Stainless steel

Stainless steel is characterised by containing a minimum of 10.5 per cent chromium. Stainless steel is fairly corrosion-resistant. This is due to the high content of chromium, as the chromium seals the surface of the metal with a thin, passive layer of insoluble oxides.

If you are in doubt as to which type of stainless steel to choose for your project, you can learn more below or call us and we will help you choose the right type of steel.

Stainless steel comes in a variety of qualities. It is the composition of materials that determines its quality. The table below lists the composition of materials of different types of stainless steel:
