Annealed S20910 Stainless Steel
Annealed S20910 stainless steel is S20910 stainless steel in the annealed condition. It has the lowest strength and highest ductility compared to the other variants of S20910 stainless steel.
The graph bars on the material properties cards below compare annealed S20910 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.
