Aged Half-Hard S46910 Stainless Steel
Aged half-hard S46910 stainless steel is S46910 stainless steel in the cold worked and aged condition. It has the second highest strength compared to the other variants of S46910 stainless steel.
The graph bars on the material properties cards below compare aged half-hard S46910 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.
