratories, collective catering, etc. Here are some of the antibacterial properties of stainless steel.
Formation of a protective layer
When stainless steel is exposed to air, it reacts with oxygen to form a thin layer of chromium oxide on the surface. This layer, known as passivation, protects the steel from further chemical reactions.
Corrosion resistance
The chromium oxide layer prevents corrosion and rust formation, which is essential for maintaining a clean and hygienic surface.
Difficult for bacteria to attach themselves
The smooth surface of stainless steel makes it harder for bacteria to attach and multiply. This means they are easier to clean and disinfect.
Resistance to heat and chemicals
Stainless steel is often used in environments where strong disinfectants or cleaning agents are required. It is able to withstand most common cleaning chemicals.
Durability
Stainless steel is a robust material that resists physical damage, meaning it remains smooth and free from cracks where bacteria could hide.
However, it's important to note that although stainless steel has antibacterial properties, it's no substitute for proper cleaning and disinfection. It is always essential to follow recommended cleaning and disinfection protocols to maintain a hygienic environment.
