Which of the following is an Austenitic stainless steel series? (rephrased)

• A. 300 series Stainless Steel
• B. 405 series Stainless Steel
• C. 316 series Stainless Steel
• D. 410 series Stainless Steel

Answer: (C)

Austenitic stainless steels are the nickel-stabilized, non-magnetic (or only weakly magnetic) group that have a face-centered cubic structure, giving them excellent corrosion resistance and good formability. The 316 stainless steel is a well-known grade within this family, notable for adding molybdenum to improve resistance to chlorides and pitting. That combination—an austenitic, nickel-stabilized structure with enhanced chloride resistance—makes 316 a classic and representative example of an Austenitic stainless steel. The other options come from different stainless steel families: 405 and 410 are part of the 400-series, which are ferritic or martensitic and not austenitic, while the broader 300-series is the general austenitic group, of which 316 is a specific, widely used grade.
