Annealed S46500 Stainless Steel
Annealed S46500 stainless steel is S46500 stainless steel in the annealed condition. It has the lowest strength and second lowest ductility compared to the other variants of S46500 stainless steel.
The graph bars on the material properties cards below compare annealed S46500 stainless steel to: wrought precipitation-hardening 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.
