Annealed M10 Tool Steel
Annealed SAE-AISI M10 is SAE-AISI M10 steel in the annealed condition. The graph bars on the material properties cards below compare annealed SAE-AISI M10 to: tool 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.
