Annealed 403 Stainless Steel
Annealed AISI 403 is AISI 403 stainless steel in the annealed condition. The graph bars on the material properties cards below compare annealed AISI 403 to: wrought martensitic 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.
