Austenitic Stainless Steels

Of all elements added to the basic alloy of chromium and iron, nickel is the most important.  It not only improves corrosion resistance, but also changes the alloy’s structure and mechanical properties. The change in structure through austenization is accompanied by corresponding changes in ductility and toughness.  Austenitic stainless alloys make up a family of stainless steels that are by far the most widely used of all types.
