1/16-Hard 316N Stainless Steel
1/16-hard AISI 316N is AISI 316N stainless steel in the 1/16-hard temper. It has the highest ductility compared to the other variants of AISI 316N stainless steel. The graph bars on the material properties cards below compare 1/16-hard AISI 316N 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.
