Editor’s Note: This is Part 3 in a 3-Part Infographic Series on Stainless Steels.
Stainless steel is made by adding varying amounts of chromium (Cr) and other alloying elements to
iron and carbon. When chromium is added to steel, it forms chromium oxide, a corrosion-resistant
product. Chromium is added in quantities ranging from 10.5 to 30%, depending on the application or
environment in which the steel is to be used. There are five main grades of stainless steel: austenitic,
ferritic, martensitic, duplex, and precipitation hardening.
Martensite stainless steels, named after German researcher Adolf Martens, contain high amounts of
chromium but very little nickel or other alloying metal, and are strong but brittle. Take a look at this infographic and discover a few things about Martensitic stainless steels.
