Alloys of stainless steel are made of iron and at least 10% chromium. The ‘passive layer is a thin coating of oxide (Cr2O3) formed on the steel surface by chromium. The steel is protected from corrosion by this protective layer. Steel that has more chromium is more resistant to corrosion.

When contrasted to conventional steel, stainless steel doesn’t corrode or discolour. This is due to the alloy’s high concentration of chromium.

How does stainless steel differ from regular steel?

Chromium is present in stainless steel, whereas carbon is an alloy in plain steel. Because of chromium’s internal structural modifications, stainless steel is known for its extremely resistant characteristics, as well as its non-staining surface.

It is the chromium that gives stainless steel its corrosion-resistant properties. The higher the level of chromium in stainless steel, the better it will be at resisting corrosion and staining.


  • Higher corrosion resistance
  • Higher Tensile strength
  • Temperature tolerance
  • Corrosion Resistance

The Chromium present in stainless steel offers a self-healing protective oxide layer that makes it corrosion resistant. The self-healing behaviour of the layer means the corrosion resistance remains solid regardless of its fabrication methods.

The corrosion-resistant property of stainless steel will differ with various atmospheres and environments for its different grades. Grades have high chromium content, molybdenum and nickel being the most corrosion-resistant of stainless steels.

What are the other benefits of stainless steel?

Stainless steel don’t need to be painted or coated like other types of steel. This saves on time and costs associated with maintenance and repair.

Stainless steel is also recyclable.
