UNS S30600 (310L NAG) Stainless Steel
S30600 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. S30600 is the UNS number for this material. Additionally, the common industry name is 310L NAG (Nitric Acid Grade).
The graph bars on the material properties cards below compare S30600 stainless steel to: wrought austenitic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
