Austenitic Stainless Steel: A Complete Guide to Grades, Properties, and Uses 

What is Austenitic Stainless Steel?  
 

It is the most widely used and versatile family of stainless steels, valued for its exceptional corrosion resistance, formability, and reliable performance across a wide temperature range. Its unique metallurgical characteristics make it an essential material for critical applications in industries from petrochemicals to food processing. 

This steel's properties are primarily defined by its high chromium and nickel content. Chromium provides a passive, corrosion-resistant surface layer, while nickel stabilizes the steel's crystal structure. The resulting austenitic stainless steel microstructure features a face-centered cubic (FCC) lattice, which imparts excellent ductility and toughness. This structure is non-magnetic in the annealed condition and can be hardened only by cold working, not by heat treatment. Its reliability and adaptability make it the preferred choice for countless engineering specifications.
