Austenitic stainless steels
Contain high amounts of chromium and nickel and are the most corrosion resistant, ductile, and weldable type of stainless steel, designated as 300 series (such as type 304 and type 316). The largest selling type of stainless steel, they have face-centered crystalline structure and are used mainly for heavy duty work such as chemical industry equipment, food processing equipment, and truck/trailer bodies. Named after the UK metallurgist Sir W. C. Roberts-Austen (1843-1902). See also ferritic stainless steels and Martensitic stainless steels.
