SAE-AISI 1005 (G10050) Carbon Steel
SAE-AISI 1005 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the cold worked (strain hardened) condition. 1005 is the designation in both the SAE and AISI systems for this material. G10050 is the UNS number.
It has a fairly high thermal conductivity among wrought carbon or non-alloy steels. In addition, it has a fairly low electrical conductivity and a very low tensile strength.
The graph bars on the material properties cards below compare SAE-AISI 1005 steel 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.
