Spheroidized and Cold Drawn 1065 Carbon Steel
Spheroidized and cold drawn SAE-AISI 1065 is SAE-AISI 1065 steel in the spheroidized and cold-drawn condition. The graph bars on the material properties cards below compare spheroidized and cold drawn SAE-AISI 1065 to: wrought carbon or non-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.
