Full-Hard K93600 Alloy

Full-hard K93600 is K93600 alloy in the full-hard temper. It has the highest strength compared to the other variants of K93600 alloy. The graph bars on the material properties cards below compare full-hard K93600 to: low-expansion iron alloys (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.
