They are the most widely used alloys in industrial as well as commercial space. They have an austenitic grain structure and remain stable under a wide range of conditions. They are generally non-magnetic in nature.
Their composition constitutes chromium, nickel and sometimes molybdenum along with nitrogen and other alloying elements. Nickel-based austenitic stainless steels are generally classified as 300 series alloys, among which grade 316 and 304 are extensively used. These grades are well known for their forming characteristic as well as corrosion resistance. Austenitic grades are known to be quite flexible with their properties, they can be formed into soft as well as significantly strong metals without losing their strength at red-hot temperatures. Their common applications include industrial equipment, automotive components, chemical industries, food equipment, etc.
