Austenitic stainless steels contain austenite, a form of iron which can absorb more carbon than ferrite. Austenitic stainless steels are non-hardenable by heat treating. Thermal Properties of Austenitic Stainless Steel. Outokumpu austenitic stainless steel series 200 and 300 have become a staple of a wide range of industries, such as chemicals, pharmaceuticals, food and drink, textiles, and pulp and paper. Stainless steel is a broad, and ever-expanding, category of corrosion-resistant alloys. As with all of our stainless steels, we produce our austenitic steel grades to the strictest quality standards and performance requirements. The most widely used type of stainless steel is Austenitic steel. This central iron atom is what gives ferritic stainless steels their magnetic properties. Ferritic stainless steels are less widely-used due to their limited corrosion resistance and average strength and hardness. By adding elements such as Molybdenum, Titanium or Copper , the properties of the steel can be modified. Austenitic Stainless Steel Grades. Other elements such as nickel, copper and molybdenum can also be added to change the properties of the material. Summary – Austenitic vs Martensitic Stainless Steel. They range from basic grades like 304 through to super austenitics such as 904L and 6% Molybdenum grades. Many different stainless steel compositions exist, with different additives bestowing different characteristics upon each different alloy. The austenitic microstructure and the high shapeability associated with it result in outstanding toughness properties, even at low application temperatures. The fundamental component of a stainless steel alloy is a minimum chromium content of 10.5%, with varying quantities of carbon, silicon and manganese. Austenitic Stainless Steel. Properties of austenitic steel The group of austenitic stainless steels has the advantage of high resistance against aggressive environmental conditions, particularly corrosion attacks. Austenitic stainless steels are classified in the 200 and 300 series, with 16% to 30% chromium and 2% to 20% nickel for enhanced surface quality, formability, increased corrosion and wear resistance. Austenitic stainless steel is a form of stainless steel alloy which has exceptional corrosion resistance and impressive mechanical properties, while martensitic stainless steels is an alloy which has more chromium and ordinarily no nickel in it. It has excellent mechanical properties, high temperature oxidation resistance and heat resistance. AISI 310 Stainless Steel (UNS S31000) AISI 310 stainless steel is a high chromium nickel austenitic stainless steel with a high carbon content. The Engineer's Guide to Austenitic Stainless Steel. But different materials react to the application of heat differently. Austenitic stainless steel contain a minimum of 16% chromium and 6% nickel. As a solid absorbs energy in the form of heat, its temperature rises and its dimensions increase. Thermal properties of materials refer to the response of materials to changes in their temperature and to the application of heat.
