# Solution Annealed (+AT) 1.4606 Stainless Steel

EN 1.4606 +AT steel is EN 1.4606 stainless steel in the solution annealed (AT) condition. The graph bars on the material properties cards below compare EN 1.4606 +AT 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.
