Austenitic Stainless Steel

Austenitic stainless steels are iron-carbon alloys that have sufficient inclusions of austenite-stabilizing elements - nickel, manganese, and nitrogen - to create an austenitic substructure. 200 Series stainless steels use manganese and nitrogen to achieve their austenitic structure, whilst 300 Series use nickel.

Austenitic stainless steel is the most commonly used of all stainless classes and is home to the single most oft-used stainless steel alloy of all - 304, or 18/8. This class is renowned for its corrosion-resistant properties in particular, with many also featuring high strength, good machining and welding properties, good formability, and high-temperature strength.

These alloys are used across a broad range of industries with marine applications, medical equipment, food service, kitchenware, household appliances, chemical processing, petrochemical refining, sanitaryware, construction, heat exchangers, furnaces, and cryogenic uses just a few examples.

Integ Metals supplies 31 different grades of austenitic stainless steel in total, so please read below for more information on characteristics and available shapes, or speak to our expert sales team directly.
