What is stainless steel
Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of
the steel known as the passive layer. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives
an increased resistance to corrosion.
Stainless steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may
be added to impart other useful properties such as enhanced formability and increased corrosion resistance.
