- Note on carbon content: In the AISI (SAE) designation, the 10 indicates an ordinary plain carbon steel, and the last two digits give the nominal carbon content, e.g. a 1035 contains approximately 0.35% carbon.
- The A36 (ASTM designation) contains approximately 0.26% carbon and would be roughly equivalent to a 1026. The A36 may also contain alloying ingredients including Cu and Mn.
