Stainless steel is used in construction, vehicles, electrical goods and more. It is an iron-based alloy that contains chromium. Carbon, nickel, copper, titanium, aluminum, silicon, and nitrogen are other elements that are found in stainless steel. This metal is ductile, magnetic and resistant to corrosion, abrasion, erosion and electricity. If you are not sure whether an object or piece of metal is stainless steel, there is a way to tell.
