Half-Hard K93600 Alloy
Half-hard K93600 is K93600 alloy in the half-hard temper. The graph bars on the material properties cards below compare half-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.
