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.
Stick the magnet on the piece you are testing. If it holds firmly, the metal is possibly stainless steel. If not, it is another metal such as aluminum.
Pick a spot on the piece that you don't mind damaging a little.
Fill the eye dropper with muriatic acid. Drop a small amount of the acid on the test spot. Wait half an hour.
Wipe the acid off the piece. Examine the test spot. If it is discolored, the piece is stainless steel.
