ASTM SAE1026 Carbon steels are steels that contain only carbon as their specific alloying element. Traces of 0.4% silicon and 1.2% manganese can be found in these steels. Carbon steels also contain small quantities of residual elements such as copper, nickel, molybdenum, aluminium and chromium.
SAE-AISI 1026 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1026 is the designation in both the SAE and AISI systems for this material. G10260 is the UNS number.
The properties of SAE-AISI 1026 steel include two common variations. The property values on this page show ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare SAE-AISI 1026 steel to: wrought carbon or non-alloy steels (top), all iron alloys (middle), and the entire database (bottom). The length of each bar shows the given value as a % of the largest value in the relevant set.
