Normalized 6150 Chromium-Vanadium Steel

Normalized SAE-AISI 6150 is SAE-AISI 6150 steel in the normalized condition. The graph bars on the material properties cards below compare normalized SAE-AISI 6150 to: SAE-AISI wrought 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.
