F-P Annealed (+FP) 1.6523 Steel

EN 1.6523 +FP steel is EN 1.6523 steel in the ferrite-pearlite annealed (FP) condition. The graph bars on the material properties cards below compare EN 1.6523 +FP steel to: EN wrought alloy 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.
