Stainless steel is a steel alloy which has 11% chromium content. There are many interesting facts related to stainless steel. When a few elements like titanium, aluminium or nickel are added to stainless steel, it increases its corrosion resistance properties. Chromium creates an oxide film on the outer surface of stainless steel. This film is what gives stainless steel its corrosion resistant properties. The austenitic steel grades are usually non-magnetic. Ferritic is a magnetic type of stainless steel. Stainless steel is generally available in more than 100 grades and each grade has a specific purpose or application.
