Cold Finished 5160 Chromium Steel
Cold finished SAE-AISI 5160 is SAE-AISI 5160 steel in the cold worked (strain hardened) condition. It has the lowest strength and lowest ductility compared to the other variants of SAE-AISI 5160 steel.
The graph bars on the material properties cards below compare cold finished SAE-AISI 5160 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.
